- ----------
(1)  "Other Expenses" is based on Class A expenses incurred during the period
     ended May 31, 1997.

(2)  Each Fund has an expense offset arrangement which reduces the Fund's
     custodian fee based upon the amount of cash maintained by the Fund with its
     custodian and dividend disbursing agent, and may enter into other such
     arrangements and directed brokerage arrangements (which would also have the
     effect of reducing the Fund's expenses). Any such fee reductions are not
     reflected under "Other Expenses."

(3)  MFS has voluntarily agreed to bear, subject to reimbursement by the
     Emerging Markets Equity Fund, until December 31, 2005, expenses of Class I
     shares of the Fund such that "Other Expenses" of the Emerging Markets
     Equity Fund's Class I shares do not exceed 0.75%, respectively, of the
     Fund's average daily net assets on an annualized basis. This arrangement
     may be terminated or revised by MFS at any time. Absent this expense
     arrangement, "Other Expenses" and "Total Operating Expenses" for the
     Emerging Markets Equity Fund's Class I shares would have been 0.74% and
     1.99%, respectively.

ELIGIBLE PURCHASERS

Class I shares of each Fund are available for purchase only by the following
purchasers ("Eligible Purchasers"):

(i)   certain retirement plans established for the benefit of employees of
      Massachusetts Financial Services Company ("MFS"), the Fund's investment
      adviser, and employees of MFS' affiliates;

(ii)  any fund distributed by MFS Fund Distributors, Inc. ("MFD"), the Fund's
      distributor, if the fund seeks to achieve its investment objective by
      investing primarily in shares of the Fund and other funds distributed by
      MFD;

(iii) any retirement plan, endowment or foundation which (a) purchases shares
      directly through MFD (rather than through a third party broker or
      dealer or other financial intermediary); (b) has, at the time of purchase
      of Class I shares, aggregate assets of at least $100 million; and (c)
      invests at least $10 million in Class I shares of the Fund either alone or
      in combination with investments in Class I shares of other MFS funds
      distributed by MFD (additional investments may be made in any amount);
      provided that MFD may accept purchases from smaller plans, endowments or
      foundations or in smaller amounts if it believes, in its sole discretion,
      that such entity's aggregate assets will equal or exceed $100 million, or
      that such entity will make additional investments which will cause its
      total investment to equal or exceed $10 million, within a reasonable 
      period of time; and

(iv)  bank trust departments which initially invest, on behalf of their trust
      clients, at least $100,000 in Class I shares of the Fund (additional
      investments may be made in any amount); provided that MFD may accept
      smaller initial purchases if it believes, in its sole discretion, that the
      bank trust department will make additional investments, on behalf of its
      trust clients, which will cause its total investment to equal or exceed
      $100,000 within a reasonable period of time.

In no event will a Fund, MFS, MFD or any of their affiliates pay any sales
commissions or compensation to any third party in connection with the sale of
Class I shares; the payment of any such sales commission or compensation would,
under the Fund's policies, disqualify the purchaser as an eligible investor of
Class I shares.

SHARE CLASSES OFFERED BY THE FUNDS

     Four classes of shares of each Fund currently are offered for sale, Class A
shares, Class B shares, Class C shares and Class I shares. Class I shares are
available for purchase only by Eligible Purchasers, as defined above, and are
described in this Supplement. Class A shares, Class B shares and Class C shares
are described in the Funds' Prospectus and are available for purchase by the
general public.

     Class A shares are offered at net asset value plus an initial sales charge
up to a maximum of 4.75% of the offering price (or a contingent deferred sales
charge (a "CDSC") upon redemption of 1.00% during the first year in the case of
purchases of $1 million or more and certain purchases by retirement plans), and
are subject to an annual distribution fee and service fee up to a maximum of
0.50% per annum. Class B shares are offered at net asset value without an
initial sales charge but are subject to a CDSC upon redemption (declining from
4.00% during the first year to 0% after six years) and an annual distribution
fee and service fee up to a maximum of 1.00% per annum; Class B shares convert
to Class A shares approximately eight years after purchase. Class C shares are
offered at net asset value without an initial sales charge but are subject to a
CDSC upon redemption of 1.00% during the first year and an annual distribution
fee and service fee up to a maximum of 1.00% per annum. Class I shares are
offered at net asset value without an initial sales charge or CDSC and are not
subject to a distribution or service fee. Class C and Class I shares do not
convert to any other class of shares of the Funds.

OTHER INFORMATION

     Eligible Purchasers may purchase Class I shares only directly through MFD.
Eligible Purchasers may exchange Class I shares of each Fund for Class I shares
of any other MFS Fund available for purchase by such Eligible Purchasers at
their net asset value (if available for sale), and may exchange Class I shares
of the Fund for shares of the MFS Money Market Fund (if available for sale), and
may redeem Class I shares of the Fund at net asset value. Distributions paid by
the Fund with respect to Class I shares generally will be greater than those
paid with respect to Class A shares, Class B shares and Class C shares because
expenses attributable to Class A shares, Class B shares and Class C shares
generally will be higher.

Subject to termination or revision at the sole discretion of MFS, MFS has agreed
to bear the expenses of the Emerging Markets Equity Fund ("FEM") such that the
FEM's "Other Expenses" which are defined to include all expenses of FEM except
for management fees, taxes, extraordinary expenses, brokerage and termination
costs and class specific expenses, do not exceed 0.75% per annum of FEM's
average daily net assets (the "Maximum Percentage"). The obligation of MFS to
bear these expenses terminates on the last day of FEM's fiscal year in which
FEM's "Other Expenses" are less than or equal to the Maximum Percentage. The
payments made by MFS on behalf of FEM under this arrangement are subject to
reimbursement by FEM to MFS, which will be accomplished by the payment of an
expense reimbursement fee by FEM to MFS computed and paid monthly at a
percentage of its average daily net assets for its then current fiscal year,
with a limitation that immediately after such payment, FEM's "Other Expenses"
will not exceed the Maximum Percentage. This expense reimbursement by FEM to MFS
terminates on the earlier of the date on which payments made by FEM equal the
prior payment of such reimbursable expenses by MFS or December 31, 2005.

                 THE DATE OF THIS SUPPLEMENT IS OCTOBER 1, 1997

(1) Purchases of $1 million or more and certain purchases by retirement plans
    are not subject to an initial sales charge; however, a contingent deferred
    sales charge ("CDSC") of 1% will be imposed on such purchases in the event
    of certain redemption transactions within 12 months following such purchases
    (see "Purchases" below).
 
   
(2) Each Fund has adopted a Distribution Plan for its shares in accordance with
    Rule 12b-1 under the Investment Company Act of 1940, as amended (the "1940
    Act") (the "Distribution Plan"), which provides that it will pay
    distribution/service fees aggregating up to (but not necessarily all of)
    0.50% per annum of the average daily net assets attributable to each Fund's
    Class A shares. Distribution expenses paid under the Plan with respect to
    Class A shares, together with the initial sales charge, may cause long-term
    shareholders to pay more than the maximum sales charge that would have been
    permissible if imposed entirely as an initial sales charge.
 
(3) Each Fund has an expense offset arrangement which reduces the Fund's
    custodian fee based upon the amount of cash maintained by the Fund with its
    custodian and dividend disbursing agent, and may enter into other such
    arrangements and directed brokerage arrangements (which would also have the
    effect of reducing the Fund's expenses). Any such fee reductions are not
    reflected under "Other Expenses."
 
(4) MFS has voluntarily agreed to bear, subject to reimbursement by the Emerging
    Markets Equity Fund, until December 31, 2005, expenses of each class of
    shares of the Fund such that "Other Expenses" of the Emerging Markets Equity
    Fund's Class A shares, Class B shares and Class C shares do not exceed
    0.75%, respectively, of the Fund's average daily net assets on an annualized
    basis. This arrangement may be terminated or revised by MFS at any time (see
    "Information Concerning Shares of the Funds -- Expenses" below). Absent this
    expense arrangement, "Other Expenses" and "Total Operating Expenses" for the
    Emerging Markets Equity Fund's Class A shares would have been 0.70% and
    2.45%, respectively, "Other Expenses" and "Total Operating Expenses" for the
    Emerging Markets Equity Fund's Class B shares would have been 0.73% and
    2.98%, respectively, and "Other Expenses" and "Total Operating Expenses" for
    the Emerging Markets Equity Fund's Class C shares would be 0.72% and 2.97%,
    respectively.
 
(5) Each Fund's Distribution Plan provides that it will pay distribution/service
    fees aggregating up to (but not necessarily all of) 1.00% per annum of the
    average daily net assets attributable to each Fund's Class B and Class C
    shares, respectively, under the Distribution Plan (see "Distribution Plan"
    below). Distribution expenses paid under the Plan with respect to Class B
    and Class C shares, together with any CDSC payable upon redemption of Class
    B and Class C shares, may cause long-term shareholders to pay more than the
    maximum sales charge that would have been permissible if imposed entirely as
    an initial sales charge.

                                 2.   THE FUNDS
- --------------------------------------------------------------------------------

   
     Each Fund is a diversified series of the Trust, an open-end management
investment company which was organized as a business trust under the laws of The
Commonwealth of Massachusetts in 1985. The Trust presently consists of four
series, each of which represents a portfolio with separate investment objectives
and policies. This Prospectus relates to the International Growth Fund, the
International Growth and Income Fund and the Emerging Markets Equity Fund.
Shares of the other series of the Trust, MFS Government Mortgage Fund, are
offered and sold pursuant to a separate prospectus and statement of additional
information. Shares of each Fund are sold continuously to the public and each
Fund then uses the proceeds to buy securities for its portfolio. Three classes
of shares of each Fund currently are offered to the general public. Class A
shares are offered at net asset value plus an initial sales charge up to a
maximum of 4.75% of the offering price (or a CDSC of 1.00% upon redemption
during the first year in the case of certain purchases of $1 million or more and
certain purchases by retirement plans) and are subject to an annual distribution
fee and service fee up to a maximum of 0.50% per annum. Class B shares are
offered at net asset value without an initial sales charge but are subject to a
CDSC upon redemption (declining from 4.00% during the first year to 0% after six
years) and an annual distribution fee and service fee up to a maximum of 1.00%
per annum; Class B shares will convert to Class A shares approximately eight
years after purchase. Class C shares are offered at net asset value without an
initial sales charge but are subject to a CDSC upon redemption of 1.00% during
the first year and an annual distribution fee and service fee up to a maximum of
1.00% per annum. Class C shares do not convert to any other class of shares of a
Fund. In addition, the Fund offers an additional class of shares, Class I
shares, exclusively to certain institutional investors. Class I shares are made
available by means of a separate Prospectus Supplement provided to institutional
investors eligible to purchase Class I shares and are offered at net asset value
without an initial sales charge or CDSC upon redemption and without an annual
distribution and service fee.
    
 
     The Trust's Board of Trustees provides broad supervision over the affairs
of the Funds. The Adviser is responsible for the management of each Fund's
assets (including supervision of the Sub-Adviser) and the officers of the Trust
are responsible for the operations of each Fund. The Adviser manages each
portfolio from day to day in accordance with each Fund's investment objective
and policies. A majority of the Trustees are not affiliated with the Adviser or
the Sub-Adviser. The Trust also offers to buy back (redeem) shares of each Fund
from shareholders at any time at net asset value, less any applicable CDSC.

(SECTION)  For the year ended May 31, 1997, MFS voluntarily agreed to bear, 
           subject to reimbursement by the Fund, expenses of each class of 
           shares of the Fund such that expenses, exclusive of management, 
           distribution, service fees, and certain expenses, of the Fund's 
           Class A, Class B, Class C, and Class I shares do not exceed 0.75%, 
           respectively, of the Fund's average daily net assets on an 
           annualized basis. For the period ended May 31, 1996, MFS voluntarily 
           agreed to maintain, subject to reimbursement by the Fund, total 
           expenses of the Fund at not more than 2.50%, 3.07%, and 3.00%
           of average daily net assets for Class A, Class B, and Class C shares,
           respectively. To the extent actual expenses were over/under these
           limitations, the net investment income (loss) per share and the 
           ratios would have been:

                     4.   INVESTMENT OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------
 
     Each Fund has a different investment objective which it pursues through
separate investment policies, as described below. The differences in objectives
and policies among the Funds can be expected to affect the market and financial
risk to which each Fund is subject and the performance of each Fund. The
investment objective and policies of each Fund may, unless otherwise
specifically stated, be changed by the Trustees of the Trust without a vote of
the shareholders. A change in a Fund's objective may result in the Fund having
an investment objective different from the objective which the shareholder
considered appropriate at the time of investment in the Fund. Any investment
involves risk and there is no assurance that the investment objective of any
Fund will be achieved.

     INTERNATIONAL GROWTH FUND -- The International Growth Fund's investment
objective is to seek capital appreciation. The Fund seeks to achieve its
objective by investing, under normal market conditions, at least 65% of its
total assets in equity securities of companies whose principal activities are
outside the U.S. growing at rates expected to be well above the growth rate of
the overall U.S. economy. The foreign growth securities in which the Fund may
invest include securities of more established companies which represent
opportunities for long-term growth. See "Investment Techniques -- Foreign Growth
Securities" below. The selection of securities is made solely on the basis of
potential for capital appreciation. Dividend and interest income from portfolio
securities, if any, is incidental to the Fund's investment objective of capital
appreciation.
 
