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

Dear Shareholders,

[Photo of Robert J. Manning]

As the firm's new Chief Executive Officer, I want to thank you for your
continued trust in MFS and tell you about the series of actions we have taken
since our recent settlements with the regulators. These actions are designed to
enhance the governance structure of the MFS funds, tighten our business
practices, and strengthen the management team at MFS.

In early February, Robert Pozen joined MFS as non-executive Chairman. A seasoned
veteran of the mutual fund industry, Bob has held prior positions as President
of Fidelity Management & Research Company, as Associate General Counsel of the
Securities and Exchange Commission, and as a visiting professor at Harvard Law
School.

In an effort to develop and implement policies that we believe will set a new
standard in regulatory compliance, MFS has hired two new senior executives.
Jeffrey Carp is joining us as General Counsel with responsibility for all of our
legal affairs. Previously he was a senior partner with the law firm of Hale and
Dorr LLP. Also joining MFS in the new position of Executive Vice President of
Regulatory Affairs is Maria Dwyer, who returned to the firm after serving as a
senior executive at Fidelity. At MFS, Maria is in charge of compliance, internal
audit, and fund treasury.

In the area of governance, we have taken steps to enhance the independence of
our funds' boards of trustees to better protect the interests of shareholders.
We have independent board chairs and at least 75% of the trustees are
independent. The trustees will appoint not only their own counsel but also an
independent compliance officer. This officer will assist the boards and their
committees in monitoring the MFS funds' compliance with federal and state
regulations.

In February, MFS reached agreements with federal and state regulators to settle
their administrative proceedings against the firm and two senior executives in
connection with market timing and related issues. Under the terms of the
settlements, we agreed to pay $225 million to compensate affected retail fund
shareholders. The $225 million will be distributed in accordance with a
distribution plan developed by an independent consultant.

We have further agreed with state regulators to reduce management fees on
certain funds we advise by approximately $25 million annually over the next five
years and to pay an administrative fine of $1 million, which will be used for
the purpose of investor education. We have introduced a set of policies designed
to protect the MFS funds and MFS fund shareholders from market timing abuses. By
July, all MFS retail funds, except money market funds, will have a 2% redemption
fee on short-term trades. Our global, international, high-yield, mid- and
small-cap funds will impose the 2% fee on redemptions or exchanges of fund
shares made within 30 calendar days of a share purchase. For all other MFS
funds, except money market funds, the 2% fee will be imposed on redemptions or
exchanges made within 5 business days of a share purchase. See the fund
prospectus for more information.

We continue to use fair value pricing, a strategy that minimizes the potential
for investors to take advantage of "stale" prices. These can occur, as one
example, when funds own foreign securities whose prices close on overseas
exchanges in different time zones. At the same time, we enhanced our monitoring
of excessive trading. We did so by increasing our staff and updating our
computer systems to improve our ability to detect excessive trading in our
funds. Finally, we are supporting industry efforts to establish a "hard" 4 p.m.
close on all trading, which would prevent the possibility of late trading.

In March, MFS reached a second settlement with the SEC under an administrative
proceeding resolving the SEC's investigation into how we disclosed brokerage
allocation practices in connection with fund sales. According to the settlement
order, we did not effectively disclose the potential conflict of interest that
may arise from these arrangements.

Under the terms of the settlement, MFS has agreed to pay one dollar in
disgorgement and $50 million in penalty to MFS fund shareholders. The settlement
noted that MFS had policies in place designed to obtain best execution of all
trades of securities within MFS portfolios.

This past November, MFS eliminated the above mentioned practice of directing
brokerage commissions to certain firms in recognition of fund sales.
Additionally, we announced in March that we would ban the use of soft dollars to
acquire third-party securities research and market data. Soft dollars are
permitted under federal securities laws. In fact, it is a common industry
practice to use a portion of the brokerage commissions to pay for certain
research and execution products and services that are provided to asset
managers. MFS will now pay cash out of its own pocket for third-party research
and market data.

