LETTER FROM THE CEO
- --------------------------------------------------------------------------------

Dear Shareholders,

[Photo of Robert J. Manning]

Last summer and fall, I wrote to you about enhancements that MFS(R) was making
to its investment process. Our goal, as always, was to deliver strong
performance across all asset classes. I am now happy to report to you that
2004 was a very successful year for MFS, relative to our peers in the mutual
fund industry. While there will always be room for improvement, we believe the
enhancements we have made to our investment process resulted in significantly
improved performance across the MFS Family of Funds(R).

You may remember some of the enhancements I outlined last year.
They included

  o increasing collaboration and information sharing among our investment
    personnel across asset classes, through an Investment Management Committee
    with members from our Domestic Equity, International Equity, Fixed Income,
    and Quantitative Research teams

  o increasing the number of analysts supporting our portfolio managers and
    doubling the average investment experience of our domestic equity analyst
    staff

  o making additional use of our most-seasoned portfolio managers to mentor
    research analysts

  o combining more quantitative, top-down risk control and security analysis
    with our traditional bottom-up research process

  o opening a research office in Mexico City to complement our existing staff
    in Boston, London, Singapore, and Tokyo

The effect of these enhancements, I believe, is evident in the 2004 performance
of our funds. For the 12 months ended December 31, 2004, 80% of MFS domestic
equity funds, 100% of MFS international equity funds, and 80% of MFS fixed-
income funds delivered results in the top half of their Lipper peer groups.

Our longer-term performance also benefited from our ongoing commitment to the
MFS Original Research(R) process: more than 75% of MFS funds were in the top
half of their respective Lipper categories over the 3-, 5-, and 10-year
periods ended December 31, 2004.

Of course, I cannot offer any guarantees that our performance will repeat
itself. Still, I am confident that the recent enhancements to our investment
process will continue to benefit shareholders in 2005 and beyond.

What I can tell you with certainty is that the way you manage your investments
will determine how well you take advantage of the performance that financial
markets deliver. Historically, individual investors have tended to underperform
the markets. For example, a 2003 study by DALBAR, Inc. showed that over the
nearly two decades from 1984 through 2002, the average U.S. stock investor
earned a 2.6% average annual return at a time when U.S. stocks, as measured by
the Standard & Poor's 500 Stock Index, delivered a 12.2% average annual
return.(1)

This huge discrepancy, in our view, occurred because nonprofessional investors
generally did not adhere to the basic principles followed by most professional
investors: allocate among asset classes, diversify within each asset class, and
rebalance one's portfolio on a routine schedule. I elaborated on this "ADR"
theme in fund reports over the last few months of 2004. For more information on
how to apply a Disciplined Diversification(SM) strategy to your portfolio using
the principles of ADR, I would urge you to contact your own investment
professional. You may also want to refer to information on the subject on our
Web site, MFS.COM.

As always, we appreciate your confidence in MFS, and you can be sure of our
continued commitment to do the best we can to help you pursue your long-term
financial goals.

    Respectfully,

/s/ Robert J. Manning

MANAGEMENT REVIEW
- -------------------------------------------------------------------------------

SUMMARY OF RESULTS

For the six months ended February 28, 2005, the MFS Money Market Fund provided
a total return of 0.83%. At period-end, the fund's seven-day yields with and
without waiver were 1.88% and 1.59%, respectively. The yield quotation is based
on the latest seven days ended with dividends annualized, and more closely
reflects the fund's current earnings than does the total return quotation. The
fund's investment objective is to seek as high a level of current income as is
considered consistent with the preservation of capital and liquidity. The fund
invests in U.S. dollar denominated money market instruments such as, U.S.
government securities, repurchase agreements collateralized by U.S. government
securities, certificates of deposit, bankers' acceptances and other bank
obligations, commercial paper, and other short-term obligations.

For the same period, the MFS Government Money Market Fund provided a total
return of 0.79%. At period-end, the fund's seven-day yields with and without
waiver were 2.02% and 1.67%, respectively. The fund's investment objective is
to seek as high a level of current income as is considered consistent with the
preservation of capital and liquidity. Under normal market conditions, the fund
invests at least 80% of its net assets in U.S. government securities, U.S.
Treasury obligations, and obligations issued or guaranteed by U.S. government
agencies, authorities or instrumentalities.

FACTORS IMPACTING PERFORMANCE

For the period as a whole, the U.S. yield curve flattened as interest rates on
the short end of the curve moved up while rates on the long end were flat to
down.

During the period, we maintained our weighted average maturity positions for
both funds, ending the period with a maturity of 33 days for MFS Money Market
Fund and 30 days for MFS Government Money Market Fund. Essentially, we
positioned the portfolios in such a way as to minimize our interest rate risk
as we anticipated that short-term rates would continue to rise for some time.

FUND POSITIONING

As of February 28, 2005, approximately 87% of the MFS Money Market Fund's net
assets were invested in high-quality commercial paper. The balance of the
portfolio was invested in repurchase agreements collateralized by U.S.
government agency notes, certificates of deposit, and discount agency notes.

At period-end, approximately 80% of the MFS Government Money Market Fund's net
assets were invested in U.S. government securities and obligations issued or
guaranteed by U.S. government agencies, authorities or instrumentalities. The
balance of the portfolio was invested in repurchase agreements collateralized
by U.S. government agency notes.

necessarily reflect the views of MFS or any other person in the MFS
organization. These views are subject to change at any time based on market and

- -------------------------------------------------------------------------------
PERFORMANCE SUMMARY THROUGH 2/28/05
- -------------------------------------------------------------------------------

Because mutual funds are designed for investors with long-term goals, we have
provided total returns as well as the current 7-day yield for the applicable
time periods. Performance results reflect the percentage change in net asset
value, including the reinvestment of any dividends and capital gains
distributions. (See Notes to Performance Summary.)

An investment in either of the funds is not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency. Although
the funds seek to preserve the value of your investment at $1.00 per share, it
is possible to lose money by investing in either of these funds.

current earnings of the portrfolios than a total return quotation would.

NOTES TO PERFORMANCE SUMMARY

Shares of the funds can be purchased at net asset value without a sales charge.

Unless otherwise indicated, performance results reflect any applicable expense
subsidies and waivers in effect during the periods shown. Subsidies and fee
waivers may be imposed to enhance a portfolio's yield during periods when the
portfolio's operating expenses have a significant impact on the portfolio's
yield due to lower interest rates. Without such subsidies and waivers the
portfolio's performance results would be less favorable. Please see the
prospectus and financial statements for complete details.

KEY RISK CONSIDERATIONS

MFS(R) MONEY MARKET FUND

Money market instruments provide opportunities for income with low credit risk,
but may result in a lower yield than would be available from debt obligations
of a lower quality or longer term. Investors should note that while securities
issued by certain U.S. government agencies or instrumentalities are guaranteed
by the U.S. government, securities issued by many U.S. government agencies are
not guaranteed by the U.S. government.

The portfolio may invest in foreign and/or emerging markets securities, which
are more susceptible to interest rate, currency exchange rate, economic, and
political risks.

The portfolio may invest in municipal bonds that are general obligations backed
by the full faith and credit of the municipal issuer. The portfolio may also
invest in municipal bonds called revenue obligations which are subject to a
higher degree of credit risk than general obligations. The prices of these
securities will decline when interest rates rise and increase when rates fall.
In addition, municipal securities are subject to credit (failure to make timely
principal or interest payments) and maturity (longer maturity dates increase
security price fluctuations) risks.

MFS(R) GOVERNMENT MONEY MARKET FUND

Money market instruments provide opportunities for income with low credit risk,
but may result in a lower yield than would be available from debt obligations
of a lower quality or longer term. Investors should note that while securities
issued by certain U.S. government agencies or instrumentalities are guaranteed
by the U.S. government, securities issued by many U.S. government agencies are
not guaranteed by the U.S. government.

As with any fixed-income security, securities issued by certain U.S. government
agencies or instrumentalities are subject to the risk that the issuer will
default on principal and interest payments. It may be difficult to enforce
rights against the assets underlying these securities in the case of default.
Investors should note that many U.S. government securities in which the fund
may invest are not supported by the full faith and credit of the United States
Government (including securities issued by government sponsored enterprises and
by certain U.S. federal agencies and instrumentalities) and involve increased
credit risk.

Please see the prospectus for further information regarding these and other
risk considerations.

EXPENSE TABLES    MFS(R) MONEY MARKET FUND
                  MFS(R) GOVERNMENT MONEY MARKET FUND
- -------------------------------------------------------------------------------

FUND EXPENSES BORNE BY SHAREHOLDERS DURING THE PERIOD,
SEPTEMBER 1, 2004, THROUGH FEBRUARY 28, 2005.

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. This example is 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.

The example is based on an investment of $1,000 invested at the beginning
of the period and held for the entire period, September 1, 2004 through
February 28, 2005.

ACTUAL EXPENSES

The first line of the tables on the following page 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 of the tables on the following page 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 funds' 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 funds 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 of the table is
useful in comparing 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.

 * 5% fund return per year before expenses.
** Expenses paid is equal to each fund's annualized expense ratio for the most

   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 STATEMENTS           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, if shorter, the period of the fund's operation). 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 (assuming reinvestment of all distributions) held for the entire period.

NOTES TO FINANCIAL STATEMENTS (unaudited)
- -------------------------------------------------------------------------------

(1) BUSINESS AND ORGANIZATION

MFS Money Market Fund and MFS Government Money Market Fund (the funds) are each
a diversified series of MFS Series Trust IV (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.

INVESTMENT VALUATIONS - Money market instruments are valued at amortized cost,
which the Trustees have determined in good faith approximates market value.
Each fund's use of amortized cost is subject to the funds' compliance with
certain conditions as specified under Rule 2a-7 of the Investment Company Act
of 1940.

REPURCHASE AGREEMENTS - Each fund may enter into repurchase agreements with
institutions that the funds' investment adviser has determined are
creditworthy. Each repurchase agreement is recorded at cost. Each fund requires
that the securities collateral in a repurchase transaction be transferred to
the custodian in a manner sufficient to enable the fund to obtain those
securities in the event of a default under the repurchase agreement. The funds
monitor, on a daily basis, the value of the collateral to ensure that its
value, including accrued interest, is greater than amounts owed to the funds
under each such repurchase agreement. The funds, along with other affiliated
entities of Massachusetts Financial Services Company (MFS), may utilize a joint
trading account for the purpose of entering into one or more repurchase
agreements.

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 and tax
reporting purposes in accordance with U.S. generally accepted accounting
principles and federal tax regulations, respectively.

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 the
fund. These amounts, for the six months ended February 28, 2005, are shown as a
reduction of total expenses on each fund's Statement of Operations.

