LETTER FROM THE CHAIRMAN

Dear Shareholders,

Our firm was built on the philosophy that bottom- up fundamental research is the
best means of achieving superior long term investment performance. When you're
managing billions of dollars for investors, we think you have an obligation to
have in-depth, firsthand knowledge of every company you own whether it is in the
U.S. or anywhere across the globe.

We have structured our equity and fixed-income investment teams to capitalize on
the strength of our investment process and the global reach of our analysts
based around the world. Our global research team is composed of 45 equity
analysts, 27 based in the U.S. and 18 based abroad, and 26 credit research
analysts. Each analyst is assigned one or more specific industries and then
charged with identifying the most attractive investment ideas within these
industries. Our U.S. and non-U.S. equity research analysts are unified into one
team that emphasizes a collaborative process in analyzing securities across the
globe. Credit analysts also share their expertise in each segment of the
fixed-income market and work as part of the same team ensuring that every member
has access to information that may have a material effect on their investment
decisions. As MFS continues to grow and as markets become more complex, we
believe our structure will enable us to maintain a consistent investment process
with the goal of providing strong, long-term investment performance across
market capitalizations, investment disciplines, and country borders for our fund
shareholders.

THINKING GLOBALLY
More companies than ever compete globally and, therefore, we must make
investment decisions knowing what is occurring outside of a company's local
market. This trend plays to the strength of our environment of collaboration
between our analysts and portfolio managers across the globe. The analysts know
the most details about individual companies in specific industries and
geographic regions. The portfolio managers have broader, cross-industry insights
and a wider perspective on companies and industries. Our goal is to make sure
those two sets of perspectives coordinate and work well together. As markets
across the globe become more interdependent, we believe our collaborative
environment allows us to produce solid investment ideas for our portfolios.

BUILDING A NETWORK
Simply put, we believe our structure assures that our analysts maintain their
peripheral vision rather than becoming too immersed in a specific segment of the
market. We do not believe that analysts and portfolio managers -- no matter how
talented they may be -- can succeed by working in a vacuum. Through the latest
technology available, our entire research team meets frequently via video and
telephone teleconferences, email, and PDAs (Personal Digital Assistants). When
we hire new analysts, we require them to spend an average of one year in Boston
to learn MFS' culture and to build relationships with their peers. We believe
the interaction among our analysts is the key to making our collaborative
process work towards delivering superior long term investment performance for
our fund shareholders. Our analysts work out of four research offices in Boston,
London, Singapore, and Tokyo, and are assigned to specific regions and
industries. They meet regularly with their colleagues to discuss the trends
around the world affecting the companies they cover.

In addition, our equity and fixed-income analysts often visit company
managements as a team. This collaboration is vital because of the different
perspective they bring to their analysis. Because a company's stock price has
tended to follow its earnings over time, our equity research analysts tend to
focus on gauging earnings potential, a company's position within its industry
and its ability to grow its market share. Conversely, our fixed income analysts
will look at stability of a company's cash flow, the value of its assets, and
its capital structure to gauge whether the company can generate enough free cash
flow to pay off its debt. As a result of their collaboration, we believe we're
able to see a more complete view of a company.

WORKING TOGETHER
Our portfolio managers also work closely with the analysts to select the most
appropriate securities for their portfolios from the various recommendations
made by the analysts. Opinions are exchanged and ideas are challenged so that
each member of our team is involved in our investment process. In fact, our
portfolio managers will be the first ones to tell you that many of their best
ideas start with the research analysts. We believe our collaborative approach
also provides us with an effective way to assess risk. Our portfolio managers
are not discouraged from taking on an appropriate level of risk; however we have
rigorous guidelines to assure that the level of risk is measured and monitored
and consistent with the investment philosophies of each of our portfolios. All
told, we believe our culture empowers the members of our investment team to
continue to do their best work and allows them to make better investment
decisions.

As always, we appreciate your confidence in MFS and welcome any questions or
comments you may have.