     The Fund may invest up to 25% of its net assets in securities of issuers
whose principal activities are located in emerging market countries. See
"Investment Techniques -- Emerging Market Securities" below.
 
     While the Fund intends to invest primarily in equity securities, the Fund
may also invest up to 35% of its net assets (and generally expects to invest not
more than 20% of its net assets) in fixed income securities of government,
government-related, supranational and corporate issuers whose principal
activities are outside the U.S., including up to 10% of its net assets in fixed
income securities rated Ba or lower by Moody's Investors Service, Inc.
("Moody's") or BB or lower by Standard & Poor's Ratings Services ("S&P"), Fitch
Investors Service, Inc. ("Fitch") or Duff & Phelps Credit Rating Co. ("Duff &
Phelps") and comparable unrated securities. See "Risk Factors -- Lower Rated
Fixed Income Securities" below. The Adviser and Sub-Adviser consider a variety
of factors in selecting fixed income securities to achieve capital appreciation,
including the creditworthiness of issuers, interest rates and currency exchange
rates.
 
   
     INTERNATIONAL GROWTH AND INCOME FUND -- The International Growth and Income
Fund's investment objective is to seek capital appreciation and current income.
The Fund seeks to achieve its objective by investing primarily in equity
securities of issuers whose principal activities are outside the U.S.
    
 
   
     The Fund will invest, under normal market conditions, at least 65% of its
total assets (and generally expects to invest a substantial portion of its total
assets) in equity securities of foreign "blue chip" companies and foreign growth
companies. See "Investment Techniques -- Foreign Growth Securities" below. The
Fund considers a security to be "blue chip" if the total equity market
capitalization of the issuer is at least U.S. $5 billion. It is expected that
the Fund's equity securities will include income producing securities.
    
 
     The Fund may invest up to 10% of its net assets in securities of issuers
whose principal activities are located in emerging market countries. See
"Investment Techniques -- Emerging Market Securities" below.
 
     EMERGING MARKETS EQUITY FUND -- The Emerging Markets Equity Fund's
investment objective is to seek capital appreciation. The Fund seeks to achieve
its objective by investing, under normal market conditions, at least 65% of its
total assets in equity securities of issuers whose principal activities are
located in emerging market countries. The Adviser and the Sub-Adviser expect to
take a global approach to portfolio management by weighting the Fund's
investments towards countries in Latin America, Asia, Africa, the Middle East
and the developing countries of Europe, primarily in Eastern Europe. See
"Investment Techniques -- Emerging Market Securities" below. The selection of
securities is made solely on the basis of potential for capital appreciation.
Dividend and interest income from portfolio securities, if any, is incidental to
the Fund's investment objective of capital appreciation.
 
     While the Fund intends to invest primarily in equity securities, the Fund
may also invest less than 35% of its net assets in fixed income securities of
government, government-related, supranational and corporate issuers whose
principal activities are outside the U.S., rated Ba or lower by Moody's or BB or
lower by S&P, Fitch or Duff & Phelps and comparable unrated securities. See
"Risk Factors -- Lower Rated Fixed Income Securities" below. The Adviser and the
Sub-Adviser consider a variety of factors in selecting fixed income securities
to achieve capital appreciation, including the creditworthiness of issuers,
interest rates and currency exchange rates.
 
                               ------------------
 
     The Funds do not intend to emphasize any particular country or region in
making their investments, but
 
                                        6
<PAGE>   20
 
under normal market conditions, each Fund will be invested in at least three
countries (outside the U.S.) and will not invest more than 50% of its net assets
in issuers whose principal activities are located in a single country. See "Risk
Factors -- Investments in One or a Limited Number of Countries" below.
Currently, none of the Funds expect to invest more than 25% of their net assets
in issuers whose principal activities are located in a single country, except
that the International Growth Fund and the International Growth and Income Fund
generally expect to invest between 15% to 45% of their assets in issuers whose
principal activities are in Japan. Each Fund will seek to reduce risk by
investing its assets in a number of markets and issuers, performing credit
analyses of potential investments and monitoring current developments and trends
in both the international economy and financial markets.
 
     The Adviser and the Sub-Adviser determine where an issuer's principal
activities are located by considering such factors as its country of
organization, the principal trading market for its securities and the source of
its revenues and assets. The issuer's principal activities generally are deemed
to be located in a particular country if: (a) the security is issued or
guaranteed by the government of that country or any of its agencies, authorities
or instrumentalities; (b) the issuer is organized under the laws of, and
maintains a principal office in, that country; (c) the issuer has its principal
securities trading market in that country; (d) the issuer derives 50% or more of
its total revenues from goods sold or services performed in that country; or (e)
the issuer has 50% or more of its assets in that country.
 
   
     For temporary defensive reasons, such as during times of international
political or economic uncertainty or turmoil, most or all of each Fund's
investments may be in cash (U.S. dollars, foreign currencies or multinational
currency units) and/or securities that are denominated in U.S. dollars or whose
issuers are domiciled in the U.S. Each Fund is not restricted as to the portions
of its assets which may be invested in securities denominated in a particular
currency and up to 100% of each Fund's net assets may be invested in securities
denominated in foreign currencies and multinational currency units.

                           5.   INVESTMENT TECHNIQUES
- --------------------------------------------------------------------------------
     Consistent with each Fund's investment objective and policies, each Fund
may engage in the following investment techniques, many of which are described
more fully in the SAI. See "Investment Policies and Restrictions" in the SAI.
 
   
     EQUITY SECURITIES:  Each Fund may invest in all types of equity securities,
including the following: common stocks, preferred stocks and preference stocks;
securities such as bonds, warrants or rights that are convertible into stocks;
and depository receipts for those securities. These securities may be listed on
securities exchanges, traded in various over-the-counter markets or have no
organized markets.
    
 
     FOREIGN GROWTH SECURITIES:  Each Fund may invest in securities of foreign
growth companies, including established foreign companies, whose rates of
earnings growth are expected to accelerate because of special factors, such as
rejuvenated management, new products, changes in consumer demand, or basic
changes in the economic environment or which otherwise represent opportunities
for long-term growth. See "Risk Factors" below. It is anticipated that these
companies will primarily be in nations with more developed securities markets,
such as Japan, Australia, Canada, New Zealand and most Western European
countries, including Great Britain.
 
     EMERGING MARKET SECURITIES:  Consistent with each Fund's respective
objective and policies, each Fund may invest in securities of issuers whose
principal activities are located in emerging market countries. Emerging market
countries include any country determined by the Adviser and the Sub-Adviser to
have an emerging market economy, taking into account a number of factors,
including whether the country has a low- to middle-income economy according to
the International Bank for Reconstruction and Development, the country's foreign
currency debt rating, its political and economic stability and the development
of its financial and capital markets. The Adviser and the Sub-Adviser determine
whether an issuer's principal activities are located in an emerging market
country by considering such factors as its country of organization, the
principal trading market for its securities and the source of its revenues and
assets. The issuer's principal activities generally are deemed to be located in
a particular country if: (a) the security is issued or guaranteed by the
government of that country or any of its agencies, authorities or
instrumentalities; (b) the issuer is organized under the laws of, and maintains
a principal office in, that country; (c) the issuer has its principal securities
trading market in that country; (d) the issuer derives 50% or more of its total
revenues from goods sold or services performed in that country; or (e) the
issuer has 50% or more of its assets in that country. See "Risk Factors --
Emerging Markets" below.
 
     FIXED INCOME SECURITIES:  Fixed income securities in which each Fund may
invest include all types of long-or short-term debt obligations, such as bonds,
notes, bills, debentures, loans, loan assignments and commercial paper. Each
Fund may invest in emerging market fixed income securities, which, in addition
to the securities identified above, may take the form of interests issued by
entities organized and operated for the purpose of
 
                                        7
<PAGE>   21
 
restructuring the investment characteristics of instruments issued by emerging
market country issuers. Fixed income securities in which each Fund may invest
include securities in the lower rating categories of recognized rating agencies
and comparable unrated securities. See "Risk Factors" below. The International
Growth Fund will not invest more than 10% of its net assets, the International
Growth and Income Fund will not invest more than 25% of its net assets and the
Emerging Markets Equity Fund will not invest 35% or more of its net assets, in
fixed income securities rated Ba or lower by Moody's or BB or lower by S&P or
Fitch and comparable unrated securities. See "Risk Factors -- Lower Rated Fixed
Income Securities" below. However, because most foreign fixed income securities
are not rated, a Fund will invest in foreign fixed income securities primarily
based on the Adviser's or the Sub-Adviser's credit analysis without relying on
published ratings.
 
     INVESTMENT IN OTHER INVESTMENT COMPANIES:  Each Fund may invest in other
investment companies to the extent permitted by the 1940 Act and applicable
state securities laws (i) as a means by which the Fund may invest in securities
of certain countries which do not otherwise permit investment, (ii) as a means
to purchase thinly traded securities of emerging market companies, or (iii) when
the Adviser or the Sub-Adviser believes such investments may be more
advantageous to the Fund than a direct market purchase of securities. If a Fund
invests in such investment companies, the Fund's shareholders will bear not only
their proportionate share of the expenses of the Fund (including operating
expenses and the fees of the Adviser) but also will indirectly bear similar
expenses of the underlying investment companies.
 
     PRIVATIZATIONS:  The governments in some countries, including emerging
market countries, have been engaged in programs of selling part or all of their
stakes in government owned or controlled enterprises ("privatizations"). Each
Fund may invest in privatizations. In certain countries, the ability of foreign
entities to participate in privatizations may be limited by local law and the
terms on which the foreign entities may be permitted to participate may be less
advantageous than those afforded local investors.
 
     DEPOSITARY RECEIPTS:  Each Fund may invest in American Depositary Receipts
("ADRs"), Global Depositary Receipts ("GDRs") and other types of depositary
receipts. ADRs are certificates issued by a U.S. depository (usually a bank) and
represent a specified quantity of shares of an underlying non-U.S. stock on
deposit with a custodian bank as collateral. GDRs and other types of depositary
receipts are typically issued by foreign banks or trust companies and evidence
ownership of underlying securities issued by either a foreign or a U.S. company.
Generally, ADRs are in registered form and are designed for use in U.S.
securities markets and GDRs are in bearer form and are designed for use in
foreign securities markets. For the purposes of a Fund's policy to invest a
certain percentage of its assets in foreign securities, the investments of a
Fund in ADRs, GDRs and other types of depositary receipts are deemed to be
investments in the underlying securities.
 
     BRADY BONDS: Each Fund may invest in Brady Bonds, which are securities
created through the exchange of existing commercial bank loans to public and
private entities in certain emerging markets for new bonds in connection with
debt restructurings under a debt restructuring plan introduced by former U.S.
Secretary of the Treasury, Nicholas F. Brady (the "Brady Plan"). Brady Plan debt
restructurings have been implemented to date in Argentina, Brazil, Bulgaria,
Costa Rica, Dominican Republic, Ecuador, Jordan, Mexico, Nigeria, Panama, the
Philippines, Poland, Uruguay and Venezuela. Brady Bonds have been issued only
recently, and for that reason do not have a long payment history. Brady Bonds
may be collateralized or uncollateralized, are issued in various currencies (but
primarily the U.S. dollar) and are actively traded in over-the-counter secondary
markets. U.S. dollar-denominated, collateralized Brady Bonds, which may be fixed
rate bonds or floating-rate bonds, are generally collateralized in full as to
principal by U.S. Treasury zero coupon bonds having the same maturity as the
bonds. Brady Bonds are often viewed as having three or four valuation
components: the collateralized repayment of principal at final maturity; the
collateralized interest payments; the uncollateralized interest payments; and
any uncollateralized repayment of principal at maturity (these uncollateralized
amounts constitute the "residual risk"). In light of the residual risk of Brady
Bonds and the history of defaults of countries issuing Brady Bonds with respect
to commercial bank loans by public and private entities, investments in Brady
bonds may be viewed as speculative.
 
     STRUCTURED SECURITIES:  Each Fund may invest a portion of its assets in
entities organized and operated solely for the purpose of restructuring the
investment characteristics of sovereign debt obligations. This type of
restructuring involves the deposit with, or purchase by, an entity, such as a
corporation or trust, of specified instruments (such as commercial bank loans or
Brady Bonds) and the issuance by that entity of one or more classes of
securities ("Structured Securities") backed by, or representing interests in,
the underlying instruments. The cash flow on the underlying instruments may be
apportioned among the newly issued Structured Securities to create securities
with different investment characteristics, such as varying maturities, payment
priorities and interest rate provisions, and the extent of the payments made
with respect to Structured Securities is dependent on the extent of the cash
flow on the underlying instruments. Because Structured Securities of the type in
which each Fund anticipates it will invest typically involve no credit
enhancement, their credit risk generally will be equivalent to that of the
underlying instruments. Each Fund is permitted to invest in a class of
Structured Securities that is either subordinated or unsubordinated to
 
                                        8
<PAGE>   22
 
the right of payment of another class. Subordinated Structured Securities
typically have higher yields and present greater risks than unsubordinated
Structured Securities. Structured Securities are typically sold in private
placement transactions, and there currently is no active trading market for
Structured Securities.
 