MFS continues to be financially strong, with more than U.S. $140 billion (as of
12/31/03) in assets under management, which continued to be stable during the
first quarter of 2004. We also have the full support of our parent company, Sun
Life Financial, an internationally diversified financial services firm that
manages more than U.S. $269 billion (as of 12/31/03).

We chose to settle these two proceedings with the SEC so we could concentrate on
serving our fund shareholders. As Chief Investment Officer, my focus is on
ensuring that our portfolio teams work closely together and take full advantage
of all the resources available to them to deliver the best possible investment
performance.

As the inventor of the open-end mutual fund in America in 1924, MFS has a strong
tradition and culture of innovation. By strengthening our business and
governance practices, we believe we have an unprecedented opportunity to set a
new standard in the mutual fund industry.

As I look ahead, I do so with confidence. The collaboration among MFS employees,
many of whom have worked at the firm for their entire careers, continues as we
remain singularly dedicated to our clients. It has been our sincere privilege to
serve you, and we thank you for the confidence that you have shown in MFS.

    Respectfully,

/s/ Robert J. Manning

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

MARKET ENVIRONMENT

The U.S. government bond market for the 12 months ended February 29, 2004 was
influenced by the Federal Reserve Board's (the Fed) desire to foster economic
growth and by low interest rates paid by U.S. government bonds. Although
interest rates at the end of February 2004 were not that different from what
they had been a year earlier, they were fairly volatile during the 12-month
period, especially in the summer months of 2003 following the Fed's 25 basis
point (0.25%) cut in short-term interest rates. For example, the yield of the
10-year U.S. Treasury bond reached 3.10% in June -- a four-decade low. However
Treasury interest rates then rose again from late June through August and
reached 4.60% in September 2003. By February 29, 2004, however, the 10-year
Treasury bond yield had fallen back to 3.97%.

FUND POSITIONING

The two most significant shifts in fund positioning were to cut the fund's
allocation to U.S. Treasury securities and to increase holdings in U.S.
government agency securities. On February 28, 2003, the fund held more than 34%
of its assets in U.S. Treasuries and roughly 15% in U.S. government agency
bonds. By the end of the reporting period in February 2004, U.S. Treasuries
represented only about 12% of fund assets and U.S. government agencies more than
40%. The cuts in the fund's U.S. Treasury holdings began in the middle of 2003.

The fund's position in government agencies was built throughout the period
because we became more comfortable with the credit quality of these issuers as a
result of increased regulatory and market scrutiny. In addition, we believe
those securities offered more attractive yields than comparable maturity
Treasury issues. (The principal value and interest on Treasury securities are
guaranteed by the U.S. government if held to maturity.)

DETRACTORS FROM PERFORMANCE

Fund returns lagged the fund's benchmark, the Lehman Brothers Government
Mortgage Index, because of the fund's relative underweighting in mortgage-
backed securities over the last quarter of 2003. Mortgage rates were fairly
stable, homeowner refinancing decreased, and new home purchases were down from
levels earlier in the year. As a result, mortgage-backed securities appreciated
in value, but the fund did not participate fully in that upward move because of
its underweighting in the group.

CONTRIBUTORS TO PERFORMANCE

The fund's U.S. government agency positions were the most noteworthy
contributors to fund performance. Because of the upheaval in U.S. Treasury
interest rates in the summer of 2003, we believe that fixed-income investors
became more risk averse during those summer months. As a result, the difference
in yields (spreads) increased between guaranteed U.S. Treasury securities and
U.S. government agencies that carry greater credit risk. However, in August,
those spreads began to narrow. In our view, investors became more comfortable
with the attendant risks and higher yields offered by agency securities. As
spreads decreased, yields on government agency securities came down, and their
prices appreciated. Because we had increased our agency positions, the fund
participated in that appreciation.

INDEX DEFINITION

LEHMAN BROTHERS GOVERNMENT/MORTGAGE INDEX - measures the performance of the
government and mortgage securities markets.

It is not possible to invest directly in an index.

NOTES TO PERFORMANCE SUMMARY

Class A and 529A results, including sales charge, reflects the deduction of the
maximum 4.75% sales charge. Class B and 529B results, including sales charge,
reflects 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, redeemed within one year from the end of the calendar
month of purchase reflects 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, and 529C shares are only available in conjunction with
qualified tuition programs, such as the MFS 529 Savings Plan.