Respectfully,


/s/ Jeffrey L. Shames

MANAGEMENT REVIEW

[Photo of James J. Calmas]
    James J. Calmas

Dear Shareholders,

For the six months ended April 30, 2003, the trust provided a total return of
6.61% based on its beginning and ending stock market prices and assuming the
reinvestment of any distributions paid during the period. The trust's total
return based on its net asset value (NAV) was 3.04%. This return compares with
those of 2.87% and 11.71%, respectively, for the trust's benchmarks, the Salomon
Brothers Medium Term (1- to 10-year) Treasury Government Sponsored Index (the
Salomon Index), and the J.P. Morgan Non-Dollar Government Bond Index (the Morgan
Index). The Salomon Index measures the performance of medium-term government
bonds. The Morgan Index measures the performance of international government
bonds.

A DECLINING INTEREST RATE ENVIRONMENT
Declining interest rates around the globe were a major driver of fixed-income
performance over the six-month period. Just after the trust's reporting period
began, the U.S. Federal Reserve Board (the Fed) lowered short-term interest
rates on November 6, 2002. The European Central Bank followed with its own
interest rate cuts in early December and in March. Both central banks acted to
stimulate sagging economies. As a result of these rate cuts, yields on most
bonds began to decline. For the period, yields on European bonds, in general,
fell more than those of U.S. bonds. However, most European issues started the
period at higher yield levels than comparable U.S. issues.

POSITIVE RETURNS FROM MORTGAGE-BACKED AND NON-U.S. GOVERNMENT HOLDINGS
Throughout the period, we endeavored to position the trust to pick up as much
yield as possible from our investments in U.S. and foreign government
securities. As we entered the period, yields on U.S. Treasury securities had
already come down somewhat because of increased investor demand for the safety
offered by Treasuries. In seeking to enhance the trust's yield, we maintained a
significant position in mortgage-backed securities. In the first quarter of
2003, we also added to the trust's holdings in foreign government bonds. The
trust benefited from both moves not only through increased income (as compared
to Treasuries), but also through capital appreciation that occurred as yields
overall continued to slip. (The principal value and interest on Treasury
securities are guaranteed by the U.S. government if held to maturity.)

The trust outperformed the Salomon Index over the period because of the strong
returns generated by mortgages and by the international portion of the
portfolio.

The trust underperformed the Morgan Index, which is composed solely of non- U.S.
bonds, over the period largely because most of the trust's overseas holdings are
hedged back into U.S. dollars, while the Morgan Index is totally non-dollar. The
trust hedges most of its overseas holdings in an attempt to minimize the effects
of currency fluctuations and allow the trust's returns to be driven mainly by
bond performance. We believe this strategy has tended to dampen portfolio
volatility. However, a disadvantage of this strategy is that the trust could
underperform non-dollar indices such as the Morgan Index when the dollar
declines, as it has done recently.

Respectfully,

NOTES TO PERFORMANCE SUMMARY

ALL RESULTS ARE HISTORICAL. INVESTMENT RETURN AND PRINCIPAL VALUE WILL
FLUCTUATE, AND SHARES, WHEN SOLD, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL
COST. MORE RECENT RETURNS MAY BE MORE OR LESS THAN THOSE SHOWN. PAST PERFORMANCE
IS NO GUARANTEE OF FUTURE RESULTS.

MARKET VOLATILITY CAN SIGNIFICANTLY AFFECT SHORT-TERM PERFORMANCE, AND MORE
RECENT RETURNS MAY BE DIFFERENT FROM THOSE SHOWN. VISIT WWW.MFS.COM FOR MORE
CURRENT PERFORMANCE RESULTS.

KEY RISK CONSIDERATIONS

Investing in foreign and/or emerging markets securities involves risks relating
to interest rates, currency exchange rates, economic, and political conditions.

The portfolio may invest in derivative securities, which may include futures and
options. These types of instruments can increase price fluctuation.

Because the portfolio invests in a limited number of companies a change in one
security's value may have a more significant effect on the portfolio's value.

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

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

NUMBER OF SHAREHOLDERS

As of April 30, 2003, our records indicate that there are 9,026 registered
shareholders and approximately 54,680 shareholders owning trust shares in
"street" name, such as through brokers, banks, and other financial
intermediaries.