     REPURCHASE AGREEMENTS:  Each Fund may enter into repurchase agreements in
order to earn income on available cash or as a temporary defensive measure.
Under a repurchase agreement, a Fund acquires securities subject to the seller's
agreement to repurchase at a specified time and price. If the seller becomes
subject to a proceeding under the bankruptcy laws or its assets are otherwise
subject to a stay order, the Fund's right to liquidate the securities may be
restricted (during which time the value of the securities could decline). As
discussed in the SAI, each Fund has adopted certain procedures intended to
minimize risk. Foreign repurchase agreements may be less well secured than U.S.
repurchase agreements, and may be denominated in foreign currencies. They may
also involve greater risk of loss if the counterparty defaults. Some
counterparties in these transactions may be less creditworthy than those in U.S.
markets.
 
     ZERO COUPON BONDS, DEFERRED INTEREST BONDS AND PIK BONDS:  Fixed income
securities in which each Fund may invest also include zero coupon bonds,
deferred interest bonds and bonds on which the interest is payable in kind ("PIK
bonds"). Zero coupon and deferred interest bonds are debt obligations which are
issued or purchased at a significant discount from face value. The discount
approximates the total amount of interest the bonds will accrue and compound
over the period until maturity or the first interest payment date at a rate of
interest reflecting the market rate of the security at the time of issuance.
While zero coupon bonds do not require the periodic payment of interest,
deferred interest bonds provide for a period of delay before the regular payment
of interest begins. PIK bonds are debt obligations which provide that the issuer
thereof may, at its option, pay interest on such bonds in cash or in the form of
additional debt obligations. Such investments benefit the issuer by mitigating
its need for cash to meet debt service, but also require a higher rate of return
to attract investors who are willing to defer receipt of such cash. Such
investments may experience greater volatility in market value due to changes in
interest rates and other factors than debt obligations which make regular
payments of interest. Each Fund will accrue income on such investments for tax
and accounting purposes, as required, which is distributable to shareholders and
which, because no cash is received at the time of accrual, may require the
liquidation of other portfolio securities under disadvantageous circumstances to
satisfy the Fund's distribution obligations.
 
   
     INDEXED SECURITIES:  Each Fund may invest in indexed securities whose value
is linked to foreign currencies, interest rates, commodities, indices or other
financial indicators. Most indexed securities are short to intermediate term
fixed income securities whose values at maturity (i.e., principal value) or
interest rates rise or fall according to changes in the value of one or more
specified underlying instruments. Indexed securities may be positively or
negatively indexed (i.e., their principal value or interest rates may increase
or decrease if the underlying instrument appreciates), and may have return
characteristics similar to direct investments in the underlying instrument or to
one or more options on the underlying instrument. Indexed securities may be more
volatile than the underlying instrument itself and could involve the loss of all
or a portion of the principal amount of the instrument.
    
 
   
     LOANS AND OTHER DIRECT INDEBTEDNESS:  Each Fund may invest a portion of its
assets in loans. By purchasing a loan, a Fund acquires some or all of the
interest of a bank or other lending institution in a loan to a corporate,
government or other borrower. Many such loans are secured, and most impose
restrictive covenants which must be met by the borrower. These loans are made
generally to finance internal growth, mergers, acquisitions, stock repurchases,
leveraged buy-outs and other corporate activities. Such loans may be in default
at the time of purchase. Each Fund may also purchase trade or other claims
against companies, which generally represent money owed by the company to a
supplier of goods and services. These claims may also be purchased at a time
when the company is in default. Certain of the loans acquired by a Fund may
involve revolving credit facilities or other standby financing commitments which
obligate the Fund to pay additional cash on a certain date or on demand.
    
 
     The highly leveraged nature of many such loans may make such loans
especially vulnerable to adverse changes in economic or market conditions. Loans
and other direct investments may not be in the form of securities or may be
subject to restrictions on transfer, and only limited opportunities may exist to
resell such instruments. As a result, a Fund may be unable to sell such
investments at an opportune time or may have to resell them at less than fair
market value. For a further discussion of loans and the risks related to
transactions therein, see the SAI.
 
   
     RESTRICTED SECURITIES: Each Fund may purchase securities that are not
registered under the Securities Act of 1933 (the "1933 Act") ("restricted
securities"), including those that can be offered and sold to "qualified
institutional buyers" under Rule 144A under the 1933 Act ("Rule 144A
securities"). A determination is made based upon a continuing review of the
trading markets for a specific Rule 144A security, whether such security is
illiquid and thus subject to a Fund's limitations on invest-
    
 
                                        9
<PAGE>   23
 
   
ing not more than 15% of its net assets in illiquid investments. The Board of
Trustees has adopted guidelines and delegated to the Adviser the daily function
of determining and monitoring liquidity of restricted securities. The Board,
however, retains oversight, focusing on factors, such as valuation, liquidity
and availability of information. Investing in Rule 144A securities could have
the effect of decreasing the level of liquidity in a Fund's portfolio to the
extent that qualified institutional buyers become for a time uninterested in
purchasing Rule 144A securities held in the Fund's portfolio. Subject to each
Fund's 15% limitation on investments in illiquid investments, a Fund may also
invest in restricted securities that may not be sold under Rule 144A, which
presents certain risks. As a result, a Fund might not be able to sell these
securities when the Adviser or Sub-Adviser wishes to do so, or might have to
sell them at less than fair value. In addition, market quotations are less
readily available. Therefore, judgment may at times play a greater role in
valuing these securities than in the case of unrestricted securities.
    
 
     LENDING OF PORTFOLIO SECURITIES:  Each Fund may seek to increase its income
by lending portfolio securities under present regulatory policies, including
those of the Board of Governors of the Federal Reserve System and the SEC. Such
loans will usually be made only to member banks of the Federal Reserve System
and member firms (and subsidiaries thereof) of the New York Stock Exchange, and
would be required to be secured continuously by collateral in cash, irrevocable
letters of credit or U.S. Government securities maintained on a current basis at
an amount at least equal to the market value of the securities loaned. As with
other extensions of credit there are risks of delay in recovery or even loss of
rights in the collateral should the borrower of the securities fail financially.
However, the loans would be made only to entities deemed by the Adviser or the
Sub-Adviser to be of good standing, and when, in the judgment of the Adviser or
the Sub-Adviser, the consideration which can be earned currently from securities
loans of this type justifies the attendant risk. If the Adviser or the
Sub-Adviser determines to make securities loans, it is intended that the value
of the securities loaned would not exceed 30% of the value of the relevant
Fund's total assets.
 
   
     WHEN-ISSUED OR FORWARD DELIVERY SECURITIES:  Securities may be purchased on
a "when-issued" or on a "forward delivery" basis, which means that the
obligations will be delivered to a Fund at a future date usually beyond
customary settlement time. The commitment to purchase a security for which
payment will be made on a future date may be deemed a separate security.
Although a Fund is not limited to the amount of securities for which it may have
commitments to purchase on such basis, it is expected that under normal
circumstances, a Fund will not commit more than 10% of its assets to such
purchases. A Fund does not pay for the securities until received or start
earning interest on them until the contractual settlement date. In order to
invest its assets immediately, while awaiting delivery of securities purchased
on such basis, a Fund will hold liquid assets in a segregated account to pay for
the commitment. Although the Funds do not intend to make such purchases for
speculative purposes, purchases of securities on such bases may involve more
risk than other types of purchases. For additional information concerning these
securities, see the SAI.
    
 
   
     OPTIONS ON SECURITIES:  Each Fund may write (sell) covered put and call
options on securities ("Options") and purchase put and call Options on
securities that are traded on foreign and U.S. securities exchanges and over the
counter. A Fund will write such Options for the purpose of increasing its return
and/or protecting the value of its portfolio. Each Fund may also write
combinations of put and call Options on the same security, known as "straddles."
Such transactions can generate additional premium income but also present
increased risk. Each Fund may purchase put or call Options in anticipation of
declines in the value of portfolio securities or increases in the value of
securities to be acquired. However, the writing of Options constitute only a
partial hedge, up to the amount of the premium, less any transaction costs.
    
 
     Each Fund may purchase and sell options that are traded on foreign and U.S.
exchanges, and Options traded over-the-counter with broker-dealers who deal in
these Options. The ability to terminate over-the-counter Options is more limited
than with exchange-traded Options and may involve the risk that broker-dealers
participating in such transactions will not fulfill their obligations. Each Fund
will treat assets used to cover over-the-counter Options as illiquid unless the
dealer is a primary dealer in U.S. Government securities and has given the Fund
the unconditional right to close such Options at a formula price, in which event
only an amount of the cover determined with reference to the formula will be
considered illiquid. Each Fund may also write over-the-counter options with
non-primary dealers, including foreign dealers, and will treat the assets used
to cover these options as illiquid.
 
     Each Fund may also enter into options on the yield "spread," or yield
differential between two securities, a transaction referred to as a "yield
curve" option, for hedging and non-hedging purposes. In contrast to other types
of options a yield curve option is based on the difference between the yields of
designated securities rather than the actual prices of the individual
securities. Yield curve options written by a Fund will be "covered" but could
involve additional risks, as discussed in the SAI.
 
     OPTIONS ON STOCK INDICES:  Each Fund may write (sell) covered call and put
Options and purchase call and put Options on foreign and domestic stock indices
("Options on Stock Indices"). A Fund may write such options for the purpose of
increasing its current income and/or to
 
                                       10
<PAGE>   24
 
protect its portfolio against declines in the value of securities it owns or
increases in the value of securities to be acquired. When a Fund writes an
option on a stock index, and the value of the index moves adversely to the
holder's position, the option will not be exercised, and the Fund will either
close out the option at a profit or allow it to expire unexercised. The Fund
will thereby retain the amount of the premium, less related transaction costs,
which will increase its gross income and offset part of the reduced value of
portfolio securities or the increased cost of securities to be acquired. Such
transactions, however, will constitute only partial hedges against adverse price
fluctuations, since any such fluctuations will be offset only to the extent of
the premium received by the Fund for the writing of the option, less related
transaction costs. In addition, if the value of an underlying index moves
adversely to the Fund's option position, the option may be exercised, and the
Fund will experience a loss which may only be partially offset by the amount of
the premium received.
 
     Each Fund may also purchase put or call options on stock indices in order,
respectively, to hedge its investments against a decline in value or to attempt
to reduce the risk of missing a market or industry segment advance. A Fund's
possible loss in either case will be limited to the premium paid for the option,
plus related transaction costs.
 
     FUTURES CONTRACTS:  Each Fund may enter into contracts for the purchase or
sale for future delivery of contracts based on indices of securities as such
instruments become available for trading or fixed income securities or foreign
currencies ("Futures Contracts"). Such transactions will be entered into for
hedging purposes, in order to protect a Fund's current or intended investments
from the effects of changes in interest or exchange rates, or for non-hedging
purposes to the extent permitted by applicable law. For example, in the event
that an anticipated decrease in the value of portfolio securities occurs as a
result of a decline in the dollar value of foreign currencies in which portfolio
securities are denominated or a general increase in interest rates, the adverse
effects of such changes may be offset, in whole or in part, by gains on Futures
Contracts sold by a Fund. Conversely, the adverse effects of an increase in the
cost of portfolio securities to be acquired, occurring as a result of a rise in
the dollar value of securities denominated in foreign currencies or a decline in
interest rates, may be offset, in whole or in part, by gains on Futures
Contracts purchased by a Fund. Each Fund will incur brokerage fees when it
purchases and sells Futures Contracts, and will be required to maintain margin
deposits. In addition, Futures Contracts entail risks. Although each Fund
believes that use of such contracts will benefit the Fund, if its investment
judgment about the general direction of interest or exchange rates is incorrect,
the Fund's overall performance may be poorer than if it had not entered into any
such contract and the Fund may realize a loss. Transactions entered into for
non-hedging purposes involve greater risk including the risk of losses which are
not offset by gains on other portfolio assets. Each Fund will not enter into any
Futures Contract if immediately thereafter the value of securities and other
obligations underlying all such Futures Contracts would exceed 50% of the value
of its total assets.
 
     OPTIONS ON FUTURES CONTRACTS: Each Fund may purchase and write options on
futures contracts ("Options on Futures Contracts") in order to protect against
declines in the values of portfolio securities or against increases in the cost
of securities to be acquired. Purchases of Options on Futures Contracts may
present less risk in hedging a Fund's portfolio than the purchase or sale of the
underlying Futures Contracts since the potential loss is limited to the amount
of the premium plus related transaction costs, although it may be necessary to
exercise the option to realize any profit, which results in the establishment of
a futures position. The writing of Options on Futures Contracts, however, does
not present less risk than the trading of Futures Contracts and will constitute
only a partial hedge, up to the amount of the premium received. In addition, if
an option is exercised, a Fund may suffer a loss on the transaction. Options on
Futures Contracts may also be entered into for non-hedging purposes, to the
extent permitted under applicable law, which involves greater risks and could
result in losses which are not offset by gains on other portfolio assets.
 