Performance for share classes offered after class A shares includes the
performance of the fund's class A shares for periods prior to their offering.
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 initial share class, and lower performance
for share classes with lower operating expenses than the initial share class.

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

KEY RISK CONSIDERATIONS

Government guarantees apply to the underlying securities only and not to the
prices and yields of the portfolio.

The portfolio may invest in mortgage-backed securities, which during times of
fluctuating interest rates, may increase or decrease more than other fixed-
income securities.

These risks may increase share price volatility. Please see the prospectus for
further information regarding these and other risk considerations.

This report is prepared for the general information of shareholders. It is
authorized for distribution to prospective investors only when preceded or
accompanied by a current prospectus.

FINANCIAL STATEMENTS        FINANCIAL HIGHLIGHTS
- ------------------------------------------------------------------------------------------------------------------------------

The financial highlights table is intended to help you understand the fund's financial performance for the past 5 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. This information has been audited by the fund's
independent auditors, whose report, together with the fund's financial statements, are included in this report.

       February 28, 2002 was to decrease net investment income per share by $0.04, increase net realized and unrealized gains
       and losses per share by $0.04, and decrease the ratio of net investment income to average net assets by 0.45%. Per

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

(1) BUSINESS AND ORGANIZATION

MFS Government Securities Fund (the fund) is organized as a Massachusetts
business trust and is registered under the Investment Company Act of 1940, as
amended, as a diversified open-end management investment company.

(2) SIGNIFICANT ACCOUNTING POLICIES

GENERAL - The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America 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 - The fund uses independent pricing services approved by
the Board of Trustees wherever possible to value its portfolio securities.
Portfolio securities are valued at current market prices where current market
prices are readily available, or the fund may fair value portfolio securities
under the direction of the Board of Trustees when a determination is made that
current market prices are not readily available. 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. Bonds and other fixed income
securities for which it is determined that current market prices are not readily
available will be fair valued under the direction of the Board of Trustees.
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 constitutes market value as
determined by the Board of Trustees.

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.

SECURITY LOANS - State Street Bank and Trust Company ("State Street"), as
lending agent, 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
provides 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 agent. On loans collateralized by U.S. Treasury
securities, a fee is received from the Borrower, and is allocated between the
fund and the lending agent. Income from securities lending is included in
interest income on the Statement of Operations. The dividend and interest income
earned on the securities loaned is accounted for in the same manner as other
dividend and interest income.

At February 29, 2004 there were no securities on loan.

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 accounting principles generally accepted in the United Sates of America.
All discount is accreted for tax reporting purposes as required by federal
income tax regulations. Some securities may be purchased on a "when- issued" or
"forward delivery" basis, which means that the securities will be delivered to
the fund at a future date, usually beyond customary settlement time.

The fund may enter in TBA (to be announced) purchase commitments to purchase
securities for a fixed unit price at a future date. Although the unit price has
been established, the principal value has not been finalized. However, the
principal amount of the commitments will not fluctuate more than 0.01%. The fund
holds, and maintains until settlement date, cash or high-grade debt obligations
in an amount sufficient to meet the purchase price, or the fund may enter into
offsetting contracts for the forward sale of other securities it owns. Income on
the securities will not be earned until settlement date. TBA purchase
commitments may be considered securities in themselves, and involve a risk of
loss if the value of the security to be purchased declines prior to settlement
date, which is in addition to the risk of decline in the value of the fund's
other assets. Unsettled TBA purchase commitments are valued at the current
market value of the underlying securities, according to the procedures described
under "Investment Valuations" above.

The fund may enter into TBA sale commitments to hedge its portfolio positions or
to sell mortgage-backed securities it owns under delayed delivery arrangements.
Proceeds of TBA sale commitments are not received until the contractual
settlement date. During the time a TBA sale commitment is outstanding,
equivalent deliverable securities, or an offsetting TBA purchase commitment
deliverable on or before the sale commitment date, are held as "cover" for the
transaction.