If you are a "street" name shareholder and wish to directly receive our reports,
which contain important information about the trust, please write or call:

        State Street Bank and Trust Company
        c/o MFS Service Center, Inc.
        P.O. Box 55024

DIVIDEND REINVESTMENT AND CASH PURCHASE PLAN

MFS offers a Dividend Reinvestment and Cash Purchase Plan that allows you to
reinvest either all of the distributions paid by the trust or only the long-
term capital gains. Purchases are made at the market price unless that price
exceeds the net asset value (the shares are trading at a premium). If the shares
are trading at a premium, purchases will be made at a discounted price of either
the net asset value or 95% of the market price, whichever is greater. Twice each
year you can also buy shares. Investments in any amount over $100 can be made in
January and July on the 15th of the month or shortly thereafter.

If your shares are in the name of a brokerage firm, bank, or other nominee, you
can ask the firm or nominee to participate in the plan on your behalf. If the
nominee does not offer the plan, you may wish to request that your shares be
re-registered in your own name so that you can participate.

There is no service charge to reinvest distributions, nor are there brokerage
charges for shares issued directly by the trust. However, when shares are bought
on the New York Stock Exchange or otherwise on the open market, each participant
pays a pro rata share of the commissions. The automatic reinvestment of
distributions does not relieve you of any income tax that may be payable (or
required to be withheld) on the distributions.

To enroll in or withdraw from the plan, or if you have any questions, call
1-800-637-2304 any business day from 8 a.m. to 8 p.m. Eastern time. Please have
available the name of the trust and your account and Social Security numbers.
For certain types of registrations, such as corporate accounts, instructions
must be submitted in writing. Please call for additional details. When you
withdraw, you can receive the value of the reinvested shares in one of two ways:
a check for the value of the full and fractional shares, or a certificate for
the full shares and a check for the fractional shares.

(S)(S) As required, effective November 1, 2001, the trust adopted the provisions
       of the AICPA Audit and Accounting Guide for Investment Companies and
       began amortizing premium on debt securities. The effect of this change
       for the year ended October 31, 2002, was to decrease net investment
       income per share by $0.06, and increase realized and unrealized gains and
       losses per share by $0.06, and decrease the ratio of net investment
       income to average net assets by 0.78%. Per share ratios and supplemental
       data for periods prior to November 1, 2001 have not been restated to
       reflect this change in presentation.

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 trust 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 - Bonds and other fixed income securities (other than
short-term obligations) of U.S. issuers in the trust's portfolio are valued at
an evaluated bid price on the basis of quotes from brokers and dealers or on the
basis of valuations furnished by a pricing service. 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. Forward Contracts will be valued using a
pricing model taking into consideration market data from an external pricing
source. Use of the pricing services has been approved by the Board of Trustees.
All other securities (other than short-term obligations), futures contracts and
options in the trust's portfolio for which the principal market is one or more
securities or commodities exchanges (whether domestic or foreign) will be valued
at the last reported sale price or at the settlement price prior to the
determination (or if there has been no current sale, at the closing bid price)
on the primary exchange on which such securities, futures contracts or options
are traded; but if a securities exchange is not the principal market for
securities, such securities will, if market quotations are readily available, be
valued at current bid prices. Short-term obligations in the trust's portfolio
are valued at amortized cost, which constitutes fair value as determined by the
Board of Trustees. Short-term obligations with a remaining maturity in excess of
60 days will be valued upon dealer supplied valuations. Portfolio investments
for which market quotations are not readily available, or where values have been
materially affected by events occurring after the close of their primary markets
are valued at fair value as determined in good faith by or at the direction of
the Board of Trustees.

Repurchase Agreements - The trust may enter into repurchase agreements with
institutions that the trust's investment adviser has determined are
creditworthy. Each repurchase agreement is recorded at cost. The trust requires
that the securities collateral in a repurchase transaction be transferred to the
custodian in a manner sufficient to enable the trust to obtain those securities
in the event of a default under the repurchase agreement. The trust 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 trust under each such
repurchase agreement. The trust 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 - 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. 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.

Deferred Trustee Compensation - Under a Deferred Compensation Plan (the Plan)
independent Trustees may elect to defer receipt of all or a portion of their
annual compensation. Deferred amounts are treated as though equivalent dollar
amounts had been invested in shares of the trust or other MFS trust selected by
the Trustee. Deferred amounts represent an unsecured obligation of the trust
until distributed in accordance with the Plan. Included in other assets and
accrued expenses and other liabilities is $15,217 of Deferred Trustee
Compensation.