     OPTIONS ON FOREIGN CURRENCIES:  Each Fund may also purchase and write
options on foreign currencies ("Options on Foreign Currencies") for the purpose
of protecting against declines in the dollar value of foreign portfolio
securities and against increases in the dollar cost of foreign securities to be
acquired. As in the case of other types of options, however, the writing of an
Option on Foreign Currency will constitute only a partial hedge, up to the
amount of the premium received, and a Fund may be required to purchase or sell
foreign currencies at disadvantageous exchange rates, thereby incurring losses.
The purchase of an Option on Foreign Currency may constitute an effective hedge
against fluctuations in exchange rates although, in the event of rate movements
adverse to a Fund's position, it may forfeit the entire amount of the premium
paid for the Option plus related transaction costs. Options on Foreign
Currencies to be written or purchased by a Fund will be traded on foreign and
U.S. exchanges or over-the-counter.
 
     FORWARD CONTRACTS:  Each Fund may enter into forward foreign currency
exchange contracts for the purchase or sale of a fixed quantity of a foreign
currency at a future date at a price set at the time of the contract ("Forward
Contracts"). Each Fund may enter into Forward Contracts for hedging purposes as
well as for the non-hedging purpose of increasing the Fund's current income. By
entering into transactions in Forward Con-
 
                                       11
<PAGE>   25
 
tracts, however, a Fund may be required to forego the benefits of advantageous
changes in exchange rates and, in the case of Forward Contracts entered into for
non-hedging purposes, the Fund may sustain losses which will reduce its gross
income. Such transactions, therefore, could be considered speculative. Forward
Contracts are traded over-the-counter, and not on organized commodities or
securities exchanges. As a result, such contracts operate in a manner distinct
from exchange-traded instruments, and their use involves certain risks beyond
those associated with transactions in Futures Contracts or options traded on
exchanges. A Fund may also enter into a Forward Contract on one currency in
order to hedge against risk of loss arising from fluctuations in the value of a
second currency (referred to as a "cross hedge") if, in the judgment of the
Adviser or the Sub-Adviser, a reasonable degree of correlation can be expected
between movements in the values of the two currencies. Each Fund has established
procedures consistent with statements of the SEC and its staff regarding the use
of Forward Contracts by registered investment companies, which requires use of
segregated assets or "cover" in connection with the purchase and sale of such
contracts.
 
   
     SWAPS AND RELATED TRANSACTIONS:  As one way of managing its exposure to
different types of investments, each Fund may enter into interest rate swaps,
currency swaps and other types of available swap agreements, such as caps,
collars and floors. Swaps involve the exchange by a Fund with another party of
cash payments based upon different interest rate indices, currencies and other
prices or rates, such as the value of mortgage prepayment rates. For example, in
the typical interest rate swap, a Fund might exchange a sequence of cash
payments based on a floating rate index for cash payments based on a fixed rate.
Payments made by both parties to a swap transaction are based on a notional
principal amount determined by the parties.
    
 
     Each Fund may also purchase and sell caps, floors and collars. In a typical
cap or floor agreement, one party agrees to make payments only under specified
circumstances, usually in return for payment of a fee by the counterparty. For
example, the purchase of an interest rate cap entitles the buyer, to the extent
that a specified index exceeds a predetermined interest rate, to receive
payments of interest on a contractually-based principal amount from the
counterparty selling such interest rate cap. The sale of an interest rate floor
obligates the seller to make payments to the extent that a specified interest
rate falls below an agreed-upon level. A collar arrangement combines elements of
buying a cap and selling a floor.
 
   
     Swap agreements could be used to shift a Fund's investment exposure from
one type of investment to another. For example, if a Fund agreed to exchange
payments in dollars for payments in foreign currency, in each case based on a
fixed rate, the swap agreement would tend to decrease the Fund's exposure to
U.S. interest rates and increase its exposure to foreign currency and interest
rates. Caps and floors have an effect similar to buying or writing options.
    
 
   
     Swap agreements are sophisticated hedging instruments that typically
involve a small investment of cash relative to the magnitude of risks assumed,
or no investment of cash. As a result, swaps can be highly volatile and may have
a considerable impact on a Fund's performance. Swap agreements are subject to
risks related to the counterparty's ability to perform, and may decline in value
if the counterparty's creditworthiness deteriorates. A Fund may also suffer
losses if it is unable to terminate outstanding swap agreements or reduce its
exposure through offsetting transactions.
    
 
     Swaps, caps, floors and collars are highly specialized activities which
involve certain risks. See the SAI for more information on, and the risks
involved in, these activities.
 
   
     PORTFOLIO TRADING:  The primary consideration in placing portfolio security
transactions is execution at the most favorable prices. Consistent with the
foregoing primary consideration, the Conduct Rules of the National Association
of Securities Dealers, Inc. (the "NASD") and such other policies as the Trustees
may determine, the Adviser may consider sales of shares of the Funds and of the
other investment company clients of MFD, the Funds' distributor, as a factor in
the selection of broker-dealers to execute the Funds' portfolio transactions.
    
 
     From time to time, the Adviser and the Sub-Adviser may direct certain
portfolio transactions to broker-dealer firms which, in turn, have agreed to pay
a portion of a Fund's operating expenses (e.g., fees charged by the custodian of
the Fund's assets). For a further discussion of portfolio trading, see the SAI.
 
   
     While it is not generally each Fund's policy to invest or trade for
short-term profits, each Fund may dispose of a portfolio security whenever the
Adviser or the Sub-Adviser is of the opinion that such security no longer has an
appropriate appreciation potential or when another security appears to offer
relatively greater appreciation potential. Portfolio changes are made without
regard to the length of time a security has been held, or whether a sale would
result in a profit or loss. Therefore, the rate of portfolio turnover is not a
limiting factor when a change in the portfolio is otherwise appropriate.
Transaction costs incurred by each Fund and realized capital gains and losses of
each Fund may be greater than that of a fund with a lesser portfolio turnover
rate.

                               6.   RISK FACTORS
- --------------------------------------------------------------------------------
 
     FOREIGN SECURITIES:  Transactions involving foreign equity or debt
securities or foreign currencies, and transactions entered into in foreign
countries, involve considerations and risks not typically associated with
investing in U.S. markets. These include changes in currency rates, exchange
control regulations, governmental administration or economic or monetary policy
(in the U.S. or abroad) or circumstances in dealings between nations. Costs may
be incurred in connection with conversions between various currencies. Each Fund
may invest up to 100% of its assets in foreign securities which are not traded
on a U.S. exchange. Special considerations may also include more limited
information about foreign issuers, higher brokerage and custody costs, different
or less stringent accounting standards and thinner trading markets. Foreign
securities markets may also be less liquid, more volatile and less subject to
government supervision than in the U.S. Investments in foreign countries could
be affected by other factors including expropriation, confiscatory taxation and
potential difficulties in enforcing contractual obligations and could be subject
to extended settlement periods.
 
     EMERGING MARKETS:  The risks of investing in foreign securities may be
intensified in the case of investments in emerging markets. Securities in
emerging markets may be less liquid and more volatile in price than securities
of comparable domestic issuers. Emerging markets also have different clearance
and settlement procedures, and in certain markets there have been times when
settlements have been unable to keep pace with the volume of securities
transactions, making it difficult to conduct such transactions. Delays in
settlement could result in temporary periods when a portion of the assets of a
Fund is uninvested and no return is earned thereon. The inability of a Fund to
make intended security purchases due to settlement problems could cause the Fund
to miss attractive investment opportunities. Inability to dispose of portfolio
securities due to settlement problems could result in losses to the Fund due to
subsequent declines in value of the portfolio security, a decrease in the level
of liquidity in the Fund's portfolio, or, if the Fund has entered into a
contract to sell the security, in possible liability to the purchaser. Certain
markets may require payment for securities before delivery, and in such markets
the Funds bear the risk that the securities will not be delivered and that the
Funds' payments will not be returned. Securities prices in emerging markets can
be significantly more volatile than in the more developed nations of the world,
reflecting the greater uncertainties of investing in less established markets
and economies. In particular, countries with emerging markets may have
relatively unstable governments, present the risk of nationalization of
businesses, restrictions on foreign ownership, or prohibitions against
repatriation of assets, and may have less protection of property rights than
more developed countries. The economies of countries with emerging markets may
be predominantly based on only a few industries, may be highly vulnerable to
changes in local or global trade conditions, and may suffer from extreme and
volatile debt burdens or inflation rates. Local securities markets may trade a
small number of securities and may be unable to respond effectively to increases
in trading volume, potentially making prompt liquidation of substantial holdings
difficult or impossible at times. Securities of issuers located in countries
with emerging markets may have limited marketability and may be subject to more
abrupt or erratic price movements.
 
     Certain emerging markets may require governmental approval for the
repatriation of investment income, capital or the proceeds of sales of
securities by foreign investors. In addition, if a deterioration occurs in an
emerging market's balance of payments or for other reasons, a country could
impose temporary restrictions on foreign capital remittances. A Fund could be
adversely affected by a delay in obtaining a grant of, or a refusal to grant,
any required governmental approval for repatriation of capital, as well as by
the application to the Fund of any restrictions on investments.
 
     Investment in certain foreign emerging market debt obligations may be
restricted or controlled to varying degrees. These restrictions or controls may
at times preclude investment in certain foreign emerging market debt obligations
and increase the expenses of a Fund. See the SAI for a further discussion of
emerging markets securities as well as the associated risks.
 
     ALLOCATION AMONG EMERGING MARKETS:  Each Fund may allocate all or a portion
of its investments in emerging market securities among the emerging markets of
Latin America, Asia, Africa, the Middle East and the developing countries of
Europe, primarily in Eastern Europe. Each Fund will allocate its investments
among these emerging markets in accordance with the Adviser's and the
Sub-Adviser's determination as to the allocation most appropriate with respect
to the Fund's investment objective and policies. Each Fund may invest its assets
allocated to investment in emerging markets without limitation in any particular
region, and, in accordance with the Adviser's and the Sub-Adviser's investment
discretion, at times may invest all of its assets allocated to investment in
emerging markets in securities of emerging market issuers located in a single
region (e.g., Latin America). To the extent that a Fund's investments are
concentrated in one or a few emerging market regions, the Fund's investment
performance correspondingly will be more dependent upon the economic, political
and social conditions and changes in those regions. The ability of a Fund to
allocate its investments among emerging market regions without restriction may
have
 
                                       13
<PAGE>   27
 
the effect of increasing the volatility of the Fund, as compared to a fund which
limits such allocations.
 
     INVESTMENTS IN ONE OR A LIMITED NUMBER OF COUNTRIES:  Each Fund will seek
to reduce risk by investing its assets in a number of markets and issuers.
However, each Fund may invest up to 50% of its net assets in issuers located in
a single country. To the extent that a Fund invests a significant portion of its
assets in a single or limited number of countries, the Fund's investment
performance correspondingly will be more dependent upon the economic, political
and social conditions and changes in that country or countries, and the risks
associated with investments in such country or countries will be particularly
significant. The ability of a Fund to focus its investments in one or a limited
number of countries may have the effect of increasing the volatility of that
Fund.
 
     EMERGING GROWTH COMPANIES:  Each Fund may invest in securities of emerging
growth companies, including established companies. Investing in emerging growth
companies involves greater risk than is customarily associated with investing in
more established companies. Emerging growth companies often have limited product
lines, markets or financial resources, and they may be dependent on one-person
management. The securities of emerging growth companies may have limited
marketability and may be subject to more abrupt or erratic market movements than
securities of larger, more established companies or the market averages in
general. Similarly, many of the securities offering the capital appreciation
sought by the Funds will involve a higher degree of risk than would established
growth stocks.
 
     FOREIGN CURRENCIES: Because each Fund may invest up to 100% of its asset in
securities denominated in currencies other than the U.S. dollar, and because
each Fund may hold foreign currencies, the value of a Fund's investments, and
the value of dividends and interest earned by a Fund, may be significantly
affected by changes in currency exchange rates. Some foreign currency values may
be volatile, and there is the possibility of governmental controls on currency
exchange or governmental intervention in currency markets, which could adversely
affect the Funds. Although the Adviser and Sub-Adviser may attempt to manage
currency exchange rate risks, there is no assurance that the Adviser and Sub-
Adviser will do so at an appropriate time or that the Adviser and Sub-Adviser
will be able to predict exchange rates accurately. For example, if the Adviser
and Sub-Adviser hedge a Fund's exposure to a foreign currency, and that
currency's value rises, the Fund will lose the opportunity to participate in the
currency's appreciation. Each Fund may hold foreign currency received in
connection with investments in foreign securities, and enter into Forward
Contracts, Futures Contracts and Options on Foreign Currencies when, in the
judgment of the Adviser or Sub-Adviser, it would be beneficial to convert such
currency into U.S. dollars at a later date, based on anticipated changes in the
relevant exchange rates. While the holding of foreign currencies will permit a
Fund to take advantage of favorable movements in the applicable exchange rate,
it also exposes the Fund to risk of loss if such rates move in a direction
adverse to the Fund's position. Such losses could also adversely affect the
Fund's hedging strategies. See the SAI for further discussion of the holding of
foreign currencies as well as the associated risks.
 