TAX MATTERS AND DISTRIBUTIONS - Each 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 taxable
income, including any net realized gain on investments. Accordingly, no
provision for federal income or excise tax is provided.

Distributions to shareholders are recorded on the ex-dividend date. The funds
distinguish between distributions on a tax basis and a financial reporting
basis and 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.

The tax character of distributions declared for the years ended August 31, 2004
and August 31, 2003 was as follows:

                                                               GOVERNMENT MONEY

Distributions declared

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

As of August 31,2004, the components of distributable earnings (accumulated
losses) on a tax basis were as follows:

                                                              GOVERNMENT MONEY

Other temporary differences                  72,173                     (9,922)
- ------------------------------------------------------------------------------

For federal income tax purposes, the capital loss carryforward may be applied
against any net taxable realized gains of each succeeding year until the
earlier of its utilization or expiration on August 31, 2011 for the MFS Money
Market Fund.

(3) TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISER - Each fund has an investment advisory agreement with
Massachusetts Financial Services Company (MFS) to provide overall investment
advisory and administrative services, and general office facilities.

Each fund's management fee is computed daily and paid monthly at the following
annual rates:

          First $300 million of average net assets             0.50%
          ----------------------------------------------------------
          Next $400 million of average net assets              0.45%
          ----------------------------------------------------------
          Next $300 million of average net assets              0.40%
          ----------------------------------------------------------
          Average net assets in excess of $1 billion           0.35%
          ----------------------------------------------------------

As part of a settlement agreement with the New York Attorney General concerning
market timing and related matters (See Legal Proceedings footnote), MFS has
agreed to reduce each fund's management fee to 0.15% of average daily net
assets for the period March 1, 2004 through February 28, 2009, which is shown
as a reduction of total expenses in the Statement of Operations. During this
time period, the Board of Trustees will continue to review the appropriateness
of all advisory fees in accordance with their oversight responsibilities. After
February 28, 2009 the management fee will be determined in accordance with then
existing review policies approved by the Board of Trustees overseeing the fund.

Management fees incurred for the six months ended February 28, 2005 were an
effective rate of 0.15% of average daily net assets on an annualized basis for
each fund.

The funds pay compensation to their Independent Trustees in the form of a
retainer, attendance fees, and additional compensation to Board and Committee
chairpersons, and pay no compensation directly to their Trustees who are
officers of the investment adviser, or to officers of the funds, all of whom
receive remuneration for their services to the fund from MFS. Certain officers
and Trustees of the funds are officers or directors of MFS, MFS Fund
Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). The funds have
an unfunded defined benefit plan for retired Independent Trustees. Included in
Trustees' compensation is a pension expense of $2,954 and $582 for retired
Independent Trustees for the six months ended February 28, 2005 for the MFS
Money Market Fund and MFS Government Money Market Fund, respectively.

These funds 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. MFS has agreed to
reimburse each of the funds for a proportional share of substantially all of
the payments made by the funds to Tarantino LLC and also to provide office
space and other administrative support and supplies to the ICCO. The funds can
terminate the Agreement with Tarantino LLC at any time under the terms of the
Agreement.

ADMINISTRATOR - MFS provides certain financial, legal, shareholder
communications, compliance, and other administrative services to certain funds
for which MFS acts as investment adviser. Under an administrative services
agreement between the funds and MFS, MFS is entitled to partial reimbursement
of the costs MFS incurs to provide these services, subject to review and
approval by the Board of Trustees. Each fund is allocated a portion of these
administrative costs based on its size and relative average net assets. The
funds paid MFS an administrative fee up to the following annual percentage
rates of the funds' average daily net assets:

                                              9/01/04
                                              THROUGH
EFFECTIVE DATE                                2/28/05                3/01/05

First $2 billion                              0.01120%              0.01626%
- ----------------------------------------------------------------------------
Next $2.5 billion                             0.00832%              0.01206%
- ----------------------------------------------------------------------------
Next $2.5 billion                             0.00032%              0.00056%
- ----------------------------------------------------------------------------
In excess of $7 billion                       0.00000%              0.00000%
- ----------------------------------------------------------------------------

The March 1, 2005 rates were not effective during the current reporting period.
For the six months ended February 28, 2005, the MFS Money Market Fund and the
MFS Government Money Market Fund paid MFS $21,917 and $939, equivalent to
0.00556% and 0.00543% of average daily net assets, respectively, to partially
reimburse MFS for the costs of providing administrative services.

DISTRIBUTOR - Certain shares acquired through an exchange may be subject to a
CDSC upon redemption depending on when the shares exchanged were originally
purchased. Contingent deferred sales charges imposed during the six months
ended February 28, 2005 for the MFS Money Market Fund and MFS Government Money
Market Fund were $2,219 and $0, respectively.

SHAREHOLDER SERVICING AGENT - Included in shareholder servicing costs is a fee
paid to MFSC, a wholly owned subsidiary of MFS, for its services as shareholder
servicing agent. The fee, which is calculated as a percentage of the funds'
average daily net assets is set periodically under the supervision of the
funds' Trustees. For the period September 1, 2004 through December 31, 2004,
each fund was charged up to 0.0861% of its average daily net assets. For the
period January 1, 2005 through February 28, 2005, each fund was charged up to
0.1035% of its average daily net assets. For the six months ended February 28,
2005, the funds paid MFSC a fee of $352,543 and $15,368 for shareholder
services which equated to 0.0894% and 0.0889% of the average daily net assets
for the MFS Money Market Fund and MFS Government Money Market Fund,
respectively. Effective March 1, 2005, each fund is charged up to 0.1159% of
its average daily net assets. Shareholder service costs include out of pocket
expenses and sub accounting services expenses paid by MFSC on behalf of the
funds and subsequently reimbursed to MFSC which amounted to $158,105 and $3,412
for the MFS Money Market Fund and the MFS Government Money Market Fund,
respectively, and other costs paid by the funds directly to unaffiliated
vendors for the six months ended February 28, 2005.

(4) PORTFOLIO SECURITIES

Purchases and sales of money market investments, exclusive of securities
subject to repurchase agreements, for MFS Money Market Fund aggregated
$6,061,137,698 and $6,166,997,127 respectively.

Purchases and sales of money market investments, exclusive of securities
subject to repurchase agreements, for MFS Government Money Market Fund
aggregated $229,511,546 and $231,576,000 respectively.

(5) SHARES OF BENEFICIAL INTEREST

Each fund's Declaration of Trust permits the Trustees to issue an unlimited
number of full and fractional shares of beneficial interest.

The MFS Money Market Fund is one of several MFS mutual funds in which the MFS
Asset Allocation Funds may invest. The MFS Asset Allocation Funds do not invest
in the underlying MFS funds for the purpose of exercising management or
control. At the end of the period, the MFS Conservative Allocation Fund and MFS
Moderate Allocation Fund were the owners of record of approximately 7% and 10%,
respectively, of the total outstanding shares.

(6) LINE OF CREDIT

The funds and other affiliated funds participate in an $800 million unsecured
line of credit provided by a syndication of banks under a line of credit
agreement. Borrowings may be made for temporary financing needs. Interest is
charged to each fund, based on its borrowings, at a rate equal to the Federal
Reserve funds rate plus 0.50%. 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 calendar quarter. The commitment fee
allocated to the MFS Money Market Fund and MFS Government Money Market Fund for
the six months ended February 28, 2005 was $2,405 and $86 respectively and is
included in miscellaneous expense. The funds had no significant borrowings
during the six months ended February 28, 2005.

(7) LEGAL PROCEEDINGS

On March 31, 2004, MFS settled an administrative proceeding with the Securities
and Exchange Commission ("SEC") regarding disclosure of brokerage allocation
practices in connection with MFS fund sales (the term "MFS funds" means the
open-end registered management investment companies sponsored by MFS). Under
the terms of the settlement, in which MFS neither admitted nor denied any
wrongdoing, MFS agreed to pay (one dollar) $1.00 in disgorgement and $50
million in penalty to certain MFS funds, pursuant to a plan developed by an
independent distribution consultant. The brokerage allocation practices which
were the subject of this proceeding were discontinued by MFS in November 2003.
The agreement with the SEC is reflected in an order of the SEC. The SEC
settlement order states that MFS failed to adequately disclose to the Boards of
Trustees and to shareholders of the MFS funds the specifics of its preferred
arrangements with certain brokerage firms selling MFS fund shares. The SEC
settlement order states that MFS had in place policies designed to obtain best
execution of all MFS fund trades. As part of the settlement, MFS retained an
independent compliance consultant to review the completeness of its current
policies and practices regarding disclosure to MFS fund trustees and to MFS
fund shareholders of strategic alliances between MFS or its affiliates and
broker-dealers and other financial intermediaries who support the sale of MFS
fund shares. Pursuant to the SEC order, on July 28, 2004, MFS transferred these
settlement amounts to the SEC, and those MFS funds entitled to these settlement
amounts accrued an estimate of their pro rata portion of these amounts. The
final distribution plan was approved by the SEC on January 21, 2005 and the
affected MFS funds received the payment on February 16, 2005.

In addition, in February, 2004, MFS reached agreement with the SEC, the New
York Attorney General ("NYAG") and the Bureau of Securities Regulation of the
State of New Hampshire ("NH") to settle administrative proceedings alleging
false and misleading information in certain MFS open-end retail fund ("MFS
retail funds") prospectuses regarding market timing and related matters (the
"February Settlements"). These regulators alleged that prospectus language for
certain MFS retail funds was false and misleading because, although the
prospectuses for those funds in the regulators' view indicated that they
prohibited market timing, MFS did not limit trading activity in 11 domestic
large cap stock, high grade bond and money market retail funds. MFS' former
Chief Executive Officer and former President also reached agreement with the
SEC in which they agreed to, among other terms, monetary fines and temporary
suspensions from association with any investment adviser or registered
investment company. These individuals have resigned their positions with, and
will not be returning to, MFS and the MFS funds. Under the terms of the
February Settlements, MFS and the executives neither admit nor deny wrongdoing.

Under the terms of the February Settlements, a $225 million pool has been
established for distribution to shareholders in certain MFS retail funds, which
has been funded by MFS and of which $50 million is characterized as a penalty.
This pool will be distributed in accordance with a methodology developed by an
independent distribution consultant in consultation with MFS and the Board of
Trustees of the MFS retail funds, and acceptable to the SEC. MFS has further
agreed with NYAG to reduce its management fees in the aggregate amount of
approximately $25 million annually over the next five years, and not to
increase certain management fees during this period. MFS has also paid an
administrative fine to NH in the amount of $1 million, which will be used for
investor education purposes (NH retained $250,000 and $750,000 was contributed
to the North American Securities Administrators Association's Investor
Protection Trust). In addition, under the terms of the February Settlements,
MFS is in the process of adopting certain governance changes and reviewing its
policies and procedures.