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 year ended February 29, 2004, 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 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 mortgage-backed securities and amortization and accretion on debt
securities.

The tax character of distributions declared for the years ended February 28,
2003 and February 29, 2004 was as follows:

                                                  2/29/04            2/28/03

Distributions declared from:
- ------------------------------------------------------------------------------
  Ordinary income                             $55,327,053        $59,381,578
- ------------------------------------------------------------------------------

During the year ended February 29, 2004, accumulated distributions in excess of
net investment income decreased by $16,496,716 and accumulated net realized loss
on investments increased by $16,496,716 due to differences between book and tax
accounting for mortgage-backed securities and amortization and accretion on debt
securities. This change had no effect on the net assets or net asset value per
share.

As of February 29, 2004, the components of distributable earnings (accumulated
losses) on a tax basis were as follows:

Undistributed ordinary income                                        $495,386
- ------------------------------------------------------------------------------
Capital loss carryforward                                         (33,576,113)
- ------------------------------------------------------------------------------
Post-October capital loss deferral                                 (6,095,300)
- ------------------------------------------------------------------------------
Unrealized appreciation                                            21,383,815
- ------------------------------------------------------------------------------
Other temporary differences                                        (3,299,064)
- ------------------------------------------------------------------------------

Post-October capital loss deferrals represent losses realized during the current
fiscal year, but recognized for tax purposes in the next fiscal year.

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

MULTIPLE CLASSES OF SHARES OF BENEFICIAL INTEREST - The fund offers multiple
classes of shares, which differ in their respective distribution and service
fees. All shareholders bear the common expenses of the fund based on the value
of settled shares outstanding of each class, without distinction between share
classes. Dividends are declared separately for each class. Differences in per
share dividend rates are generally due to differences in separate class
expenses. Class B and Class 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 0.40% of
the fund's average daily net assets. The investment adviser has contractually
agreed to waive a portion of its fee, which is shown as a reduction of total
expenses in the Statement of Operations. Management fees incurred for the year
ended February 29, 2004 were 0.35% of average daily net assets on an annualized
basis.

As part of the settlement agreement with the New York Attorney General
concerning market timing and related matters, 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. 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.

The fund pays compensation to the Independent Trustees ("Trustees") in the form
of both a retainer and attendance fees, 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 Trustees and an unfunded retirement
benefit deferral plan for current Trustees. Included in Trustees' compensation
is a net increase of $1,367 as a result of the change in the fund's pension
liability for current Trustees and a pension expense of $7,843 for retired
Trustees for the year ended February 29, 2004.

ADMINISTRATOR - The fund has an administrative services agreement with MFS to
provide the fund with certain financial, legal, shareholder communications,
compliance, and other administrative services. As a partial reimbursement for
the cost of providing these services, the fund pays MFS an administrative fee up
to the following annual percentage rates of the fund's average daily net assets:

          First $2 billion                                   0.0175%
          ----------------------------------------------------------
          Next $2.5 billion                                  0.0130%
          ----------------------------------------------------------
          Next $2.5 billion                                  0.0005%
          ----------------------------------------------------------
          In excess of $7 billion                            0.0000%
          ----------------------------------------------------------

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
$137,926 and $1,187 for the year ended February 29, 2004 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
in order that MFD may pay expenses on behalf of the fund related to the
distribution and servicing of its shares. These expenses include a service fee
paid to each securities dealer that enters into a sales agreement with MFD based
on the average daily net assets of accounts attributable to such dealers. 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:

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
0.25% 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.

(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 bank's
base rate plus 50%. A commitment fee of $13,479 which is based on the average
daily unused portion of the line of credit is included in miscellaneous expense.
The fund had no significant borrowings during the year ended February 29, 2004.

(7) LEGAL PROCEEDINGS

On March 31, 2004, MFS settled an administrative proceeding regarding disclosure
of brokerage allocation practices in connection with fund sales. 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 to be approved by an independent
distribution consultant. The agreement with the SEC is reflected in an order of
the SEC. The 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
settlement order states that MFS had in place policies designed to obtain best
execution of all fund trades.