     FIXED INCOME SECURITIES:  To the extent a Fund invests in fixed income
securities, the net asset value of the Fund may change as the general levels of
interest rates fluctuate. When interest rates decline, the value of fixed income
securities can be expected to rise. Conversely, when interest rates rise, the
value of fixed income securities can be expected to decline. Each Fund is
subject to no restrictions on the maturities of the fixed income securities it
holds. A Fund's investments in fixed income securities with longer terms to
maturity are subject to greater volatility than the Fund's shorter-term
obligations.
 
     LOWER RATED FIXED INCOME SECURITIES:  Fixed income securities in which each
Fund may invest may be rated Baa by Moody's or BBB by S&P or Fitch (and
comparable unrated securities). For a description of these and other rating
categories, see Appendix B. These securities, while normally exhibiting adequate
protection parameters, have speculative characteristics and changes in economic
conditions or other circumstances are more likely to lead to a weakened capacity
to make principal and interest payments than in the case of higher grade fixed
income securities.
 
     Each Fund may also invest in fixed income securities rated Ba or lower by
Moody's or BB or lower by S&P or Fitch (and comparable unrated securities). No
minimum rating standard is required by any Fund. These securities are considered
speculative and, while generally providing greater yield than investments in
higher rated securities, will involve greater risk of principal and income
(including the possibility of default or bankruptcy of the issuers of such
securities) and may involve greater volatility of price (especially during
periods of economic uncertainty or change) than securities in the higher rating
categories and because yields vary over time, no specific level of income can
ever be assured. These lower rated high yielding fixed income securities
generally tend to be affected by economic changes (and the outlook for economic
growth), short-term corporate and industry developments and the market's
perception of their credit quality (especially during times of adverse
publicity) to a greater extent than higher rated securities, which react
primarily to fluctuations in the general level of interest rates (although these
lower rated securities are also affected by changes in interest rates as
described below). In the past, economic downturns or an increase in interest
rates have, under certain circumstances, caused a higher
 
                                       14
<PAGE>   28
 
incidence of default by the issuers of these securities and may do so in the
future, especially in the case of highly leveraged issuers. During certain
periods, the higher yields on a Fund's lower rated high yielding fixed income
securities are paid primarily because of the increased risk of loss of principal
and income, arising from such factors as the heightened possibility of default
or bankruptcy of the issuers of such securities. Due to the fixed income
payments of these securities, a Fund may continue to earn the same level of
interest income while its net asset value declines due to portfolio losses,
which could result in an increase in the Fund's yield despite the actual loss of
principal. The prices for these securities may be affected by legislative and
regulatory developments. The market for these lower rated fixed income
securities may be less liquid than the market for investment grade fixed income
securities. Furthermore, the liquidity of these lower rated securities may be
affected by the market's perception of their credit quality. Therefore, the
Adviser's and the Sub-Adviser's judgment may at times play a greater role in
valuing these securities than in the case of investment grade fixed income
securities, and it also may be more difficult during times of certain adverse
market conditions to sell these lower rated securities to meet redemption
requests or to respond to changes in the market.
 
     While the Adviser and the Sub-Adviser may refer to ratings issued by
established credit rating agencies, it is not any Fund's policy to rely
exclusively on ratings issued by these rating agencies, but rather to supplement
such ratings with the Adviser's and the Sub-Adviser's own independent and
ongoing review of credit quality. A Fund's achievement of its investment
objective may be more dependent on the Adviser's and the Sub-Adviser's own
credit analysis than in the case of an investment company primarily investing in
higher quality fixed income securities.
 
     Since shares of each Fund represent an investment in securities with
fluctuating market prices, shareholders should understand that the value of
shares of the Fund will vary as the aggregate value of the portfolio securities
of the Fund increases or decreases. However, changes in the value of securities
subsequent to their acquisition will not affect cash or yield to maturity to a
Fund.
 
     TRANSACTIONS IN OPTIONS, FUTURES CONTRACTS AND FORWARD CONTRACTS:  Although
each Fund may enter into transactions in Options, Options on Stock Indices,
Forward Contracts, Futures Contracts, Options on Futures Contracts and Options
on Foreign Currencies for hedging purposes, such transactions nevertheless
involve certain risks. For example, a lack of correlation between the instrument
underlying an option or futures contract and the assets being hedged, or
unexpected adverse price movements, could render a Fund's hedging strategy
unsuccessful and could result in losses. Each Fund also may enter into
transactions in Options, Options on Stock Indices, Forward Contracts, Futures
Contracts and Options on Futures Contracts for other than hedging purposes, to
the extent permitted by applicable law, which involves greater risk. In
particular, such transactions may result in losses for a Fund which are not
offset by gains on other portfolio positions, thereby reducing gross income.
There also can be no assurance that a liquid secondary market will exist for any
contract purchased or sold, and a Fund may be required to maintain a position
until exercise or expiration, which could result in losses. The SAI contains a
description of the nature and trading mechanics of Options, Options on Stock
Indices, Futures Contracts, Options on Futures Contracts, Forward Contracts and
Options on Foreign Currencies, and includes a discussion of the risks related to
transactions therein.
 
     Transactions in Forward Contracts may be entered into only in the
over-the-counter market. Futures Contracts and Options on Futures Contracts may
be entered into on U.S. exchanges regulated by the Commodity Futures Trading
Commission and on foreign exchanges. In addition, the securities underlying
Options and Futures Contracts traded by a Fund will include U.S. Government
securities as well as foreign securities.
 
                         ------------------------------
 
     The SAI includes a discussion of investment policies and a listing of
specific investment restrictions which govern each Fund's investment policies.
The specific investment restrictions listed in the SAI may be changed without
shareholder approval unless otherwise indicated. See "Investment Policies and
Restrictions" in the SAI.
 
     Each Fund's investment limitations, policies and rating standards are
adhered to at the time of purchase or utilization of assets; a subsequent change
in circumstances will not be considered to result in a violation of policy.

                          7.   MANAGEMENT OF THE FUNDS
- --------------------------------------------------------------------------------
 
   
     INVESTMENT ADVISER -- The Adviser manages each Fund pursuant to separate
Investment Advisory Agreements, each dated September 1, 1995 (the "Advisory
Agreements"). Under each Advisory Agreement the Adviser provides each Fund with
overall investment advisory services. Subject to such policies as the Trustees
may determine, the Adviser makes investment decisions for each Fund. For its
services and facilities, the Adviser receives an annual management fee computed
and paid monthly, in an amount equal to the following annual rates of the
average daily net assets of each Fund:

  Income Fund.............  0.975% of the first $500
                            million and 0.925%
                            thereafter
Emerging Markets Equity
  Fund....................  1.25%
</TABLE>
 
   
     For the fiscal year ended May 31, 1997, MFS received management fees under
the Advisory Agreements of $1,049,705, $277,086 and $687,535 (equivalent on an
annualized basis to 0.975%, 0.975% and 1.25%, respectively, of each Fund's
average daily net assets) for the International Growth Fund, International
Growth and Income Fund and Emerging Markets Equity Fund, respectively.
    
 
   
     These management fees are greater than the fees paid by most funds, but are
comparable to fees paid by funds having similar investment objectives and
policies. MFS also serves as investment adviser to each of the other funds in
the MFS Family of Funds (the "MFS Funds"), and to MFS(R) Municipal Income Trust,
MFS Multimarket Income Trust, MFS Government Markets Income Trust, MFS
Intermediate Income Trust, MFS Charter Income Trust, MFS Special Value Trust,
MFS Union Standard Trust, MFS Institutional Trust, MFS Variable Insurance Trust,
MFS/Sun Life Series Trust, and seven variable accounts, each of which is a
registered investment company established by Sun Life Assurance Company of
Canada (U.S.) ("Sun Life of Canada (U.S.)") in connection with the sale of
various fixed/variable annuity contracts. MFS and its wholly owned subsidiary,
MFS Institutional Advisors, Inc., provide investment advice to substantial
private clients.
    
 
   
     MFS is America's oldest mutual fund organization. MFS and its predecessor
organizations have a history of money management dating from 1924 and the
founding of the first mutual fund in the U.S., Massachusetts Investors Trust.
Net assets under the management of the MFS organization were approximately
$60.39 billion on behalf of approximately 2.6 million investor accounts as of
June 30, 1997. As of such date, the MFS organization managed approximately $36.5
billion of assets in equity securities, approximately $19.6 billion of assets
invested in fixed income funds and fixed income portfolios and approximately
$4.1 billion of assets in foreign securities. MFS is a subsidiary of Sun Life of
Canada (U.S.), which is a subsidiary of Sun Life of Canada (U.S.) Holdings,
Inc., which in turn is a wholly owned subsidiary of Sun Life Assurance Company
of Canada ("Sun Life"). The Directors of MFS are A. Keith Brodkin, Jeffrey L.
Shames, Donald A. Stewart, Arnold D. Scott and John D. McNeil. Mr. Brodkin is
the Chairman, Mr. Shames is the President and Mr. Scott is the Secretary and a
Senior Executive Vice President of MFS. Messrs. McNeil and Stewart are the
Chairman and President, respectively, of Sun Life. Sun Life, a mutual life
insurance company, is one of the largest international life insurance companies
and has been operating in the U.S. since 1895, establishing a headquarters
office here in 1973. The executive officers of MFS report to the Chairman of Sun
Life.
    
 
   
     A. Keith Brodkin, the Chairman of MFS, is also the Chairman and President
of the Trust. W. Thomas London, Stephen E. Cavan, James O. Yost, Ellen M.
Moynihan, Mark E. Bradley and James R. Bordewick, Jr., all of whom are officers
of MFS, are officers of the Trust.
    
 
   
     FCM -- Each Advisory Agreement permits the Adviser from time to time to
engage one or more sub-advisers to assist in the performance of its services.
Pursuant to each Advisory Agreement, the Adviser has engaged Foreign & Colonial
Management Ltd., a company incorporated under the laws of England and Wales
("FCM"), located at Exchange House, Primrose Street, London EC2A 2NY, United
Kingdom, as sub-adviser to render advisory services to the Funds. FCM is a
wholly owned subsidiary of Hypo Foreign & Colonial Management (Holdings) Ltd.
("Hypo F&C"). Sixty-Five percent of the outstanding voting securities of Hypo
F&C is owned by Hypo (U.K.) Holdings Ltd., which is a wholly owned subsidiary of
HYPO-BANK (Bayerische Hypotheken-und Wechsel-Bank AG), the oldest publicly
listed, and fifth largest, commercial bank in Germany, founded in 1835. The
remaining 35% of the outstanding voting securities of Hypo F&C is owned by four
closed-end publicly listed investment Trusts managed by FCM including Foreign &
Colonial Investment Trust PLC. FCM has a history of money management dating from
1868 and the establishment of the world's oldest closed-end fund, Foreign &
Colonial Investment Trust PLC. As of May 31, 1997, FCM managed approximately
U.S. $45.64 billion of assets, including approximately U.S.
    
 
                                       16
<PAGE>   30
 
   
$35.85 billion of assets in equity securities and approximately U.S. $9.79
billion of assets in fixed income securities.
    
 
   
     Under separate Sub-Advisory Agreements between the Adviser and FCM, each
dated September 1, 1995 (the "Sub-Advisory Agreements"), the Adviser may
delegate to FCM the authority to make investment decisions for each Fund. It is
presently intended that FCM will provide portfolio management services for each
of the Funds. For its services, the Adviser pays FCM a management fee, computed
and paid monthly, in an amount equal to 0.80% and 1.00% of the average daily net
assets of the International Growth Fund and the Emerging Markets Equity Fund,
respectively, on an annualized basis and 0.75% of the average daily net assets
managed by FCM of the International Growth and Income Fund on an annualized
basis. The Adviser and FCM have agreed to cooperate in distributing, advising
and managing investment products throughout the world. In this arrangement they
anticipate that certain expenses and revenues relating to their cooperative
activities, including investment advisory fees received from the Funds and
certain expenses incurred by MFS, FCM and their affiliates attributable to their
services to the Funds, will be shared.
    
 
   
     FCEM -- Each Sub-Advisory Agreement permits FCM from time to time to engage
one or more sub-advisers to assist in the performance of its services. Pursuant
to each Sub-Advisory Agreement, FCM has engaged Foreign & Colonial Emerging
Markets Limited, a company incorporated under the laws of England and Wales
("FCEM"), located at Exchange House, Primrose Street, London EC2A 2NY, United
Kingdom, as sub-adviser to render advisory services to the Funds. FCEM is a
wholly owned subsidiary of FCM. FCEM serves as the investment adviser to public
closed-end and open-end funds and segregated accounts specializing in emerging
markets. As of May 31, 1997, FCEM managed approximately U.S. $4.92 billion of
assets invested in emerging markets.
    
 
     Under separate Sub-Advisory Agreements between FCM and FCEM, each dated
September 1, 1995, FCM may delegate to FCEM the authority to make investment
decisions for each Fund. It is presently intended that FCEM will provide
portfolio management services for the portion of the assets of the Funds
invested in emerging markets securities. For its services, FCM pays FCEM a
management fee, computed and paid monthly, in an amount equal to 1.00% of the
average daily net assets managed by FCEM of each Fund on an annualized basis.
 
   
     For the fiscal year ended May 31, 1997, the Adviser paid the Sub-Adviser
fees under the Sub-Advisory Agreements of $857,738, $165,930 and $546,167 in
connection with its services for the International Growth Fund, International
Growth and Income Fund and Emerging Markets Equity Fund, respectively.
    