Since December 2003, MFS, MFS Fund Distributors, Inc., MFS Service Center,
Inc., MFS Corporation Retirement Committee, Sun Life Financial Inc., various
MFS funds, certain current and/or former Trustees of these MFS funds, and
certain officers of MFS have been named as defendants in multiple lawsuits
filed in federal and state courts. The lawsuits variously have been commenced
as class actions or individual actions on behalf of investors who purchased,
held or redeemed shares of the MFS funds during specified periods, as ERISA
actions by participants in certain retirement plan accounts on behalf of those
accounts, or as derivative actions on behalf of the MFS funds. The lawsuits
relating to market timing and related matters have been transferred to, and
consolidated before, the United States District Court for the District of
Maryland, as part of a multi-district litigation of market timing and related
claims involving several other fund complexes (In re Mutual Funds Investment
Litigation (Alger, Columbia, Janus, MFS, One Group, Putnam, Allianz Dresdner),
No. 1:04-md-15863 (transfer began March 19, 2004)). The market timing cases
related to the MFS complex are Riggs v. MFS et al., Case No. 04-cv-01162-JFM
(direct), Hammerslough v. MFS et al., Case No. 04-md-01620 (derivative) and
Anita Walker v. MFS et al., Case No. 1:04-CV-01758 (ERISA). The plaintiffs in
these consolidated lawsuits generally seek injunctive relief including removal
of the named Trustees, adviser and distributor, rescission of contracts and
12b-1 Plans, disgorgement of fees and profits, monetary damages, punitive
damages, attorney's fees and costs and other equitable and declaratory relief.
Two lawsuits alleging improper brokerage allocation practices and excessive
compensation are pending in the United States District Court for the District
of Massachusetts (Forsythe v. Sun Life Financial Inc., et al., No. 04cv10584
(GAO) (a consolidated action) and Marcus Dumond, et al. v. Massachusetts
Financial Servs. Co., et al., No. 04cv11458 (GAO)). The plaintiffs in these
lawsuits generally seek compensatory damages, punitive damages, recovery of
fees, rescission of contracts, an accounting, restitution, declaratory relief,
equitable and/or injunctive relief and attorney's fees and costs. The various
lawsuits generally allege that some or all of the defendants (i) permitted or
acquiesced in market timing and/or late trading in some of the MFS funds,
inadequately disclosed MFS' internal policies concerning market timing and such
matters (ii) received excessive compensation as fiduciaries to the MFS funds,
or (iii) permitted or acquiesced in the improper use of fund assets by MFS to
support the distribution of MFS fund shares and inadequately disclosed MFS' use
of fund assets in this manner. The actions assert that some or all of the
defendants violated the federal securities laws, including the Securities Act
of 1933 and the Securities Exchange Act of 1934, the Investment Company Act of
1940 and the Investment Advisers Act of 1940, the Employee Retirement Income
Security Act of 1974, as well as fiduciary duties and other violations of
common law. Insofar as any of the actions is appropriately brought derivatively
on behalf of any of the MFS funds, any recovery will inure to the benefit of
the MFS funds. The defendants are reviewing the allegations of the multiple
complaints and will respond appropriately. Additional lawsuits based on similar
allegations may be filed in the future.

Any potential resolution of these matters may include, but not be limited to,
judgments or settlements for damages against MFS, the MFS funds, or any other
named defendant. As noted above, as part of the regulatory settlements, MFS has
established a restitution pool in the amount of $225 million to compensate
certain shareholders of certain MFS retail funds for damages that they
allegedly sustained as a result of market timing or late trading in certain of
the MFS retail funds, and distributed $50 million to affected MFS funds to
compensate those funds based upon the amount of brokerage commissions allocated
in recognition of MFS fund sales. It is not clear whether these amounts will be
sufficient to compensate shareholders for all of the damage they allegedly
sustained, whether certain shareholders or putative class members may have
additional claims to compensation, or whether the damages that may be awarded
in any of the actions will exceed these amounts. In the event the MFS funds
incur any losses, costs or expenses in connection with such lawsuits, the
Boards of Trustees of the affected MFS funds may pursue claims on behalf of
such funds against any party that may have liability to the funds in respect
thereof.

Review of these matters by the independent Trustees of the MFS funds and their
counsel is continuing. There can be no assurance that these regulatory actions
and lawsuits, or the adverse publicity associated with these developments, will
not result in increased fund redemptions, reduced sales of fund shares, or
other adverse consequences to the MFS funds.

LETTER FROM THE CEO
- -------------------------------------------------------------------------------

Dear Shareholders,

[Photo of Robert J. Manning]

Last summer and fall, I wrote to you about enhancements that MFS(R) was making
to its investment process. Our goal, as always, was to deliver strong
performance across all asset classes. I am now happy to report to you that
2004 was a very successful year for MFS, relative to our peers in the mutual
fund industry. While there will always be room for improvement, we believe the
enhancements we have made to our investment process resulted in significantly
improved performance across the MFS Family of Funds(R).

You may remember some of the enhancements I outlined last year. They included

  o increasing collaboration and information sharing among our investment
    personnel across asset classes, through an Investment Management Committee
    with members from our Domestic Equity, International Equity, Fixed Income,
    and Quantitative Research teams

  o increasing the number of analysts supporting our portfolio managers and
    doubling the average investment experience of our domestic equity analyst
    staff

  o making additional use of our most-seasoned portfolio managers to mentor
    research analysts

  o combining more quantitative, top-down risk control and security analysis
    with our traditional bottom-up research process

  o opening a research office in Mexico City to complement our existing staff
    in Boston, London, Singapore, and Tokyo

The effect of these enhancements, I believe, is evident in the 2004 performance
of our funds. For the 12 months ended December 31, 2004, 80% of MFS domestic
equity funds, 100% of MFS international equity funds, and 80% of MFS fixed-
income funds delivered results in the top half of their Lipper peer groups.

Our longer-term performance also benefited from our ongoing commitment to the
MFS Original Research(R) process: more than 75% of MFS funds were in the top
half of their respective Lipper categories over the 3-, 5-, and 10-year periods
ended December 31, 2004.

Of course, I cannot offer any guarantees that our performance will repeat
itself. Still, I am confident that the recent enhancements to our investment
process will continue to benefit shareholders in 2005 and beyond.

What I can tell you with certainty is that the way you manage your investments
will determine how well you take advantage of the performance that financial
markets deliver. Historically, individual investors have tended to underperform
the markets. For example, a 2003 study by DALBAR, Inc. showed that over the
nearly two decades from 1984 through 2002, the average U.S. stock investor
earned a 2.6% average annual return at a time when U.S. stocks, as measured by
the Standard & Poor's 500 Stock Index, delivered a 12.2% average annual
return.(1)

This huge discrepancy, in our view, occurred because nonprofessional investors
generally did not adhere to the basic principles followed by most professional
investors: allocate among asset classes, diversify within each asset class, and
rebalance one's portfolio on a routine schedule. I elaborated on this "ADR"
theme in fund reports over the last few months of 2004. For more information on
how to apply a Disciplined Diversification(SM) strategy to your portfolio using
the principles of ADR, I would urge you to contact your own investment
professional. You may also want to refer to information on the subject on our
Web site, MFS.COM.

As always, we appreciate your confidence in MFS, and you can be sure of our
continued commitment to do the best we can to help you pursue your long-term
financial goals.

    Respectfully,

/s/ Robert J. Manning

    Chief Executive Officer and Chief Investment Officer

MANAGEMENT REVIEW
- -------------------------------------------------------------------------------

SUMMARY OF RESULTS

For the six months ended February 28, 2005, Class A shares of the MFS Mid Cap
Growth Fund provided a total return of 12.93%, not including sales charges. In
comparison, the fund's benchmark, the Russell MidCap Growth Index, returned
17.94%. The fund's investment objective is long-term growth of capital. The
fund invests, under normal market conditions, at least 80% of its net assets in
common stocks and related securities, such as preferred stocks, convertible
securities and depositary receipts for those securities, of companies with
medium market capitalizations which MFS believes have reasonable valuations and
above-average growth potential.

MARKET ENVIRONMENT

Over the period, many measures of global economic growth, including employment
and corporate spending, continued to improve, although we feel that high oil
prices, rising short-term interest rates in the United States, a significant
decline in the value of the U.S. dollar against most major currencies, and
geopolitical uncertainty, impacted markets. But, oil prices pulled back from
their record levels toward the end of 2004 and, in our view, investors seemed
to turn their attention to strong corporate profits and economic growth.

DETRACTORS FROM PERFORMANCE

Stock selection and an overweighted position in the health care sector held
back relative performance. Medical testing company Cytyc Corp., drug company
Medicis Pharmaceutical, medical technology company Millipore, and biotech firms
Genzyme and Gilead Sciences, which is not in the index, were among the fund's
top detractors for the period.

Stock selection in the leisure sector also dampened relative returns. Citadel
Broadcasting was among the fund's top detractors. Stock selection and an
underweighted position in the energy sector also hurt investment results. Our
decision not to hold strong performing XTO Energy, which is in the index,
detracted from relative returns.

Stocks in other sectors that held back relative performance included personal
computer maker Apple Computer and electric power company AES Corp., both
strong-performing companies that we did not own. Our overweight position in
poor-performing JetBlue Airways also hurt performance.

CONTRIBUTORS TO PERFORMANCE

In the financial services sector, strong stock selection provided the greatest
contribution to the portfolio's overall relative performance. Legg Mason was
among the fund's top contributors for the period.

Not holding any stocks in the consumer staples sector boosted relative results,
as the sector underperformed the benchmark.

Stock selection in the basic materials sector also helped the fund's relative
performance. Our position in strong performing agribusiness firm Monsanto,
which is not in the index, aided results. Stocks in other sectors that
contributed to relative returns included technology companies Amdocs, F5
Networks*, and Marvell Technology, which are not in the index, Comverse
Technology, and VERITAS Software. Our overweighted positions in Monster
Worldwide and SpectraSite, an owner and operator of wireless towers, and our
avoidance of health care company Biomet, also helped boost relative
performance.

* Effective April 1, 2005, Class R1 shares have been renamed "Class R shares,"
  and Class R2 shares have been renamed "Class R3 shares." In addition, on
  April 1, 2005, the fund launched the following new R Classes: R1, R2, R4, and
  R5. All references herein to Class R1 and Class R2 shares are as of February
  28, 2005 and do not reflect the renaming of Class R1 and Class R2 shares.

INDEX DEFINITION

Russell MidCap Growth Index - is constructed to provide a comprehensive
barometer for the growth securities in the mid-cap segment of the U.S. equity
universe. Companies in this index generally have higher price-to-book ratios
and higher forecasted growth values.

It is not possible to invest directly in an index.