Futures Contracts - The trust may enter into futures contracts for the delayed
delivery of securities or currency, or contracts based on financial indices at a
fixed price on a future date. In entering such contracts, the trust is required
to deposit with the broker either in cash or securities an amount equal to a
certain percentage of the contract amount. Subsequent payments are made or
received by the trust each day, depending on the daily fluctuations in the value
of the contract, and are recorded for financial statement purposes as unrealized
gains or losses by the trust. The trust's, investment in futures contracts is
designed to hedge against anticipated future changes in interest or exchange
rates or securities prices. Investments in interest rate futures for purposes
other than hedging may be made to modify the duration of the portfolio without
incurring the additional transaction costs involved in buying and selling the
underlying securities. Investments in currency futures for purposes other than
hedging may be made to change the trust's relative position in one or more
currencies without buying and selling portfolio assets. Investments in index
contracts or contracts on related options for purposes other than hedging, may
be made when the trust has cash on hand and wishes to participate in anticipated
market appreciation while the cash is being invested. Should interest or
exchange rates or securities prices move unexpectedly, the trust may not achieve
the anticipated benefits of the futures contracts and may realize a loss.

Security Loans - State Street Bank and Trust Company ("State Street") as lending
agent, may loan the securities of the trust to certain qualified institutions
(the "Borrowers") approved by the trust. 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 trust with
indemnification against Borrower default. The trust bears the risk of loss with
respect to the investment of cash collateral.

Cash collateral is invested in 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 trust and the lending agent. On loans
collateralized by U.S. Treasury securities, a fee is received from the Borrower,
and is allocated between the trust 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 April 30, 2003 there
were no securities on loan.

Forward Foreign Currency Exchange Contracts - The trust may enter into forward
foreign currency exchange contracts for the purchase or sale of a specific
foreign currency at a fixed price on a future date. Risks may arise upon
entering into these contracts from the potential inability of counterparties to
meet the terms of their contracts and from unanticipated movements in the value
of a foreign currency relative to the U.S. dollar. The trust may enter into
forward foreign currency exchange contracts for hedging purposes as well as for
non-hedging purposes. For hedging purposes, the trust may enter into contracts
to deliver or receive foreign currency it will receive from or require for its
normal investment activities. The trust may also use contracts in a manner
intended to protect foreign currency-denominated securities from declines in
value due to unfavorable exchange rate movements. For non-hedging purposes, the
trust may enter into contracts with the intent of changing the relative exposure
of the trust's portfolio of securities to different currencies to take advantage
of anticipated changes. The forward foreign currency exchange contracts are
adjusted by the daily exchange rate of the underlying currency and any gains or
losses are recorded as unrealized until the contract settlement date. On
contract settlement date, the gains or losses are recorded as realized gains or
losses on foreign currency transactions.

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 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.
Some securities may be purchased on a "when-issued" or "forward delivery" basis,
which means that the securities will be delivered to the trust at a future date,
usually beyond customary settlement time.

The trust 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 1.0%. The trust
holds, and maintains until settlement date, cash or high-grade debt obligations
in an amount sufficient to meet the purchase price, or the trust 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 trusts'
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 trust may enter into "TBA" (to be announced) 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 trust's custody fee is reduced according to an
arrangement that measures the value of cash deposited with the custodian by the
trust. This amount is shown as a reduction of total expenses on the Statement of
Operations.

Tax Matters and Distributions - The trust'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 trust
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 currency transactions, mortgage-backed securities, derivatives,
real estate investment trusts, defaulted bonds, capital losses, and amortization
and accretion on debt securities.

The tax character of distributions declared for the years ended October 31, 2002
and October 31, 2001 was as follows:

As of October 31, 2002, the components of distributable earnings (accumulated
losses) on a tax basis were as follows:

       Undistributed ordinary income                      $  3,974,205

(3) Transactions with Affiliates
Investment Adviser - The trust 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 0.32% of
the trust's average daily net assets and 5.65% of investment income.