 
     STRATEGIC ALLIANCE -- The sub-advisory services provided by the Sub-Adviser
to the Funds are part of a strategic alliance between MFS and FCM. As part of
this alliance, the portfolio managers and investment analysts of MFS and FCM
share their views on a variety of investment related issues, such as the
economy, securities markets, portfolio securities and their issuers, investment
recommendations, strategies and techniques, risk analysis, trading strategies
and other portfolio management matters. MFS has access to the extensive
international equity investment expertise of FCM, and FCM has access to the
extensive U.S. equity investment expertise of MFS. MFS and Foreign & Colonial
each have investment personnel working in each other's offices in Boston and
London, respectively.
 
     In certain instances there may be securities which are suitable for a
Fund's portfolio as well as for portfolios of other clients of MFS or clients of
FCM. Some simultaneous transactions are inevitable when several clients receive
investment advice from MFS and FCM, particularly when the same security is
suitable for more than one client. While in some cases this arrangement could
have a detrimental effect on the price or availability of the security as far as
a Fund is concerned, in other cases it may produce increased investment
opportunities for the Fund.
 
     PORTFOLIO MANAGERS -- The identity and background of the portfolio managers
for each Fund is set forth below. Each of the following portfolio managers has
acted in that capacity since the commencement of investment operations of each
Fund unless otherwise noted:
 
   
     International Growth Fund -- Ian K. Wright, a director of FCM, and June
     Scott, a Global Funds Manager of FCM, are the Fund's portfolio managers.
     Mr. Wright has been employed as a portfolio manager by FCM since 1981 and
     has been one of the Fund's portfolio managers since March, 1996. Mr. Wright
     is currently head of Japanese equities at FCM. Ms. Scott has been employed
     by FCM since 1995, before which she completed her MBA at the London
     Business School. Prior to completing her MBA, Ms. Scott worked as a
     Quantitative Portfolio Analyst in the Equity Research Group at J.P. Morgan
     Investment Management in London. Ms. Scott has been one of the Fund's
     portfolio managers since March, 1996.

                8.   INFORMATION CONCERNING SHARES OF THE FUNDS
- --------------------------------------------------------------------------------
 
PURCHASES
 
   
     Shares of the Funds may be purchased at the public offering price through
any dealer. As used in the Prospectus and any appendices thereto the term
"dealer" includes any broker, dealer, bank (including bank trust departments),
registered investment adviser, financial planner and any other financial
institutions having a selling agreement or other similar agreement with MFD.
Dealers may also charge their customers fees relating to investments in the
Funds.
    
 
   
     This prospectus offers three classes of shares to the general public (Class
A, Class B and Class C shares) which bear sales charges and distribution fees in
different forms and amounts, as described below:
    
 
     CLASS A SHARES: Class A shares are generally offered at net asset value
plus an initial sales charge, but in certain cases are offered at net asset
value without an initial sales charge but subject to a CDSC.
 
     PURCHASES SUBJECT TO INITIAL SALES CHARGE. Class A shares of each Fund are
offered at net asset value plus an initial sales charge as follows:

</TABLE>
 
- ---------------
 * Because of rounding in the calculation of offering price, actual sales
   charges may be more or less than those calculated using the percentages above
   (see the SAI).
** A CDSC will apply to such purchases, as discussed below.
 
     MFD allows discounts to dealers (which are alike for all dealers) from the
applicable public offering price, as shown in the above table. In the case of
the maximum sales charge, the dealer retains 4% and MFD retains approximately
 3/4 of 1% of the public offering price. The sales charge may vary depending on
the number of shares of a Fund as well as certain other MFS Funds owned or being
purchased, the existence of an agreement to purchase additional shares during a
13-month period (or 36-month period for purchases of $1 million or more) or
other special purchase programs. A description of the Right of Accumulation,
Letter of Intent and Group Purchase privileges by which the sales charge may be
reduced is set forth in the SAI.
 
   
     PURCHASES SUBJECT TO A CDSC (but not an initial sales charge). In the
following five circumstances, Class A shares of each Fund are also offered at
net asset value without an initial sales charge but subject to a CDSC, equal to
1% of the lesser of the value of the shares redeemed (exclusive of reinvested
dividend and capital gain distributions) or the total cost of such shares, in
the event of a share redemption within 12 months following the purchase:
    
 
      (i) on investments of $1 million or more in Class A shares;
 
   
     (ii) on investments in Class A shares by certain retirement plans subject
          to the Employee Retirement Income Security Act of 1974, as amended
          ("ERISA"), if prior to July 1, 1996: (a) the plan had established an
          account with the Shareholder Servicing Agent and (b) the sponsoring
          organization had demonstrated to the satisfaction of MFD that either
          (i) the employer had at least 25 employees or (ii) the aggregate
          purchases by the retirement plan of Class A shares of the Funds in the
          MFS Funds would be in an aggregate amount of at least $250,000 within
          a reasonable period of time, as determined by MFD in its sole
          discretion;
    
 
                                       18
<PAGE>   32
 
   
    (iii)  on investments in Class A shares by certain retirement plans subject
           to ERISA, if: (a) the retirement plan and/or sponsoring organization
           subscribes to the MFS FUNDamental 401(k) Program or any similar
           recordkeeping system made available by the Shareholder Servicing
           Agent (the "MFS Participant Recordkeeping System"); (b) the plan
           establishes an account with the Shareholder Servicing Agent on or
           after July 1, 1996; and (c) the aggregate purchases by the retirement
           plan of Class A shares of the MFS Funds will be in an aggregate
           amount of at least $500,000 within a reasonable period of time, as
           determined by MFD in its sole discretion;
    
 
   
     (iv)  on investments in Class A shares by certain retirement plans
           subject to ERISA, if: (a) the plan establishes an account with the
           Shareholder Servicing Agent on or after July 1, 1996 and (b) the
           plan has, at the time of purchase, a market value of $500,000 or
           more invested in shares of any class or classes of the MFS Funds.
           THE RETIREMENT PLAN WILL QUALIFY UNDER THIS CATEGORY ONLY IF THE
           PLAN OR ITS SPONSORING ORGANIZATION INFORMS THE SHAREHOLDER
           SERVICING AGENT PRIOR TO THE PURCHASE THAT THE PLAN HAS A MARKET
           VALUE OF $500,000 OR MORE INVESTED IN SHARES OF ANY CLASS OR CLASSES
           OF THE MFS FUNDS. THE SHAREHOLDER SERVICING AGENT HAS NO OBLIGATION
           INDEPENDENTLY TO DETERMINE WHETHER SUCH A PLAN QUALIFIES UNDER
           THIS CATEGORY; AND
     
   
      (v)  on investments in Class A shares by certain retirement plans
           subject to ERISA if: (a) the plan establishes an account with the
           Shareholder Servicing Agent on or after July 1, 1997; (b) such
           plan's records are maintained on a pooled basis by the Shareholder
           Servicing Agent; and (c) the sponsoring organization demonstrates to
           the satisfaction of MFD that, at the time of purchase, the employer
           has at least 200 eligible employees and the plan has aggregate
           assets of at least $2,000,000.
    
 
     In the case of such purchases, MFD will pay commissions to dealers on new
investments in Class A shares made through such dealers, as follows:
 
<TABLE>
<CAPTION>
COMMISSION PAID
    BY MFD
  TO DEALERS     CUMULATIVE PURCHASE AMOUNT
- ---------------  --------------------------
<S>              <C>
1.00%..........  On the first $2,000,000, plus
0.80%..........  Over $2,000,000 to $3,000,000, plus
0.50%..........  Over $3,000,000 to $50,000,000, plus
0.25%..........  Over $50,000,000
</TABLE>
 
     For purposes of determining the level of commissions to be paid to dealers
with respect to a shareholder's new investment in Class A shares made on or
after April 1, 1996, purchases for each shareholder account (and certain other
accounts for which the shareholder is a record or beneficial holder) will be
aggregated over a 12-month period (commencing from the date of the first such
purchase).
 
     See "Redemptions and Repurchases -- Contingent Deferred Sales Charge" for
further discussion of the CDSC.
 
     WAIVERS OF INITIAL SALES CHARGE AND CDSC. In certain circumstances, the
initial sales charge imposed upon purchases of Class A shares and the CDSC
imposed upon redemptions of Class A shares is waived. These circumstances are
described in Appendix A to this Prospectus. In addition to these circumstances,
the CDSC imposed upon the redemption of Class A shares is waived with respect to
shares held by certain retirement plans qualified under Section 401(a) or 403(b)
of the Internal Revenue Code of 1986, as amended (the "Code"), and subject to
ERISA, where:
 
     (i) the retirement plan and/or sponsoring organization does not subscribe
         to the MFS Participant Recordkeeping System; and
 
    (ii) the retirement plan and/or sponsoring organization demonstrates to the
         satisfaction of, and certifies to the Shareholder Servicing Agent that
         the retirement plan has, at the time of certification or will have
         pursuant to a purchase order placed with the certification, a market
         value of $500,000 or more invested in shares of any class or classes
         of the MFS Funds and aggregate assets of at least $10  million;
        
provided, however, that the CDSC will not be waived (i.e., it will be imposed)
in the event that there is a change in law or regulations which results in a
material adverse change to the tax advantaged nature of the plan, or in the
event that the plan and/or sponsoring organization: (i) becomes insolvent or
bankrupt; (ii) is terminated or partially terminated under ERISA or is
liquidated or dissolved; or (iii) is acquired by, merged into, or consolidated
with any other entity.
 
     CLASS B SHARES:  Class B shares of each Fund are offered at net asset value
without an initial sales charge but subject to a CDSC upon redemption as
follows:

</TABLE>
 
                                       19
<PAGE>   33
 
     The CDSC imposed is assessed against the lesser of the value of the shares
redeemed (exclusive of reinvested dividends and capital gain distributions) or
the total cost of such shares. No CDSC is assessed against shares acquired
through the automatic reinvestment of dividends or capital gain distributions.
 
   
     Except as described below, MFD will pay commissions to dealers of 3.75% of
the purchase price of Class B shares purchased through dealers. MFD will also
advance to dealers the first year service fee payable under each Fund's
Distribution Plan (see "Distribution Plan" below) at a rate equal to 0.25% of
the purchase price of such shares. Therefore, the total amount paid to a dealer
upon the sale of Class B shares is 4% of the purchase price of the shares
(commission rate of 3.75% plus a service fee equal to 0.25% of the purchase
price).
    
 
   
     Class B shares purchased by a retirement plan whose sponsoring organization
subscribes to the MFS Participant Recordkeeping System and which has established
its account with the Shareholder Servicing Agent on or after July 1, 1996, will
be subject to the CDSC described above, only under limited circumstances, as
explained below under "Waivers of CDSC." With respect to such purchases, MFD
pays an amount to dealers equal to 3.00% of the amount purchased through such
dealers (rather than the 4.00% payment described above), which is comprised of a
commission of 2.75% plus the advancement of the first year service fee equal to
0.25% of the purchase price payable under each Fund's Distribution Plan. As
discussed above, such retirement plans are eligible to purchase Class A shares
of the Funds at net asset value without an initial sales charge but subject to a
1% CDSC if the plan has, at the time of purchase, a market value of $500,000 or
more invested in shares of any class or classes of the MFS Funds. IN THIS EVENT,
THE PLAN OR ITS SPONSORING ORGANIZATION SHOULD INFORM THE SHAREHOLDER SERVICING
AGENT THAT THE PLAN IS ELIGIBLE TO PURCHASE CLASS A SHARES UNDER THIS CATEGORY;
THE SHAREHOLDER SERVICING AGENT HAS NO OBLIGATION INDEPENDENTLY TO DETERMINE
WHETHER SUCH A PLAN QUALIFIES UNDER THIS CATEGORY FOR THE PURCHASE OF CLASS A
SHARES.
    
 
     See "Redemptions and Repurchases -- Contingent Deferred Sales Charge" for
further discussion of the CDSC.
 
     WAIVERS OF CDSC.  In certain circumstances, the CDSC imposed upon
redemption of Class B shares is waived. These circumstances are described in
Appendix A to this Prospectus. In addition to these circumstances, the CDSC
imposed upon the redemption of Class B shares is waived with respect to shares
held by a retirement plan whose sponsoring organization subscribes to the MFS
Participant Recordkeeping System and which has established an account with the
Shareholder Servicing Agent on or after July 1, 1996; provided, however, that
the CDSC will not be waived (i.e., it will be imposed) in the event that there
is a change in law or regulations which results in a material adverse change to
the tax advantaged nature of the plan, or in the event that the plan and/or
sponsoring organization: (i) becomes insolvent or bankrupt; (ii) is terminated
or partially terminated under ERISA or is liquidated or dissolved; or (iii) is
acquired by, merged into, or consolidated with any other entity.
 