NOTES TO PERFORMANCE SUMMARY

Class A and 529A results including sales charge reflect the deduction of the
maximum 5.75% sales charge. Class B and 529B results including sales charge
reflect the deduction of the applicable contingent deferred sales charge
(CDSC), which declines over six years from 4% to 0%. Class C and 529C results
including sales charge (assuming redemption within one year from the end of the
prior month of purchase) reflect the deduction of the 1% CDSC. Class I shares
have no sales charges and are available only to certain investors. Class R1 and
R2 shares have no sales charges and are available only to certain retirement
plans. Class 529A, 529B, 529C shares are only available in conjunction with
qualified tuition programs, such as the MFS 529 Savings Plan. There also is an
additional annual fee, which is detailed in the program description, on
qualified tuition programs. If this fee was reflected, the performance for
Class 529 shares would have been lower. This annual fee is waived for Oregon
residents and for those accounts with assets of $25,000 or more.

Performance for I, R1 and 529A shares includes the performance of the fund's
Class A shares for periods prior to their offering. Performance for R2 and 529B
shares includes the performance of the fund's Class B shares for periods prior
to their offering. Performance for Class 529C shares includes the performance
of the fund's Class C shares for periods prior to their offering. This blended
class performance has been adjusted to take into account differences in sales
loads, if any, applicable to these share classes, but has not been adjusted to
take into account differences in class specific operating expenses (such as
Rule 12b-1 fees). Compared to performance these share classes would have
experienced had they been offered for the entire period, the use of blended
performance generally results in higher performance for share classes with
higher operating expenses than the share class to which it is blended, and
lower performance for share classes with lower operating expenses than the
share class to which it is blended.

Performance results reflect any applicable expense subsidies and waivers in
effect during the periods shown. Without such subsidies and waivers the fund's
performance results would be less favorable. Please see the prospectus and
financial statements for complete details.

The performance shown reflects a non-recurring accrual made to the fund on
July 28, 2004, relating to MFS' revenue sharing settlement with the Securities
and Exchange Commission, without which the performance would have been lower.
The proceeds were paid to the fund on February 16, 2005.

From time to time the fund may receive proceeds from litigation settlements,
without which performance would be lower.

KEY RISK CONSIDERATIONS

The portfolio may invest in foreign and/or emerging markets securities, which
are more susceptible to risks relating to interest rates, currency exchange
rates, economic, and political conditions.

The portfolio may invest in small-, mid-sized, or emerging companies, which are
susceptible to greater risk than is customarily associated with investing in
more established companies.

The portfolio has engaged and may engage in active and frequent trading to
achieve its principal investment strategies. This may result in the realization
and distribution to shareholders of higher capital gains, as compared to a
portfolio with less active trading policies, which would increase your tax
liability unless you hold your shares through a tax-deferred vehicle (such as
an IRA account). Frequent trading also increases transaction costs, which could
detract from the portfolio's performance.

Over-the-counter (OTC) transactions involve risks in addition to those
associated with transactions in securities traded on exchanges. OTC-listed
companies may have limited product lines, markets or financial resources. Many
OTC stocks trade less frequently and in smaller volume than exchange-listed
stocks. The values of these stocks may be more volatile than exchange-listed
stocks, and the portfolio may experience difficulty in buying and selling these
stocks at prevailing market prices.

The portfolio utilizes short sales as an investment technique and will suffer a
loss if it sells a security short and the value of that security rises.

Please see the prospectus for further information regarding these and other
risk considerations.

EXPENSE TABLE
- -------------------------------------------------------------------------------

FUND EXPENSES BORNE BY SHAREHOLDERS DURING THE PERIOD FROM
SEPTEMBER 1, 2004, THROUGH FEBRUARY 28, 2005.

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, September 1, 2004 through February
28, 2005.

ACTUAL EXPENSES

The first line for each share class in the table below 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 table below 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.

 * 5% class return per year before expenses.

** Expenses paid is equal to each class' annualized expense ratio for the most
   recent six month period, 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 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, if shorter, the period of the fund's operation). 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 (assuming reinvestment of all distributions) held for the entire period.

(S) Effective June 7, 2004, the investment adviser has voluntarily agreed to reimburse the fund for its proportional share of
    substantially all of Independent Chief Compliance Officer service fees paid to Tarantino LLC. If this fee had been
    incurred by the fund, the net investment loss per share and the ratios would have been:

 ** The reimbursement impact per share amount and ratios were less than $0.01 and 0.01%, respectively.
  # Per share data are based on average shares outstanding.
 ## Ratios do not reflect reductions from fees paid indirectly.

(+) Total returns do not include the applicable sales charge. If the charge had been included, the results would have been
    lower.
  & From time to time the fund may receive proceeds from litigation settlements, without which performance would be lower. +
    Annualized. ++ Not annualized.
+++ Per share amount was less than $0.01.
^^  The fund's net asset value and total return calculation include a non- recurring accrual recorded as a result of an
    administrative proceeding regarding disclosure of brokerage allocation practices in connection with fund sales, as
    described in the Legal Proceedings and Transactions with Affiliates footnotes. The non-recurring accrual did not have a
    material impact on the net asset value per share based on the shares outstanding on the day the proceeds were recorded.
    The proceeds were paid to the fund on February 16, 2005.

NOTES TO FINANCIAL STATEMENTS (unaudited)
- -------------------------------------------------------------------------------

(1) BUSINESS AND ORGANIZATION

MFS Mid Cap Growth Fund (the fund) is a diversified series of MFS Series Trust
IV (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. The fund
can invest in foreign securities. Investments in foreign securities are
vulnerable to the effects of changes in the relative values of the local
currency and the U.S. dollar and to the effects of changes in each country's
legal, political, and economic environment.

INVESTMENT VALUATIONS - Equity securities in the fund's portfolio for which
market quotations are available are valued at the last sale or official closing
price as reported by an independent pricing service on the primary market or
exchange on which they are primarily traded, or at the last quoted bid price
for securities in which there were no sales during the day. Equity securities
traded over the counter are valued at the last sales price traded each day as
reported by an independent pricing service, or to the extent there are no sales
reported, such securities are valued on the basis of quotations obtained from
brokers and dealers. Short-term obligations with a remaining maturity in excess
of 60 days will be valued upon dealer-supplied valuations. All other short-term
obligations in the fund's portfolio are valued at amortized cost, which
approximates market value as determined by the Board of Trustees. Money market
mutual funds are valued at net asset value. Investment valuations, other
assets, and liabilities initially expressed in foreign currencies are converted
each business day into U.S. dollars based upon current exchange rates. When
pricing service information or market quotations are not readily available,
securities are priced at fair value as determined under the direction of the
Board of Trustees. For example, significant events (such as movement in the
U.S. securities market, or other regional and local developments) may occur
between the time that foreign markets close (where the security is principally
traded) and the time that the fund calculates its net asset value (generally,
the close of the NYSE) that may impact the value of securities traded in these
foreign markets. In these cases, the fund may utilize information from an
external vendor or other sources to adjust closing market quotations of foreign
equity securities to reflect what it believes to be the fair value of the
securities as of the fund's valuation time. Because the frequency of
significant events is not predictable, fair valuation of foreign equity
securities may occur on a frequent basis.

REPURCHASE AGREEMENTS - The fund may enter into repurchase agreements with
institutions that the fund's investment adviser has determined are
creditworthy. Each repurchase agreement is recorded at cost. The fund requires
that the securities collateral in a repurchase transaction be transferred to
the custodian in a manner sufficient to enable the fund to obtain those
securities in the event of a default under the repurchase agreement. The fund
monitors, on a daily basis, the value of the collateral to ensure that its
value, including accrued interest, is greater than amounts owed to the fund
under each such repurchase agreement. The fund, along with other affiliated
entities of Massachusetts Financial Services Company (MFS), may utilize a joint
trading account for the purpose of entering into one or more repurchase
agreements.

FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments,
income, and expenses are converted into U.S. dollars based upon currency
exchange rates prevailing on the respective dates of such transactions. Gains
and losses attributable to foreign currency exchange rates on sales of
securities are recorded for financial statement purposes as net realized gains
and losses on investments. Gains and losses attributable to foreign exchange
rate movements on income and expenses are recorded for financial statement
purposes as foreign currency transaction gains and losses. That portion of both
realized and unrealized gains and losses on investments that results from
fluctuations in foreign currency exchange rates is not separately disclosed.

SECURITY LOANS - State Street Bank and Trust Company ("State Street") and J.P.
Morgan Chase and Co. ("Chase"), as lending agents, may loan the securities of
the fund to certain qualified institutions (the "Borrowers") approved by the
fund. The loans are collateralized at all times by cash and/or U.S. Treasury
securities in an amount at least equal to the market value of the securities
loaned. State Street and Chase provide the fund with indemnification against
Borrower default. The fund bears the risk of loss with respect to the
investment of cash collateral. On loans collateralized by cash, the cash
collateral is invested in a money market fund or short-term securities. A
portion of the income generated upon investment of the collateral is remitted
to the Borrowers, and the remainder is allocated between the fund and the
lending agents. On loans collateralized by U.S. Treasury securities, a fee is
received from the Borrower, and is allocated between the fund and the lending
agents. The dividend and interest income earned on the securities loaned is
accounted for in the same manner as other dividend and interest income.

SHORT TERM FEES - For purchases made on or after July 1, 2004 and before April
1, 2005, the fund will charge a 2% redemption fee (which is retained by the
fund) on proceeds from Class A, Class B, Class C, and Class I shares redeemed
or exchanged within 5 business days following their acquisition (either by
purchase or exchange). Effective April 1, 2005, the fund will no longer charge
a redemption fee. See the fund's prospectus for details. Any redemption fees
charged are accounted for as an addition to paid-in capital.

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 discount is
accreted for tax reporting purposes as required by federal income tax
regulations. Dividends received in cash are recorded on the ex-dividend date.
Dividend and interest payments received in additional securities are recorded
on the ex-dividend or ex-interest date in an amount equal to the value of the
security on such date.

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.

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. During the six months ended February 28, 2005, the fund's custodian fees
were reduced by $19,352 under this arrangement. The fund has entered into a
commission recapture agreement, under which certain brokers will credit the
fund a portion of the commissions generated, to offset certain expenses of the
fund. For the six months ended February 28, 2005, the fund's miscellaneous
expenses were reduced by $23,822 under this agreement. These amounts are shown
as a reduction of total 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 taxable
income, including any net realized gain on investments. Accordingly, no
provision for federal income or excise tax is provided.

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 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. Common
types of book and tax differences that could occur include differences in
accounting for foreign currency transactions and capital losses.

The fund paid no distributions for the years ended August 31, 2004 and August
31, 2003.