As part of the settlement, MFS also agreed to retain an independent compliance
consultant to review the completeness of its disclosure to fund trustees and to
fund shareholders of strategic alliances between MFS or its affiliates and
broker-dealers and other financial advisers who support the sale of fund shares.
The brokerage allocation practices which were the subject of this proceeding
were discontinued by MFS in November 2003.

In addition, in February, 2004, MFS reached agreement with the Securities and
Exchange Commission ("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 fund prospectuses regarding market timing and related matters (the
"February Settlements"). These regulators alleged that prospectus language for
certain MFS funds was false and misleading because, although the prospectuses
for those funds in the regulators' view indicated that the funds prohibited
market timing, MFS did not limit trading activity in 11 domestic large cap
stock, high grade bond and money market funds. MFS' former Chief Executive
Officer, John W. Ballen, and former President, Kevin R. Parke, have also
reached agreement with the SEC (Messrs. Ballen and Parke resigned their
director and officer positions with MFS on February 13, 2004). 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 of the MFS funds offered
to retail investors ("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 Boards of Trustees of the Retail
Funds, and acceptable to the SEC. MFS has further agreed with the 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 will
retain $250,000 and $750,000 will be contributed to the North American
Securities Administrators Association's Investor Protection Trust). In addition,
MFS and the Retail Funds will adopt certain governance changes.

Messrs. Ballen and Parke have agreed to temporary suspensions from association
with any registered investment company or investment adviser, will pay
approximately $315,000 each to the SEC, and resigned their positions as trustees
of all MFS funds, and Mr. Ballen resigned his position as President of all MFS
funds, effective February 6, 2004. Messrs. Ballen and Parke will not be
returning to MFS or the MFS funds after their suspensions.

Since December 2003, MFS, Sun Life Financial Inc., various MFS funds, the
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 funds during
specified periods, as class actions on behalf of participants in certain
retirement plan accounts, or as derivative actions on behalf of the MFS funds.
The 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, and received excessive compensation as fiduciaries to the MFS fund, or
(ii) permitted or acquiesced in the improper use of fund assets by MFS to
support the distribution of 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. The
lawsuits seek unspecified compensatory damages. 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 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 the Retail Funds for damages that they allegedly
sustained as a result of market timing or late trading in certain of the funds,
and will pay $50 million to compensate certain MFS funds based upon the amount
of brokerage commissions allocated in recognition of 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 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 funds.

INDEPENDENT AUDITORS' REPORT
- --------------------------------------------------------------------------------

To the Trustees and the Shareholders of MFS Government Securities Fund:

We have audited the accompanying statement of assets and liabilities of MFS
Government Securities Fund, including the portfolio of investments, as of
February 29, 2004, and the related statement of operations for the year then
ended, the statement of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the periods
presented. These financial statements and financial highlights are the
responsibility of the fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of February 29, 2004, by correspondence with the custodian.
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of MFS
Government Securities Fund at February 29, 2004, the results of its operations
for the year then ended, the changes in its net assets for each of the two years
in the period then ended, and the financial highlights for each of the periods
presented, in conformity with accounting principles generally accepted in the
United States of America.

ITEM 4(E)(1):

         reporting of the Registrant. In the event such services arise between
         regular meetings of the Audit Committee and it is not practical to seek
         pre-approval at the next regular meeting of the Audit Committee, such
         services may be referred to the Chair of the Audit Committee for
         approval; provided that, the Chair may not approve any individual
         engagement for such services exceeding $50,000 or multiple engagements
         for such services in the aggregate exceeding $100,000 between such
         regular meetings of the Audit Committee. Any engagement approved by the

         presented for ratification by the entire Audit Committee at its next
         regularly scheduled meeting.

ITEM 4(E)(2):
None, or 0%, of the services relating to the Audit-Related Fees, Tax Fees and
All Other Fees paid by the Registrant and MFS and MFS Related Entities disclosed
above were approved by the audit committee pursuant to paragraph (c)(7)(i)(C) of
Rule 2-01 of Regulation S-X (which permits audit committee approval after the