   
     CONVERSION OF CLASS B SHARES.  Class B shares of each Fund that remain
outstanding for approximately eight years will convert to Class A shares of the
same Fund. Shares purchased through the reinvestment of distributions paid in
respect of Class B shares will be treated as Class B shares for purposes of the
payment of the distribution and service fees under each Fund's Distribution
Plan. See "Distribution Plan" below. However, for purposes of conversion to
Class A shares, all shares in a shareholder's account that were purchased
through the reinvestment of dividends and distributions paid in respect of Class
B shares (and which have not converted to Class A shares as provided in the
following sentence) will be held in a separate sub-account. Each time any Class
B shares in the shareholder's account (other than those in the sub-account)
convert to Class A shares, a portion of the Class B shares then in the
sub-account will also convert to Class A shares. The portion will be determined
by the ratio that the shareholder's Class B shares not acquired through
reinvestment of dividends and distributions that are converting to Class A
shares bear to the shareholder's total Class B shares not acquired through
reinvestment. The conversion of Class B shares to Class A shares is subject to
the continuing availability of a ruling from the Internal Revenue Service or an
opinion of counsel that such conversion will not constitute a taxable event for
federal tax purposes. There can be no assurance that such ruling or opinion will
be available, and the conversion of Class B shares to Class A shares will not
occur if such ruling or opinion is not available. In such event, Class B shares
would continue to be subject to higher expenses than Class A shares for an
indefinite period.
    
 
     CLASS C SHARES:  Class C shares are offered at net asset value without an
initial sales charge but are subject to a CDSC upon redemption of 1.00% during
the first year. Class C shares do not convert to any other class of shares of
the Fund. The maximum investment in Class C shares that may be made is up to
$1,000,000 per transaction.
 
     The CDSC imposed is assessed against the lesser of the value of the shares
redeemed (exclusive of reinvested dividend and capital gain distributions) or
the total cost of such shares. No CDSC is assessed against shares acquired
through the automatic reinvestment of dividend or capital gain distributions.
See "Redemptions and Repurchases -- Contingent Deferred Sales Charge" below for
further discussion of the CDSC.
 
                                       20
<PAGE>   34
 
     MFD will pay dealers 1.00% of the purchase price of Class C shares
purchased through dealers and, as compensation therefor, MFD will retain the
1.00% per annum distribution and service fee paid under the Class C Distribution
Plan by the Fund to MFD for the first year after purchase (see "Distribution
Plans" below).
 
     Class C shares are not currently available for purchase by any retirement
plan qualified under Sections 401(a) or 403(b) of the Internal Revenue Code of
1986, as amended (the "Code"), if the retirement plan and/or the sponsoring
organization subscribe to the MFS FUNDamental 401(k) Plan or another similar
recordkeeping program made available by the Shareholder Servicing Agent.
 
     WAIVERS OF CDSC.  In certain circumstances, the CDSC imposed upon
redemption of Class C shares is waived. These circumstances are described in
Appendix A to this Prospectus.
 
     GENERAL:  The following information applies to purchases of each class of
each Fund's shares.
 
     MINIMUM INVESTMENT.  Except as described below, the minimum initial
investment is $1,000 per account and the minimum additional investment is $50
per account. Accounts being established for monthly automatic investments and
under payroll savings programs and tax-deferred retirement programs (other than
IRAs) involving the submission of investments by means of group remittal
statements are subject to a $50 minimum on initial and additional investments
per account. The minimum initial investment for IRAs is $250 per account and the
minimum additional investment is $50 per account. Accounts being established for
participation in the Automatic Exchange Plan are subject to a $50 minimum on
initial and additional investments per account. There are also other limited
exceptions to these minimums for certain tax-deferred retirement programs. Any
minimums may be changed at any time at the discretion of MFD. Each Fund reserves
the right to cease offering its shares at any time.
 
   
     SUBSEQUENT INVESTMENT BY TELEPHONE:  Each shareholder may purchase
additional shares of any MFS Fund by telephoning the Shareholder Servicing Agent
toll-free at (800) 225-2606. The minimum purchase amount is $50 and the maximum
purchase amount is $100,000. Shareholders wishing to avail themselves of this
telephone purchase privilege must so elect on their Account Application and
designate thereon a bank and account number from which purchases will be made.
If a telephone purchase request is received by the Shareholder Servicing Agent
on any business day prior to the close of regular trading on the Exchange
(generally, 4:00 p.m., Eastern time), the purchase will occur at the closing net
asset value of the shares purchased on that day. The Shareholder Servicing Agent
may be liable for any losses resulting from unauthorized telephone transactions
if it does not follow reasonable procedures designed to verify the identity of
the caller. The Shareholder Servicing Agent will request personal or other
information from the caller, and will normally also record calls. Shareholders
should verify the accuracy of confirmation statements immediately after their
receipt.
    
 
   
     RIGHT TO REJECT PURCHASE ORDERS/MARKET TIMING.  Purchases and exchanges
should be made for investment purposes only. The Fund and MFD each reserves the
right to reject or restrict any specific purchase or exchange request. In the
event that the Fund or MFD rejects an exchange request, neither the redemption
nor the purchase side of the exchange will be processed.
    
 
   
     The Fund is not designed for professional market timing organizations or
other entities using programmed or frequent exchanges. The Fund defines a
"market timer" as an individual, or organization acting on behalf of one or more
individuals, if (i) the individual or organization makes three or more exchange
requests out of the Fund per calendar year and (ii) any one of such exchange
requests represents shares equal in value to 1/2 of 1% or more of the Fund's net
assets at the time of the request. Accounts under common ownership or control,
including accounts administered by market timers, will be aggregated for
purposes of this definition.
    
 
   
     As noted above, the Fund and MFD each reserves the right to reject or
restrict any specific purchase and exchange request, and, in addition may impose
specific limitations with respect to market timers, including delaying for up to
seven days the purchase side of an exchange request by market timers or
specifically rejecting or otherwise restricting purchase or exchange requests by
market timers. In the event that any individual or entity is determined either
by the Fund or MFD, in its sole discretion, to be a market timer with respect to
any calendar year, the Fund and/or MFD will reject all exchange requests into
the Fund during the remainder of that calendar year. Other funds in the MFS
Family of Funds may have different and/or more restrictive policies with respect
to market timers than the Fund. These policies are disclosed in the prospectuses
of these other MFS Funds.
    
 
   
     DEALER CONCESSIONS.  Dealers may receive different compensation with
respect to sales of Class A and Class B shares. In addition, from time to time,
MFD may pay dealers 100% of the applicable sales charge on sales of Class A
shares of certain specified MFS Funds sold by such dealer during a specified
sales period. In addition, MFD or its affiliates may, from time to time, pay
dealers an additional commission equal to 0.50% of the net asset value of all of
the Class B and/or Class C shares of certain specified MFS Funds sold by such
dealer during a specified sales period. In addition, from time to time, MFD, at
its expense, may provide additional commissions, compensation or promotional
incentives ("concessions") to dealers which sell shares of a Fund. Such
concessions provided by MFD may include financial assistance to
    
 
                                       21
<PAGE>   35
 
dealers in connection with preapproved conferences or seminars, sales or
training programs for invited registered representatives, payment for travel
expenses, including lodging, incurred by registered representatives for such
seminars or training programs, seminars for the public, advertising and sales
campaigns regarding one or more MFS Funds, and/or other dealer-sponsored
events. From time to time, MFD may make expense reimbursements for special
training of a dealer's registered representatives in group meetings or to help
pay the expenses of sales contests. Other concessions may be offered to the
extent not prohibited by state laws or any self-regulatory agency, such as the
NASD.
 
     SPECIAL INVESTMENT PROGRAMS.  For shareholders who elect to participate in
certain investment programs (e.g., the Automatic Investment Plan) or other
shareholder services, MFD or its affiliates may either (i) give a gift of
nominal value, such as a hand-held calculator, or (ii) make a nominal charitable
contribution on their behalf.
 
   
     RESTRICTIONS ON ACTIVITIES OF NATIONAL BANKS.  The Glass-Steagall Act
prohibits national banks from engaging in the business of underwriting, selling
or distributing securities. Although the scope of the prohibition has not been
clearly defined, MFD believes that such Act should not preclude banks from
entering into agency agreements with MFD. If, however, a bank were prohibited
from so acting, the Trustees would consider what actions, if any, would be
necessary to continue to provide efficient and effective shareholder services in
respect of shareholders who invested in a Fund through a national bank. It is
not expected that shareholders would suffer any adverse financial consequence as
a result of these occurrences. In addition, state securities laws on this issue
may differ from the interpretation of federal law expressed herein and banks and
financial institutions may be required to register as broker-dealers pursuant to
state law.
    
 
                         ------------------------------
 
     A shareholder whose shares are held in the name of, or controlled by, a
dealer might not receive many of the privileges and services from a Fund (such
as Right of Accumulation, Letter of Intent and certain recordkeeping services)
that the Fund ordinarily provides.
 
EXCHANGES
     Subject to the requirements set forth below, some or all of the shares in
an account with a Fund for which payment has been received by the Fund (i.e., an
established account) may be exchanged for shares of the same class of any of the
other MFS Funds at net asset value (if available for sale). Shares of one class
may not be exchanged for shares of any other class.
 
     EXCHANGES AMONG MFS FUNDS (EXCLUDING EXCHANGES FROM MFS MONEY MARKET
FUNDS):  No initial sales charges or CDSC will be imposed in connection with an
exchange from shares of an MFS Fund to shares of any other MFS Fund, except with
respect to exchanges from an MFS money market fund to another MFS Fund which is
not an MFS money market fund (discussed below). With respect to an exchange
involving shares subject to a CDSC, the CDSC will be unaffected by the exchange
and the holding period for purposes of calculating the CDSC will carry over to
the acquired shares.
 
     EXCHANGES FROM AN MFS MONEY MARKET FUND:  Special rules apply with respect
to the imposition of an initial sales charge or a CDSC for exchanges from an MFS
money market fund to another MFS Fund which is not an MFS money market fund.
These rules are described under the caption "Exchanges" in the Prospectuses of
those MFS money market funds.
 
     EXCHANGES INVOLVING THE MFS FIXED FUND:  Class A shares of any MFS Fund
held by certain qualified retirement plans may be exchanged for units of
participation of the MFS Fixed Fund (a bank collective investment fund) (the
"Units"), and Units may be exchanged for Class A shares of any MFS Fund. With
respect to exchanges between Class A shares subject to a CDSC and Units, the
CDSC will carry over to the acquired shares or Units and will be deducted from
the redemption proceeds when such shares or Units are subsequently redeemed,
assuming the CDSC is then payable (the period during which the Class A shares
and the Units were held will be aggregated for purposes of calculating the
applicable CDSC). In the event that a shareholder initially purchases Units and
then exchanges into Class A shares subject to an initial sales charge of an MFS
Fund, the initial sales charge shall be due upon such exchange, but will not be
imposed with respect to any subsequent exchanges between such Class A shares and
Units with respect to shares on which the initial sales charge has already been
paid. In the event that a shareholder initially purchases Units and then
exchanges into Class A shares subject to a CDSC of an MFS Fund, the CDSC period
will commence upon such exchange, and the applicability of the CDSC with respect
to subsequent exchanges shall be governed by the rules set forth in this
paragraph above.
 
     GENERAL:  A shareholder should read the prospectus of the other MFS Fund
and consider the differences in objectives, policies and restrictions before
making any exchange. Exchanges will be made only after instructions in writing
or by telephone (an "Exchange Request") are received for an established account
by the Shareholder Servicing Agent in proper form (i.e., if in writing -- signed
by the record owner(s) exactly as the shares are registered; if by
telephone -- proper account identification is given by the dealer or shareholder
of record) and each exchange must involve either shares having an aggregate
value of at least $1,000 ($50 in the case of retirement plan participants whose
sponsoring organizations subscribe to the MFS FUNDamental 401(k) Plan or another
similar 401(k) recordkeeping system made available by the Shareholder Servicing
Agent) or all the shares
 
                                       22
<PAGE>   36
 
   
in the account. If an Exchange Request is received by the Shareholder Servicing
Agent on any business day prior to the close of regular trading on the New York
Stock Exchange (generally, 4:00 p.m., Eastern time) (the "Exchange"), the
exchange will occur on that day if all the requirements set forth above have
been complied with at that time and subject to the Fund's right to reject
purchase orders. No more than five exchanges may be made in any one Exchange
Request by telephone. Additional information concerning this exchange privilege
and prospectuses for any of the other MFS Funds may be obtained from dealers or
the Shareholder Servicing Agent. For federal and (generally) state income tax
purposes, an exchange is treated as a sale of the shares exchanged and,
therefore, an exchange could result in a gain or loss to the shareholder making
the exchange. Exchanges by telephone are automatically available to most
non-retirement plan accounts and certain retirement plan accounts. For further
information regarding exchanges by telephone, see "Redemptions by Telephone."
The exchange privilege (or any aspect of it) may be changed or discontinued and
is subject to certain limitations, including certain restrictions on purchases
by market timers.
    
 
   
REDEMPTIONS AND REPURCHASES
    
     A shareholder may withdraw all or any portion of the value of his account
on any date on which a Fund is open for business by redeeming shares at their
net asset value (a redemption) or by selling such shares to the Fund through a
dealer (a repurchase). Certain redemptions and repurchases are, however, subject
to a CDSC. See "Contingent Deferred Sales Charge" below. Because the net asset
value of shares of the account fluctuates, redemptions or repurchases, which are
taxable transactions, are likely to result in gains or losses to the
shareholder. When a shareholder withdraws an amount from his account, the
shareholder is deemed to have tendered for redemption a sufficient number of
full and fractional shares in his account to cover the amount withdrawn. The
proceeds of a redemption or repurchase will normally be available within seven
days, except for shares purchased or received in exchange for shares purchased
by check (including certified checks or cashier's checks). Payment of redemption
proceeds may be delayed for up to 15 days from the purchase date in an effort to
assure that such check has cleared. See "Tax Status" below.
 