As of August 31, 2004, the components of distributable earnings (accumulated
losses) on a tax basis were as follows:

          Capital loss carryforward                  $(1,625,034,484)
          ----------------------------------------------------------
          Unrealized appreciation                        111,026,643
          ----------------------------------------------------------
          Other temporary differences                        (90,665)
          ----------------------------------------------------------

For federal income tax purposes, the capital loss carryforward may be applied
against any net taxable realized gains of each succeeding year until the
earlier of its utilization or expiration as follows: on August 31, 2011, $
(1,625,034,484).

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 daily net
assets of each class, without distinction between share classes. Dividends are
declared separately for each class. Differences in per share dividend rates are
generally due to differences in separate class expenses. Class B and Class 529B
shares will convert to Class A and Class 529A shares, respectively,
approximately eight years after purchase.

(3) TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISER - The fund has an investment advisory agreement with
Massachusetts Financial Services Company (MFS) to provide overall investment
advisory and administrative services, and general office facilities. The
management fee is computed daily and paid monthly at an annual rate of 0.75% of
the fund's average daily net assets.

MFS has agreed to a voluntary reduction in its management fee to an annual rate
of 0.70% on net assets in excess of $3.0 billion. This fee reduction
arrangement may only be changed with approval by the Board of Trustees which
oversees the fund.

The fund pays compensation to its Independent Trustees in the form of a
retainer, attendance fees, and additional compensation to Board and Committee
chairpersons, and pays no compensation directly to its Trustees who are
officers of the investment adviser, or to officers of the fund, 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, MFS Fund
Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). The fund has an
unfunded, defined benefit plan for retired Independent Trustees and an unfunded
retirement benefit deferral plan for certain current Independent Trustees.
Included in Trustees' compensation is a net increase of $9,925 as a result of
the change in the fund's unfunded retirement benefit deferral plan for certain
current Independent Trustees and a pension expense of $1,399 for retired
Independent Trustees for the six months ended February 28, 2005.

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. MFS has agreed to
reimburse each of the funds for a proportional share of substantially all of
the payments made by the funds to Tarantino LLC and also to provide office
space and other administrative support and supplies to the ICCO. The funds can
terminate the Agreement with Tarantino LLC at any time under the terms of the
Agreement.

The fund's investment adviser, MFS, has been the subject of an administrative
proceeding regarding disclosure of brokerage allocation practices in connection
with fund sales, as described in the Legal Proceedings Footnote. On July 28,
2004, the fund accrued an estimate of the amount to be received pursuant to
this matter in the amount of $398,175, which did not have a material impact on
the net asset value per share based on the shares outstanding on the day the
proceeds were recorded. The proceeds were paid to the fund on February 16,
2005.

ADMINISTRATOR - MFS provides certain financial, legal, shareholder
communications, compliance, and other administrative services to certain funds
for which MFS acts as investment adviser. Under an administrative services
agreement between the funds and MFS, MFS is entitled to partial reimbursement
of the costs MFS incurs to provide these services, subject to review and
approval by the Board of Trustees. Each fund is allocated a portion of these
administrative costs based on its size and relative average net assets. The
fund paid MFS an administrative fee up to the following annual percentage rates
of the fund's average daily net assets:

                                            BEGINNING OF

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

The March 1, 2005 rates were not effective during the current reporting period.
For the six months ended February 28, 2005, the fund paid MFS $54,233
equivalent to 0.0054% of average daily net assets, to partially reimburse MFS
for the costs of providing administrative services.

In addition to the administrative services provided by MFS to the fund as
described above, MFS is responsible for providing certain administrative
services with respect to Class R2 shares. These services include various
administrative, recordkeeping, and communication/educational services with
respect to the retirement plans which invest in Class R2 shares, and may be
provided directly by MFS or by a third party. The fund pays an annual 0.25%
administrative service fee solely from the assets of Class R2 shares to MFS for
the provision of these services.

DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, as distributor, received
$38,542 and $317 for the six months ended February 28, 2005, as its portion of
the sales charge on sales of Class A and Class 529A shares of the fund,
respectively.

The Trustees have adopted a distribution plan for Class A, Class B, Class C,
Class R1, Class R2, Class 529A, Class 529B, and Class 529C 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 an annual
percentage of its average daily net assets attributable to certain share
classes as compensation for services provided by MFD and financial
intermediaries in connection with the distribution and servicing of its shares.
One component of the plan is a distribution fee and another is a service fee
paid by MFD to financial intermediaries that enter into sales or service
agreements with MFD or its affiliates based on the average daily net assets of
accounts attributable to such intermediaries. The fees are calculated based on
each class' average daily net assets. The maximum distribution and service fees
for each class of shares are as follows:

                           CLASS A     CLASS B     CLASS C  CLASS R1  CLASS R2

Distribution Fee             0.10%       0.75%       0.75%     0.25%     0.25%

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

MFD may retain all or a rtion of the service fee, including for accounts for
which there is no financial intermediary of record. Service fees retained by
MFD for the six months ended February 28, 2005 amounted to:

                             CLASS A    CLASS B    CLASS C  CLASS R1  CLASS R2

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

Payment of the 0.10% per annum Class A distribution fee will be implemented on
such date as the Trustees of the Trust may determine. Payment of the 0.15% per
annum portion of the Class 529A distribution fee that is not currently being
charged will be implemented on such date as the Trustees of the Trust may
determine. The Class A service fee is currently being waived.

Fees incurred under the distribution plan during the six months ended February
28, 2005 were as follows:

                             CLASS A    CLASS B    CLASS C  CLASS R1  CLASS R2

Certain Class A, Class C and Class 529C shares are subject to a contingent
deferred sales charge in the event of a shareholder redemption within, for
Class A shares, 12 months following the purchase, and, for Class C and Class
529C shares, the first year of purchase. A contingent deferred sales charge is
imposed on shareholder redemptions of Class B and Class 529B 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 six months ended February 28, 2005 were as follows:

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

The fund has and may from time to time enter into contracts with program
managers and other parties which administer the tuition programs through which
an investment in the fund's 529 share classes is made. The fund has entered
into an agreement with MFD pursuant to which MFD receives an annual fee of up
to 0.35% from the fund based solely upon the value of the fund's 529 share
classes attributable to tuition programs to which MFD or a third party which
contracts with MFD provides administrative services. The current fee has been
established at 0.25% annually of average net assets of the fund's 529 share
classes attributable to such programs. The fee may only be increased with the
approval of the Board of Trustees that oversees the fund. The services provided
by MFD or a third party with which MFD contracts include recordkeeping and tax
reporting and account services, as well as services designed to maintain the
program's compliance with the Internal Revenue Code and other regulatory
requirements.

SHAREHOLDER SERVICING AGENT - Included in shareholder servicing costs is a fee
paid to MFSC, a wholly owned subsidiary of MFS, for its services as shareholder
servicing agent. The fee, which is calculated as a percentage of the fund's
average daily net assets is set periodically under the supervision of the
fund's Trustees. For the beginning of the period through December 31, 2004, the
fund was charged up to 0.0861% of its average daily net assets. For the period
January 1, 2005 through February 28, 2005, the fund is charged up to 0.1035% of
its average daily net assets. For the six months ended February 28, 2005, the
fund paid MFSC a fee of $903,237 for shareholder services which equated to
0.0902% of the fund's average daily net assets. Effective March 1, 2005, the
fund is charged up to 0.1159% of its average daily net assets. Shareholder
service costs include out of pocket expenses and sub accounting services
expenses paid by MFSC on behalf of the fund and subsequently reimbursed to MFSC
which amounted to $697,912, and other costs paid by the fund directly to
unaffiliated vendors for the six months ended February 28, 2005.

(4) PORTFOLIO SECURITIES

Purchases and sales of investments, other than U.S. government securities,
purchased option transactions, and short-term obligations, aggregated
$549,005,532 and $800,283,261, respectively.

* For the period from the inception of Class R2 shares, October 31, 2003, through August 31, 2004.


The fund is one of several MFS mutual funds in which the MFS Asset Allocation
Funds may invest. The MFS Asset Allocation Funds do not invest in the
underlying MFS funds for the purpose of exercising management or control. At
the end of the period, the MFS Moderate Allocation Fund, MFS Growth Allocation
Fund and MFS Aggressive Growth Allocation Fund were the owners of record of
approximately 4%, 8% and 5%, respectively, of the total outstanding shares.

(6) LINE OF CREDIT

The fund and other affiliated funds participate in an $800 million unsecured
line of credit provided by a syndication of banks under a line of credit
agreement. Borrowings may be made for temporary financing needs. Interest is
charged to each fund, based on its borrowings, at a rate equal to the Federal
Reserve funds rate plus 0.50%. 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 calendar quarter. The commitment fee
allocated to the fund for the six months ended February 28, 2005 was $6,345,
and is included in miscellaneous expense. The fund had no significant
borrowings during the six months ended February 28, 2005.

(7) LEGAL PROCEEDINGS

On March 31, 2004, MFS settled an administrative proceeding with the Securities
and Exchange Commission ("SEC") regarding disclosure of brokerage allocation
practices in connection with MFS fund sales (the term "MFS funds" means the
open-end registered management investment companies sponsored by MFS). Under
the terms of the settlement, in which MFS neither admitted nor denied any
wrongdoing, MFS agreed to pay (one dollar) $1.00 in disgorgement and $50
million in penalty to certain MFS funds, pursuant to a plan developed by an
independent distribution consultant. The brokerage allocation practices which
were the subject of this proceeding were discontinued by MFS in November 2003.
The agreement with the SEC is reflected in an order of the SEC. The SEC
settlement order states that MFS failed to adequately disclose to the Boards of
Trustees and to shareholders of the MFS funds the specifics of its preferred
arrangements with certain brokerage firms selling MFS fund shares. The SEC
settlement order states that MFS had in place policies designed to obtain best
execution of all MFS fund trades. As part of the settlement, MFS retained an
independent compliance consultant to review the completeness of its current
policies and practices regarding disclosure to MFS fund trustees and to MFS
fund shareholders of strategic alliances between MFS or its affiliates and
broker-dealers and other financial intermediaries who support the sale of MFS
fund shares. Pursuant to the SEC order, on July 28, 2004, MFS transferred these
settlement amounts to the SEC, and those MFS funds entitled to these settlement
amounts accrued an estimate of their pro rata portion of these amounts. The
final distribution plan was approved by the SEC on January 21, 2005 and the
affected MFS funds received the payment on February 16, 2005.