The trust 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
trust, all of whom receive remuneration for their services to the trust from
MFS. Certain officers and Trustees of the trust are officers or directors of MFS
and MFS Service Center, Inc. (MFSC). On January 1, 2002, the Trustees terminated
the Independent Trustee unfunded defined benefit plan for active Trustees and
converted it to an unfunded retirement benefit deferral plan for active
Trustees. Under the new plan, the unfunded pension liability was converted into
an equivalent value of notional shares of the trust that will fluctuate with the
performance of the trust. Included in Trustees' compensation is a net decrease
of $50,142 as a result of the change in the trust's pension liability under this
plan and a pension expense of $66,343 for inactive trustees for the six months
ended April 30, 2003.

Administrator - The trust has an administrative services agreement with MFS to
provide the trust with certain financial, legal, shareholder communications,
compliance, and other administrative services. As a partial reimbursement for
the cost of providing these services, the trust pays MFS an administrative fee
at the following annual percentages of the trust'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%

Transfer Agent - MFSC acts as registrar and dividend disbursing agent for the
Trust. The agreement provides that the Trust will pay MFSC an account
maintenance fee of no more than $9.00 and a dividend services fee of $0.75 per
reinvestment and will reimburse MFSC for reasonable out-of-pocket expenses.

(4) Portfolio Securities
Purchases and sales of investments, other than purchased option transactions and
short-term obligations, were as follows:

(5) Shares of Beneficial Interest
The trust's Declaration of Trust permits the Trustees to issue an unlimited
number of full and fractional shares of beneficial interest. The Trustees have
authorized 135,059,966 full and fractional shares of beneficial interest and
have authorized the repurchase by the trust of up to 10% of its own shares of
beneficial interest. No shares of beneficial interest were purchased by the
trust during the period ended April 30, 2003. The trust repurchased 480,000
shares of beneficial interest during the year ended October 31, 2002, at an
average price per shares of $6.67 and a weighted average discount of 8.54% per
share. Transactions in trust shares were as follows:

(6) Line of Credit
The trust 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. In addition, a commitment fee, based on the average daily unused
portion of the line of credit, is allocated among the participating funds at the
end of each quarter. The commitment fee allocated to the trust for the six
months ended April 30, 2003, was $3,962. The trust had no borrowings during the
period.

(7) Financial Instruments
The trust 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 forward foreign currency exchange contracts, and
futures contracts. The notional or contractual amounts of these instruments
represent the investment the trust 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.

At April 30, 2003, the trust had sufficient cash and/or securities to cover any
commitments under these contracts.

(8) Change in Accounting Principle
As required, effective November 1, 2001, the trust adopted the provisions of the
AICPA Audit and Accounting Guide for Investment Companies and began amortizing
premium and accreting market discount on debt securities. Prior to November 1,
2001, the trust did not amortize premium nor accrete market discount on debt
securities. The cumulative effect of this accounting change had no impact on
total net assets of the trust, but resulted in a $27,387,322 reduction in cost
of securities and a corresponding $27,387,322 increase in net unrealized
appreciation, based on securities held by the trust on November 1, 2001.

The Trust holds annual shareholder meetings for the purpose of electing
Trustees, and Trustees are elected for fixed terms. The Board of Trustees
currently is divided into three classes, each having a term of three years. Each
year the term of one class expires. Each Trustee's term of office expires on the
date of the third annual meeting following the election to office of the
Trustee's class. Each Trustee will serve until next elected or his or her
earlier death, resignation, retirement or removal.

Messrs. Shames, Cohn, Sherratt and Smith, and Ms. O'Neill have served in their
capacity as Trustee of the Trust continuously since originally elected or
appointed. Messrs. Ballen, Gutow, Ives, Perera and Poorvu, and Ms. Smith were
elected by shareholders and have served as Trustees of the Trust since January
1, 2002. Mr. Parke has served as Trustee of the Trust since January 1, 2002.

Each of the Trust's Trustees and officers holds comparable positions with
certain other funds of which MFS or a subsidiary is the investment adviser or
distributor and, in the case of the officers, with certain affiliates of MFS.
Each Trustee serves as a board member of 112 funds within the MFS Family of
Funds.

The Statement of Additional Information contains further information about the
Trustees and is available without charge upon request, by calling