In addition, in February, 2004, MFS reached agreement with the SEC, the New
York Attorney General ("NYAG") and the Bureau of Securities Regulation of the
State of New Hampshire ("NH") to settle administrative proceedings alleging
false and misleading information in certain MFS open-end retail fund ("MFS
retail funds") prospectuses regarding market timing and related matters (the
"February Settlements"). These regulators alleged that prospectus language for
certain MFS retail funds was false and misleading because, although the
prospectuses for those funds in the regulators' view indicated that they
prohibited market timing, MFS did not limit trading activity in 11 domestic
large cap stock, high grade bond and money market retail funds. MFS' former
Chief Executive Officer and former President also reached agreement with the
SEC in which they agreed to, among other terms, monetary fines and temporary
suspensions from association with any investment adviser or registered
investment company. These individuals have resigned their positions with, and
will not be returning to, MFS and the MFS funds. Under the terms of the
February Settlements, MFS and the executives neither admit nor deny wrongdoing.

Under the terms of the February Settlements, a $225 million pool has been
established for distribution to shareholders in certain MFS retail funds, which
has been funded by MFS and of which $50 million is characterized as a penalty.
This pool will be distributed in accordance with a methodology developed by an
independent distribution consultant in consultation with MFS and the Board of
Trustees of the MFS retail funds, and acceptable to the SEC. MFS has further
agreed with NYAG to reduce its management fees in the aggregate amount of
approximately $25 million annually over the next five years, and not to
increase certain management fees during this period. MFS has also paid an
administrative fine to NH in the amount of $1 million, which will be used for
investor education purposes (NH retained $250,000 and $750,000 was contributed
to the North American Securities Administrators Association's Investor
Protection Trust). In addition, under the terms of the February Settlements,
MFS is in the process of adopting certain governance changes and reviewing its
policies and procedures.

Since December 2003, MFS, MFS Fund Distributors, Inc., MFS Service Center,
Inc., MFS Corporation Retirement Committee, Sun Life Financial Inc., various
MFS funds, certain current and/or former Trustees of these MFS funds, and
certain officers of MFS have been named as defendants in multiple lawsuits
filed in federal and state courts. The lawsuits variously have been commenced
as class actions or individual actions on behalf of investors who purchased,
held or redeemed shares of the MFS funds during specified periods, as ERISA
actions by participants in certain retirement plan accounts on behalf of those
accounts, or as derivative actions on behalf of the MFS funds. The lawsuits
relating to market timing and related matters have been transferred to, and
consolidated before, the United States District Court for the District of
Maryland, as part of a multi-district litigation of market timing and related
claims involving several other fund complexes (In re Mutual Funds Investment
Litigation (Alger, Columbia, Janus, MFS, One Group, Putnam, Allianz Dresdner),
No. 1:04-md-15863 (transfer began March 19, 2004)). The market timing cases
related to the MFS complex are Riggs v. MFS et al., Case No. 04-cv-01162-JFM
(direct), Hammerslough v. MFS et al., Case No. 04-md-01620 (derivative) and
Anita Walker v. MFS et al., Case No. 1:04-CV-01758 (ERISA). The plaintiffs in
these consolidated lawsuits generally seek injunctive relief including removal
of the named Trustees, adviser and distributor, rescission of contracts and
12b-1 Plans, disgorgement of fees and profits, monetary damages, punitive
damages, attorney's fees and costs and other equitable and declaratory relief.
Two lawsuits alleging improper brokerage allocation practices and excessive
compensation are pending in the United States District Court for the District
of Massachusetts (Forsythe v. Sun Life Financial Inc., et al., No. 04cv10584
(GAO) (a consolidated action) and Marcus Dumond, et al. v. Massachusetts
Financial Servs. Co., et al., No. 04cv11458 (GAO)). The plaintiffs in these
lawsuits generally seek compensatory damages, punitive damages, recovery of
fees, rescission of contracts, an accounting, restitution, declaratory relief,
equitable and/or injunctive relief and attorney's fees and costs. The various
lawsuits generally allege that some or all of the defendants (i) permitted or
acquiesced in market timing and/or late trading in some of the MFS funds,
inadequately disclosed MFS' internal policies concerning market timing and such
matters (ii) received excessive compensation as fiduciaries to the MFS funds,
or (iii) permitted or acquiesced in the improper use of fund assets by MFS to
support the distribution of MFS fund shares and inadequately disclosed MFS' use
of fund assets in this manner. The actions assert that some or all of the
defendants violated the federal securities laws, including the Securities Act
of 1933 and the Securities Exchange Act of 1934, the Investment Company Act of
1940 and the Investment Advisers Act of 1940, the Employee Retirement Income
Security Act of 1974, as well as fiduciary duties and other violations of
common law. Insofar as any of the actions is appropriately brought derivatively
on behalf of any of the MFS funds, any recovery will inure to the benefit of
the MFS funds. The defendants are reviewing the allegations of the multiple
complaints and will respond appropriately. Additional lawsuits based on similar
allegations may be filed in the future.

Any potential resolution of these matters may include, but not be limited to,
judgments or settlements for damages against MFS, the MFS funds, or any other
named defendant. As noted above, as part of the regulatory settlements, MFS has
established a restitution pool in the amount of $225 million to compensate
certain shareholders of certain MFS retail funds for damages that they
allegedly sustained as a result of market timing or late trading in certain of
the MFS retail funds, and distributed $50 million to affected MFS funds to
compensate those funds based upon the amount of brokerage commissions allocated
in recognition of MFS fund sales. It is not clear whether these amounts will be
sufficient to compensate shareholders for all of the damage they allegedly
sustained, whether certain shareholders or putative class members may have
additional claims to compensation, or whether the damages that may be awarded
in any of the actions will exceed these amounts. In the event the MFS funds
incur any losses, costs or expenses in connection with such lawsuits, the
Boards of Trustees of the affected MFS funds may pursue claims on behalf of
such funds against any party that may have liability to the funds in respect
thereof.

Review of these matters by the independent Trustees of the MFS funds and their
counsel is continuing. There can be no assurance that these regulatory actions
and lawsuits, or the adverse publicity associated with these developments, will
not result in increased fund redemptions, reduced sales of fund shares, or
other adverse consequences to the MFS funds.

LETTER FROM THE CEO
- --------------------------------------------------------------------------------

Dear Shareholders,

[Photo of Robert J. Manning]

Last summer and fall, I wrote to you about enhancements that MFS(R) was making
to its investment process. Our goal, as always, was to deliver strong
performance across all asset classes. I am now happy to report to you that 2004
was a very successful year for MFS, relative to our peers in the mutual fund
industry. While there will always be room for improvement, we believe the
enhancements we have made to our investment process resulted in significantly
improved performance across the MFS Family of Funds(R).

You may remember some of the enhancements I outlined last year.
They included

  o increasing collaboration and information sharing among our investment
    personnel across asset classes, through an Investment Management Committee
    with members from our Domestic Equity, International Equity, Fixed Income,
    and Quantitative Research teams

  o increasing the number of analysts supporting our portfolio managers and
    doubling the average investment experience of our domestic equity analyst
    staff

  o making additional use of our most-seasoned portfolio managers to mentor
    research analysts

  o combining more quantitative, top-down risk control and security analysis
    with our traditional bottom-up research process

    in Boston, London, Singapore, and Tokyo

The effect of these enhancements, I believe, is evident in the 2004 performance
of our funds. For the 12 months ended December 31, 2004, 80% of MFS domestic
equity funds, 100% of MFS international equity funds, and 80% of MFS fixed-
income funds delivered results in the top half of their Lipper peer groups.

Our longer-term performance also benefited from our ongoing commitment to the
MFS Original Research(R) process: more than 75% of MFS funds were in the top
half of their respective Lipper categories over the 3-, 5-, and 10-year periods
ended December 31, 2004.

Of course, I cannot offer any guarantees that our performance will repeat
itself. Still, I am confident that the recent enhancements to our investment
process will continue to benefit shareholders in 2005 and beyond.

What I can tell you with certainty is that the way you manage your investments
will determine how well you take advantage of the performance that financial
markets deliver. Historically, individual investors have tended to underperform
the markets. For example, a 2003 study by DALBAR, Inc. showed that over the
nearly two decades from 1984 through 2002, the average U.S. stock investor
earned a 2.6% average annual return at a time when U.S. stocks, as measured by
the Standard & Poor's 500 Stock Index, delivered a 12.2% average annual
return.(1)

This huge discrepancy, in our view, occurred because nonprofessional investors
generally did not adhere to the basic principles followed by most professional
investors: allocate among asset classes, diversify within each asset class, and
rebalance one's portfolio on a routine schedule. I elaborated on this "ADR"
theme in fund reports over the last few months of 2004. For more information on
how to apply a Disciplined Diversification(SM) strategy to your portfolio using
the principles of ADR, I would urge you to contact your own investment
professional. You may also want to refer to information on the subject on our
Web site, MFS.COM.

As always, we appreciate your confidence in MFS, and you can be sure of our
continued commitment to do the best we can to help you pursue your long-term
financial goals.

    Respectfully,

MANAGEMENT REVIEW
- -------------------------------------------------------------------------------

SUMMARY OF RESULTS

For the six months ended February 28, 2005, Class A shares of the MFS Municipal
Bond Fund provided a total return of 2.20%, not including sales charges. In
comparison, the fund's benchmark, the Lehman Brothers Municipal Bond Index,
returned 2.40%. The fund's investment objective is to provide as high a level
of current income exempt from federal income taxes as is considered consistent
with prudent investing while seeking protection of shareholders' capital. The
fund invests, under normal market conditions, at least 80% of its net assets in
securities and other investments, the interest on which is exempt from federal
income tax. The fund may invest in municipal securities, which are bonds or
other debt obligations of a U.S. state or political subdivision, such as a
county, city, town, village or authority.

MARKET ENVIRONMENT

At the start of the period, we believed that markets were concerned about the
sustainability of the economic recovery. Fixed income markets had finished
strongly in 2003. This bond-friendly environment was interrupted by strong U.S.
employment and economic data in the second quarter of 2004, which we believe
precipitated a bond market selloff. Accelerating domestic demand in the first
half of the period, coupled with rising inflation and a very accommodative
monetary stance caused the U.S. Federal Reserve to begin raising short-term
rates in June. Despite four more rate hikes in the second half of the year, we
believe U.S. economic conditions contributed to a decline in longer maturity
bond yields, while corporate and emerging bond yields narrowed to U.S.
Treasuries. Under this scenario the yield curve flattened - interest rates on
the short end of the curve moved up while rates on the long end decreased
slightly.

Compared to 2003, where we believed a large number of states and municipalities
issued debt in order to take advantage of historically low interest rates, the
rate of new bond issuance fell in 2004. However, demand for municipal bonds did
not decline with issuance. In our view, this supply- demand scenario aided
municipal bond performance over the period.

DETRACTORS FROM PERFORMANCE

Security selection in the credit enhanced (insured bonds) sector detracted from
performance. Our underweighted position, relative to the Lehman Brothers
Municipal Bond Index, in the tobacco sector modestly held back results for the
period. Our overweighting in pre-refunded bonds also hurt performance.

CONTRIBUTORS TO PERFORMANCE

The fund benefited from sector selection and our positioning on the yield
curve. Our overweighted position in the health care sector boosted relative
returns. Our relative underweighting in general obligation bonds also helped
results during the period.

PERFORMANCE SUMMARY THROUGH 2/28/05
- -------------------------------------------------------------------------------

Because mutual funds are designed for investors with long-term goals, we have
provided cumulative results as well as the average annual total returns for the
applicable time periods. Performance results reflect the percentage change in
net asset value, including the reinvestment of any dividends and capital gains
distributions. (See Notes to Performance Summary.)

INDEX DEFINITION

Lehman Brothers Municipal Bond Index - is a rules-based, market-value-weighted
index representative of the tax-exempt bond market.

It is not possible to invest directly in an index.

NOTES TO PERFORMANCE SUMMARY

Class A results including sales charge reflect the deduction of the maximum
4.75% sales charge. Class B results including sales charge reflect the
deduction of the applicable contingent deferred sales charge (CDSC), which
declines over six years from 4% to 0%.

Performance results reflect any applicable expense subsidies and waivers in
effect during the periods shown. Without such subsidies and waivers the fund's
performance results would be less favorable. Please see the prospectus and
financial statements for complete details.

From time to time the fund may receive proceeds from litigation settlements,
without which performance would be lower.

KEY RISK CONSIDERATIONS

A 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.

The portfolio invests in municipal bonds that are general obligations backed by
the full faith and credit of the municipal issuer. The portfolio may also
invest in municipal bonds called revenue obligations which are subject to a
higher degree of credit risk than general obligations. The prices of these
securities will decline when interest rates rise, and increase when rates fall.
In addition, municipal securities are subject to credit (failure to make timely
principal or interest payments) and maturity (longer maturity dates increase
security price fluctuations) risks.

The fixed income securities purchased by the portfolio may be traded in the
over-the-counter market rather than on an organized exchange and are subject to
liquidity risk. This means that they may be harder to purchase or sell at a
fair price. The inability to purchase or sell these fixed income securities at
a fair price could have a negative impact on the portfolio's performance.

Speculative bonds are subject to a higher risk that the issuer will default on
payments of principal and interest than higher-rated investment grade bonds.
Although the issuer's ability to make interest and principal payments appears
adequate, an adverse change in economic conditions or other circumstances is
more likely to cause a default by the issuer of a speculative bond than the
issuer of a higher-rated investment grade bond. If a security purchased by the
fund is downgraded to below investment grade, the security will be sold only if
MFS believes it is advantageous to do so.

The portfolio's investment in municipal securities may include municipal lease
obligations. Municipal lease obligations are undivided interests issued by a
state or municipality in a lease or installment purchase which generally
relates to equipment or facilities. When a portfolio invests in municipal lease
obligations, it may have limited recourse in the event of default or
termination. In some cases, payments under municipal leases do not have to be
made unless the appropriate legislative body specifically approves money for
that purpose.

Please see the prospectus for further information regarding these and other
risk considerations.

EXPENSE TABLE
- -------------------------------------------------------------------------------

FUND EXPENSES BORNE BY SHAREHOLDERS DURING THE PERIOD FROM
SEPTEMBER 1, 2004, THROUGH FEBRUARY 28, 2005.

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, September 1, 2004 through February
28, 2005.

ACTUAL EXPENSES

The first line for each share class in the table on the next page 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 table on the next page 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.

** Expenses paid is equal to each class' annualized expense ratio for the most
   recent six month period, 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.

NOTES TO FINANCIAL STATEMENTS (unaudited)
- -------------------------------------------------------------------------------

(1) BUSINESS AND ORGANIZATION

MFS Municipal Bond Fund (the fund) is a diversified series of MFS Series Trust
IV (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, interest from the security could become taxable and the security
could decline in value.

INVESTMENT VALUATIONS - Bonds and other fixed income securities (other than
short-term obligations) in the fund's portfolio are valued at an evaluated bid
price as reported by an independent pricing service, or to the extent a
valuation is not reported by a pricing service, such securities are valued on
the basis of quotes from brokers and dealers. Prices obtained from pricing
services utilize both dealer-supplied valuations and electronic data processing
techniques which take into account appropriate 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 quoted prices or exchange or over-the-
counter prices, since such valuations are believed to reflect more accurately
the fair value of such securities. Short-term obligations with a remaining
maturity in excess of 60 days will be valued upon dealer-supplied valuations.
All other short-term obligations in the fund's portfolio are valued at
amortized cost, which approximates market value as determined by the Board of
Trustees. When pricing service information or market quotations are not readily
available, securities are priced at fair value as determined under the
direction of the Board of Trustees.

SWAP AGREEMENTS - The fund may enter into swap agreements. A swap is an
exchange of cash payments between the fund and another party, which is based on
a specific financial index. Cash payments are exchanged at specified intervals
and the expected income or expense is recorded on the accrual basis. The value
of the swap is adjusted daily and the change in value is recorded as unrealized
appreciation or depreciation. Risks may arise upon entering into these
agreements from the potential inability of counterparties to meet the terms of
their contract and from unanticipated changes in the value of the financial
index on which the swap agreement is based. The fund uses swaps for both
hedging and non-hedging purposes. For hedging purposes, the fund may use swaps
to reduce its exposure to interest and foreign exchange rate fluctuations. For
non-hedging purposes, the fund may use swaps to take a position on anticipated
changes in the underlying financial index.

INTEREST RATE SWAP AGREEMENTS - Interest rate swap agreements are agreements to
exchange cash flows periodically based on a notional principal amount, for
example the exchange of fixed rate interest payments for floating rate interest
payments which are based on a specific financial index, or the exchange of two
distinct floating rate payments. The net receivable or payable associated with
these payments is accrued daily and is recorded as net interest income or
expense. For financial statement purposes, the net interest income or expense
periodically recognized for an interest rate swap is recorded in the same line
item as any unrealized and realized gains or losses recognized for that
instrument. The primary risk associated with interest rate swap agreements is
that unfavorable changes in the fluctuation of interest rates could adversely
impact the fund.

SHORT TERM FEES - For purchases made on or after July 1, 2004 and before April
1, 2005, the fund will charge a 2% redemption fee (which is retained by the
fund) on proceeds from Class A and Class B shares redeemed or exchanged within
5 business days following their acquisition (either by purchase or exchange).
Effective April 1, 2005, the fund will no longer charge a redemption fee. See
the fund's prospectus for details. Any redemption fees charged are accounted
for as an addition to paid-in capital.

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 February 28, 2005 is shown as a
reduction of total 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 tax-
exempt and taxable 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 the
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 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. Common
types of book and tax differences that could occur include differences in
accounting for derivatives, capital losses, and amortization and accretion on
debt securities.

The tax character of distributions declared for the years ended August 31, 2004
and August 31, 2003 was as follows:

                                                        8/31/04         8/31/03

Distributions declared from tax-exempt income:      $63,189,015     $67,795,702
- -------------------------------------------------------------------------------

As of August 31, 2004, the components of distributable earnings (accumulated
losses) on a tax basis were as follows:

          Undistributed tax-exempt income                 $4,409,827
          ----------------------------------------------------------
          Capital loss carryforward                         (761,962)
          ----------------------------------------------------------
          Unrealized appreciation (depreciation)         116,069,197
          ----------------------------------------------------------
          Other temporary differences                     (5,011,617)
          ----------------------------------------------------------

For federal income tax purposes, the capital loss carryforward may be applied
against any net taxable realized gains of each succeeding year until the
earlier of its utilization or expiration on August 31, 2009, $(349,381) and
August 31, 2011, $(412,581).

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 the following annual
rates:

          First $1.3 billion of average net assets              0.40%
          ----------------------------------------------------------
          Average net assets in excess of $1.3 billion          0.37%
          ----------------------------------------------------------
          Average net assets in excess of $2.0 billion          0.35%
          ----------------------------------------------------------

As part of a settlement agreement with the New York Attorney General concerning
market timing and related matters (See Legal Proceedings footnote), MFS has
agreed to reduce the fund's management fee to 0.30% of average daily net assets
for the period March 1, 2004 through February 28, 2009, which is shown as a
reduction of total expenses in the Statement of Operations. During this time
period, the Board of Trustees will continue to review the appropriateness of
all advisory fees in accordance with their oversight responsibilities. After
February 28, 2009 the management fee will be determined in accordance with then
existing review policies approved by the Board of Trustees overseeing the fund.
Management fees incurred for the six months ended February 28, 2005 were an
effective rate of 0.30% of average daily net assets on an annualized basis.

The fund pays compensation to its Independent Trustees in the form of a
retainer, attendance fees, and additional compensation to Board and Committee
chairpersons, and pays no compensation directly to its Trustees who are
officers of the investment adviser, or to officers of the fund, 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, MFS Fund
Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). The fund has an
unfunded defined benefit plan for retired Independent Trustees. Included in
Trustees' compensation is a pension expense of $3,131 for retired Independent
Trustees for the six months ended February 28, 2005.

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. MFS has agreed to
reimburse each of the funds for a proportional share of substantially all of
the payments made by the funds to Tarantino LLC and also to provide office
space and other administrative support and supplies to the ICCO. The funds can
terminate the Agreement with Tarantino LLC at any time under the terms of the
Agreement.

ADMINISTRATOR - MFS provides certain financial, legal, shareholder
communications, compliance, and other administrative services to certain funds
for which MFS acts as investment adviser. Under an administrative services
agreement between the funds and MFS, MFS is entitled to partial reimbursement
of the costs MFS incurs to provide these services, subject to review and
approval by the Board of Trustees. Each fund is allocated a portion of these
administrative costs based on its size and relative average net assets. The
fund paid MFS an administrative fee up to the following annual percentage rates
of the fund's average daily net assets:

The March 1, 2005 rates were not effective during the current reporting period.
For the six months ended February 28, 2005, the fund paid MFS $32,752,
equivalent to 0.00549% of average daily net assets, to partially reimburse MFS
for the costs of providing administrative services.

DISTRIBUTOR - MFD, a wholly owned subsidiary of MFS, as distributor, received
$48,789 for the six months ended February 28, 2005, 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 B 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 an annual
percentage of its average daily net assets attributable to certain share
classes as compensation for services provided by MFD and financial
intermediaries in connection with the distribution and servicing of its shares.
One component of the plan is a distribution fee and another is a service fee
paid by MFD to financial intermediaries that enter into sales or service
agreements with MFD or its affiliates based on the average daily net assets of
accounts attributable to such intermediaries. The fees are calculated based on
each class' average daily net assets. The maximum distribution and service fees
for each class of shares are as follows:

                                                             CLASS B

          Distribution Fee                                      0.75%
          ----------------------------------------------------------
          Service Fee                                           0.25%
          ----------------------------------------------------------
          Total Distribution Plan                               1.00%
          ----------------------------------------------------------

Except in the case of the 0.25% per annum Class B service fee paid by the fund
upon the sale of Class B shares in the first year, payment of the Class B
service fee will not be implemented until such date as the Trustees of the
trust may determine.

MFD may retain all or a portion of the service fee, including for accounts for
which there is no financial intermediary of record. MFD received no portion of
the Class B service fee for the six months ended February 28, 2005.

Fees incurred under the distribution plan during the six months ended February
28, 2005 were as follows:

                                                             CLASS B

          Effective Annual Percentage Rates                     0.76%
          ----------------------------------------------------------

Certain Class A shares are subject to a contingent deferred sales charge in the
event of a shareholder redemption within, for Class A shares, 12 months
following the 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 six months
ended February 28, 2005 were as follows:

                                                CLASS A     CLASS B

         Contingent Deferred Sales Charges
         Imposed                                $2,888     $63,965
         -----------------------------------------------------------

SHAREHOLDER SERVICING AGENT - Included in shareholder servicing costs is a fee
paid to MFSC, a wholly owned subsidiary of MFS, for its services as shareholder
servicing agent. The fee, which is calculated as a percentage of the fund's
average daily net assets is set periodically under the supervision of the
fund's Trustees. For the period September 1, 2004 through December 31, 2004,
the fund was charged up to 0.0861% of its average daily net assets. For the
period January 1, 2005 through February 28, 2005, the fund is charged up to
0.1035% of its average daily net assets. For the six months ended February 28,
2005, the fund paid MFSC a fee of $537,058 for shareholder services which
equated to 0.0901% of the fund's average daily net assets. Effective March 1,
2005, the fund is charged up to 0.1159% of its average daily net assets.
Shareholder service costs include out of pocket expenses and sub accounting
services expenses paid by MFSC on behalf of the fund and subsequently
reimbursed to MFSC which amounted to $116,224, and other costs paid by the fund
directly to unaffiliated vendors for the six months ended February 28, 2005.

(6) LINE OF CREDIT

The fund and other affiliated funds participate in an $800 million unsecured
line of credit provided by a syndication of banks under a line of credit
agreement. Borrowings may be made for temporary financing needs. Interest is
charged to each fund, based on its borrowings, at a rate equal to the Federal
Reserve funds rate plus 0.50%. 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 calendar quarter. The commitment fee
allocated to the fund for the six months ended February 28, 2005 was $137, and
is included in miscellaneous expense. The fund had no significant borrowings
during the six months ended February 28, 2005.

(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 and foreign currency exchange rates. These financial
instruments include swap agreements. 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.

to legal or contractual restrictions on resale, excluding securities issued
under Rule 144A, constituting 6.99% of net assets which may not be publicly
sold without registration under the Securities Act of 1933. The fund does not
have the right to demand that such securities be registered. The value of these
securities is determined by valuations furnished by dealers or by a pricing
service, or if not available, in good faith at the direction of the Trustees.

(9) CONCENTRATION OF CREDIT RISK

At February 28, 2005, 56.98% 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 19.85% of total investments.

(10) LEGAL PROCEEDINGS

On March 31, 2004, MFS settled an administrative proceeding with the Securities
and Exchange Commission ("SEC") regarding disclosure of brokerage allocation
practices in connection with MFS fund sales (the term "MFS funds" means the
open-end registered management investment companies sponsored by MFS). Under
the terms of the settlement, in which MFS neither admitted nor denied any
wrongdoing, MFS agreed to pay (one dollar) $1.00 in disgorgement and $50
million in penalty to certain MFS funds, pursuant to a plan developed by an
independent distribution consultant. The brokerage allocation practices which
were the subject of this proceeding were discontinued by MFS in November 2003.
The agreement with the SEC is reflected in an order of the SEC. The SEC
settlement order states that MFS failed to adequately disclose to the Boards of
Trustees and to shareholders of the MFS funds the specifics of its preferred
arrangements with certain brokerage firms selling MFS fund shares. The SEC
settlement order states that MFS had in place policies designed to obtain best
execution of all MFS fund trades. As part of the settlement, MFS retained an
independent compliance consultant to review the completeness of its current
policies and practices regarding disclosure to MFS fund trustees and to MFS
fund shareholders of strategic alliances between MFS or its affiliates and
broker-dealers and other financial intermediaries who support the sale of MFS
fund shares. Pursuant to the SEC order, on July 28, 2004, MFS transferred these
settlement amounts to the SEC, and those MFS funds entitled to these settlement
amounts accrued an estimate of their pro rata portion of these amounts. The
final distribution plan was approved by the SEC on January 21, 2005 and the
affected MFS funds received the payment on February 16, 2005.

In addition, in February, 2004, MFS reached agreement with the SEC, the New
York Attorney General ("NYAG") and the Bureau of Securities Regulation of the
State of New Hampshire ("NH") to settle administrative proceedings alleging
false and misleading information in certain MFS open-end retail fund ("MFS
retail funds") prospectuses regarding market timing and related matters (the
"February Settlements"). These regulators alleged that prospectus language for
certain MFS retail funds was false and misleading because, although the
prospectuses for those funds in the regulators' view indicated that they
prohibited market timing, MFS did not limit trading activity in 11 domestic
large cap stock, high grade bond and money market retail funds. MFS' former
Chief Executive Officer and former President also reached agreement with the
SEC in which they agreed to, among other terms, monetary fines and temporary
suspensions from association with any investment adviser or registered
investment company. These individuals have resigned their positions with, and
will not be returning to, MFS and the MFS funds. Under the terms of the
February Settlements, MFS and the executives neither admit nor deny wrongdoing.

Under the terms of the February Settlements, a $225 million pool has been
established for distribution to shareholders in certain MFS retail funds, which
has been funded by MFS and of which $50 million is characterized as a penalty.
This pool will be distributed in accordance with a methodology developed by an
independent distribution consultant in consultation with MFS and the Board of
Trustees of the MFS retail funds, and acceptable to the SEC. MFS has further
agreed with NYAG to reduce its management fees in the aggregate amount of
approximately $25 million annually over the next five years, and not to
increase certain management fees during this period. MFS has also paid an
administrative fine to NH in the amount of $1 million, which will be used for
investor education purposes (NH retained $250,000 and $750,000 was contributed
to the North American Securities Administrators Association's Investor
Protection Trust). In addition, under the terms of the February Settlements,
MFS is in the process of adopting certain governance changes and reviewing its
policies and procedures.

Since December 2003, MFS, MFS Fund Distributors, Inc., MFS Service Center,
Inc., MFS Corporation Retirement Committee, Sun Life Financial Inc., various
MFS funds, certain current and/or former Trustees of these MFS funds, and
certain officers of MFS have been named as defendants in multiple lawsuits
filed in federal and state courts. The lawsuits variously have been commenced
as class actions or individual actions on behalf of investors who purchased,
held or redeemed shares of the MFS funds during specified periods, as ERISA
actions by participants in certain retirement plan accounts on behalf of those
accounts, or as derivative actions on behalf of the MFS funds. The lawsuits
relating to market timing and related matters have been transferred to, and
consolidated before, the United States District Court for the District of
Maryland, as part of a multi-district litigation of market timing and related
claims involving several other fund complexes (In re Mutual Funds Investment
Litigation (Alger, Columbia, Janus, MFS, One Group, Putnam, Allianz Dresdner),
No. 1:04-md-15863 (transfer began March 19, 2004)). The market timing cases
related to the MFS complex are Riggs v. MFS et al., Case No. 04-cv-01162-JFM
(direct), Hammerslough v. MFS et al., Case No. 04-md-01620 (derivative) and
Anita Walker v. MFS et al., Case No. 1:04-CV-01758 (ERISA). The plaintiffs in
these consolidated lawsuits generally seek injunctive relief including removal
of the named Trustees, adviser and distributor, rescission of contracts and
12b-1 Plans, disgorgement of fees and profits, monetary damages, punitive
damages, attorney's fees and costs and other equitable and declaratory relief.
Two lawsuits alleging improper brokerage allocation practices and excessive
compensation are pending in the United States District Court for the District
of Massachusetts (Forsythe v. Sun Life Financial Inc., et al., No. 04cv10584
(GAO) (a consolidated action) and Marcus Dumond, et al. v. Massachusetts
Financial Servs. Co., et al., No. 04cv11458 (GAO)). The plaintiffs in these
lawsuits generally seek compensatory damages, punitive damages, recovery of
fees, rescission of contracts, an accounting, restitution, declaratory relief,
equitable and/or injunctive relief and attorney's fees and costs. The various
lawsuits generally allege that some or all of the defendants (i) permitted or
acquiesced in market timing and/or late trading in some of the MFS funds,
inadequately disclosed MFS' internal policies concerning market timing and such
matters (ii) received excessive compensation as fiduciaries to the MFS funds,
or (iii) permitted or acquiesced in the improper use of fund assets by MFS to
support the distribution of MFS fund shares and inadequately disclosed MFS' use
of fund assets in this manner. The actions assert that some or all of the
defendants violated the federal securities laws, including the Securities Act
of 1933 and the Securities Exchange Act of 1934, the Investment Company Act of
1940 and the Investment Advisers Act of 1940, the Employee Retirement Income
Security Act of 1974, as well as fiduciary duties and other violations of
common law. Insofar as any of the actions is appropriately brought derivatively
on behalf of any of the MFS funds, any recovery will inure to the benefit of
the MFS funds. The defendants are reviewing the allegations of the multiple
complaints and will respond appropriately. Additional lawsuits based on similar
allegations may be filed in the future.

Any potential resolution of these matters may include, but not be limited to,
judgments or settlements for damages against MFS, the MFS funds, or any other
named defendant. As noted above, as part of the regulatory settlements, MFS has
established a restitution pool in the amount of $225 million to compensate
certain shareholders of certain MFS retail funds for damages that they
allegedly sustained as a result of market timing or late trading in certain of
the MFS retail funds, and distributed $50 million to affected MFS funds to
compensate those funds based upon the amount of brokerage commissions allocated
in recognition of MFS fund sales. It is not clear whether these amounts will be
sufficient to compensate shareholders for all of the damage they allegedly
sustained, whether certain shareholders or putative class members may have
additional claims to compensation, or whether the damages that may be awarded
in any of the actions will exceed these amounts. In the event the MFS funds
incur any losses, costs or expenses in connection with such lawsuits, the
Boards of Trustees of the affected MFS funds may pursue claims on behalf of
such funds against any party that may have liability to the funds in respect
thereof.

Review of these matters by the independent Trustees of the MFS funds and their
counsel is continuing. There can be no assurance that these regulatory actions
and lawsuits, or the adverse publicity associated with these developments, will
not result in increased fund redemptions, reduced sales of fund shares, or
other adverse consequences to the MFS funds.