     REDEMPTION BY MAIL:  Each shareholder may redeem all or any portion of the
shares in his account by mailing or delivering to the Shareholder Servicing
Agent (see back cover for address) a stock power with a written request for
redemption or letter of instruction, together with his share certificates (if
any were issued), all in "good order" for transfer. "Good order" generally means
that the stock power, written request for redemption, letter of instruction or
certificate must be endorsed by the record owner(s) exactly as the shares are
registered and the signature(s) must be guaranteed in the manner set forth below
under the caption "Signature Guarantee." In addition, in some cases "good order"
will require the furnishing of additional documents. The Shareholder Servicing
Agent may make certain de minimis exceptions to the above requirements for
redemption. Within seven days after receipt of a redemption request in "good
order" by the Shareholder Servicing Agent, a Fund will make payment in cash of
the net asset value of the shares next determined after such redemption request
was received, reduced by the amount of any applicable CDSC described above and
the amount of any income tax required to be withheld, except during any period
in which the right of redemption is suspended or date of payment is postponed
because the Exchange is closed or trading on such Exchange is restricted or to
the extent otherwise permitted by the 1940 Act if an emergency exists.
 
     REDEMPTION BY TELEPHONE:  Each shareholder may redeem an amount from his
account by telephoning the Shareholder Servicing Agent toll-free at (800)
225-2606. Shareholders wishing to avail themselves of this telephone redemption
privilege must so elect on their Account Application, designate thereon a bank
and account number to receive the proceeds of such redemption, and sign the
Account Application Form with the signature(s) guaranteed in the manner set
forth below under the caption "Signature Guarantee." The proceeds of such a
redemption, reduced by the amount of any applicable CDSC and the amount of any
income tax required to be withheld, are mailed by check to the designated
account, without charge, if the redemption proceeds do not exceed $1,000, and
are wired in federal funds to the designated account if the redemption proceeds
exceed $1,000. If a telephone redemption request is received by the Shareholder
Servicing Agent by the close of regular trading on the Exchange on any business
day, shares will be redeemed at the closing net asset value of the Fund on that
day. Subject to the conditions described in this section, proceeds of a
redemption are normally mailed or wired on the next business day following the
date of receipt of the order for redemption. The Shareholder Servicing Agent may
be responsible for any losses resulting from unauthorized telephone transactions
if it does not follow reasonable procedures designed to verify the identity of
the caller. The Shareholder Servicing Agent will request personal or other
information from the caller, and will normally also record calls. Shareholders
should verify the accuracy of confirmation statements immediately after their
receipt.
 
     REPURCHASE THROUGH A DEALER:  If a shareholder desires to sell his shares
through his dealer (a repurchase), the shareholder can place a repurchase order
with his dealer, who may charge the shareholder a fee. IF THE DEALER RECEIVES
THE SHAREHOLDER'S ORDER PRIOR TO THE CLOSE OF REGULAR TRADING ON THE EXCHANGE
AND COMMUNICATES IT TO MFD BEFORE THE CLOSE OF BUSINESS ON THE SAME DAY, THE
SHAREHOLDER WILL RECEIVE THE NET ASSET VALUE CALCULATED ON THAT DAY, REDUCED BY
THE
 
                                       23
<PAGE>   37
 
AMOUNT OF ANY APPLICABLE CDSC AND THE AMOUNT OF ANY INCOME TAX REQUIRED TO BE
WITHHELD.
 
   
     CONTINGENT DEFERRED SALES CHARGE:  Investments in Class A, Class B or Class
C shares ("Direct Purchases") will be subject to a CDSC for a period of (i) with
respect to Class A and Class C shares, 12 months (however, the CDSC on Class A
shares is only imposed with respect to purchases of $1 million or more of Class
A shares or purchases by certain retirement plans of Class A shares) or (ii)
with respect to Class B shares, six years. Purchases of Class A shares made
during a calendar month, regardless of when during the month the investment
occurred, will age one month on the last day of the month and each subsequent
month. Class C shares and Class B shares of any MFS Fund purchased on or after
January 1, 1993 will be aggregated on a calendar month basis -- all transactions
made during a calendar month, regardless of when during the month they have
occurred, will age one year at the close of business on the last day of such
month in the following calendar year and each subsequent year. For Class B
shares of any MFS Fund purchased prior to January 1, 1993, transactions will be
aggregated on a calendar year basis -- all transactions made during a calendar
year, regardless of when during the year they have occurred, will age one year
at the close of business on December 31 of that year and each subsequent year.
    
 
   
     At the time of a redemption, the amount by which the value of a
shareholder's account for a particular class of shares represented by Direct
Purchases exceeds the sum of the six calendar year aggregations (12 months in
the case of purchases of Class C shares and of purchases of $1 million or more
of Class A shares or purchases by certain retirement plans of Class A shares) of
Direct Purchases may be redeemed without charge ("Free Amount"). Moreover, no
CDSC is ever assessed on additional shares acquired through the automatic
reinvestment of dividends or capital gain distributions ("Reinvested Shares").
Therefore, at the time of redemption of a particular class, (i) any Free Amount
is not subject to the CDSC and (ii) the amount of the redemption equal to the
then-current value of Reinvested Shares is not subject to the CDSC, but (iii)
any amount of the redemption in excess of the aggregate of the then-current
value of Reinvested Shares and the Free Amount is subject to a CDSC. The CDSC
will first be applied against the amount of Direct Purchases which will result
in any such charge being imposed at the lowest possible rate. The CDSC to be
imposed upon redemptions of shares will be calculated as set forth in
"Purchases" above.
    
 
   
     The applicability of a CDSC will be unaffected by exchanges or transfers of
registration, except as described in Appendix A hereto.
    
 
     GENERAL:  The following information applies to redemptions and repurchases
of each class of each Fund's shares.
 
     SIGNATURE GUARANTEE.  In order to protect shareholders against fraud, each
Fund requires, in certain instances as indicated above, that the shareholder's
signature be guaranteed. In these cases the shareholder's signature must be
guaranteed by an eligible bank, broker, dealer, credit union, national
securities exchange, registered securities association, clearing agency or
savings association. Signature guarantees shall be accepted in accordance with
policies established by the Shareholder Servicing Agent.
 
     REINSTATEMENT PRIVILEGE.  Shareholders of each Fund who have redeemed their
shares have a one-time right to reinvest the redemption proceeds in the same
class of shares of any of the MFS Funds (if shares of such Fund are available
for sale) at net asset value (with a credit for any CDSC paid) within 90 days of
the redemption pursuant to the Reinstatement Privilege. If the shares credited
for any CDSC paid are then redeemed within six years of the initial purchase in
the case of Class B shares or within 12 months of the initial purchase for Class
C shares and certain Class A share purchases, a CDSC will be imposed upon
redemption. Such purchases under the Reinstatement Privilege are subject to all
limitations in the SAI regarding this privilege.
 
     IN-KIND DISTRIBUTIONS.  The Trust agrees to redeem shares of each Fund
solely in cash up to the lesser of $250,000 or 1% of the net asset value of the
Fund during any 90-day period for any one shareholder. Each Fund has reserved
the right to pay other redemptions either totally or partially, by a
distribution in-kind of securities (instead of cash) from the Fund's portfolio.
The securities distributed in such a distribution would be valued at the same
amount as that assigned to them in calculating the net asset value for the
shares being sold. If a shareholder received a distribution in-kind, the
shareholder could incur brokerage or transaction charges when converting the
securities to cash. Any distribution in-kind of portfolio securities may include
foreign securities, including securities of issuers in emerging markets. Such
securities may be subject to risks not typically associated with the risks of
U.S. securities. See "Risk Factors -- Foreign Securities" and " -- Emerging
Markets."
 
   
     INVOLUNTARY REDEMPTIONS/SMALL ACCOUNTS.  Due to the relatively high cost of
maintaining small accounts, each Fund reserves the right to redeem shares in any
account for their then-current value if at any time the total investment in such
account drops below $500 because of redemptions or exchanges, except in the case
of accounts being established for monthly automatic investments and certain
payroll savings programs, Automatic Exchange Plan accounts and tax-deferred
retirement plans, for which there is a lower minimum investment requirement. See
"Purchases -- General -- Minimum Investment." Shareholders will be notified that
the value of their account is less than the minimum investment requirement and
allowed 60 days to make an additional investment before the redemption is
processed.

DISTRIBUTION PLAN
     The Trustees have adopted a Distribution Plan for Class A, Class B and
Class C shares of each Fund pursuant to Section 12(b) of the 1940 Act and Rule
12b-1 thereunder (the "Distribution Plan"), after having concluded that there is
a reasonable likelihood that the Distribution Plan would benefit the Fund and
its shareholders.
    
 
     In certain circumstances, the fees described below may not be imposed or
are being waived. These circumstances, if any, are described below under the
heading "Current Level of Distribution and Service Fees."
 
   
     FEATURES COMMON TO EACH CLASS OF SHARES:  There are certain features of the
Distribution Plan that are common to each class of Shares, as described below.
 
     SERVICE FEES.  The Distribution Plan provides that the Fund may pay MFD a
service fee of up to 0.25% of the average daily net assets attributable to the
class of shares to which the Distribution Plan relates (i.e., Class A, Class B
or Class C shares, as appropriate) (the "Designated Class") annually in order
that MFD may pay expenses on behalf of the Fund relating to the servicing of
shares of the Designated Class. The service fee is used by MFD to compensate
dealers which enter into a sales agreement with MFD in consideration for all
personal services and/or account maintenance services rendered by the dealer
with respect to shares of the Designated Class owned by investors for whom such
dealer is the dealer or holder of record. MFD may from time to time reduce the
amount of the service fees paid for shares sold prior to a certain date. Service
fees may be reduced for a dealer that is the holder or dealer of record for an
investor who owns shares of the Fund having an aggregate net asset value at or
above a certain dollar level. Dealers may from time to time be required to meet
certain criteria in order to receive service fees. MFD or its affiliates are
entitled to retain all service fees payable under the Distribution Plan for
which there is no dealer of record or for which qualification standards have not
been met as partial consideration for personal services and/or account
maintenance services performed by MFD or its affiliates to shareholder accounts.
 
     DISTRIBUTION FEES.  The Distribution Plan provides that the Fund may pay
MFD a distribution fee based on the average daily net assets attributable to the
Designated Class as partial consideration for distribution services performed
and expenses incurred in the performance of MFD's obligations under its
distribution agreement with the Fund. See "Management of the
Fund -- Distributor" in the SAI. The amount of the distribution fee paid by the
Fund with respect to each class differs under the Distribution Plan, as does the
use by MFD of such distribution fees. Such amounts and uses are described below
in the discussion of the provisions of the Distribution Plan relating to each
class of shares. While the amount of compensation received by MFD in the form of
distribution fees during any year may be more or less than the expenses incurred
by MFD under its distribution agreement with the Funds, the Funds are not liable
to MFD for any losses MFD may incur in performing services under its
distribution agreement with the Funds.
 
     OTHER COMMON FEATURES.  Fees payable under the Distribution Plan are
charged to, and therefore reduce, income allocated to shares of the Designated
Class. The provisions of the Distribution Plan relating to operating policies as
well as initial approval, renewal, amendment and termination are substantially
identical as they relate to each class of Shares covered by the Distribution
Plan.
 
     FEATURES UNIQUE TO EACH CLASS OF SHARES:  There are certain features of the
Distribution Plan that are unique to each class of shares, as described below.
 
     CLASS A SHARES.  Class A shares of each Fund are generally offered pursuant
to an initial sales charge, a substantial portion of which is paid to or
retained by the dealer making the sale (the remainder of which is paid to MFD).
See "Purchases -- Class A Shares" above. In addition to the initial sales
charge, the dealer also generally receives the ongoing 0.25% per annum service
fee, as discussed above.
 
     The distribution fee paid to MFD under the Distribution Plan is equal, on
an annual basis, to 0.25% of the Fund's average daily net assets attributable to
Class A shares. As noted above, MFD may use the distribution fee to cover
distribution-related expenses incurred by it under its distribution agreement
with a Fund (e.g., MFD pays commissions to dealers with respect to purchases of
$1 million or more and purchases by certain retirement plans of Class A shares
which are sold at net asset value but which are subject to a 1% CDSC for one
year after purchase). Distribution fee payments under the Class A Distribution
Plans may be used by MFD to pay securities dealers a distribution fee in an
amount equal on an annual basis to 0.25% per annum of each Fund's average daily
net assets attributable to Class A shares (other than Class A shares that have
converted from Class B shares) owned by investors for whom that securities
dealer is the holder or dealer of record. See "Purchases -- Class A Shares"
above. In addition, to the extent that the aggregate service and distribution
fees paid under the Distribution Plan does not exceed 0.50% per annum of the
average daily net assets of a Fund attributable to Class A shares, the Fund is
permitted to pay such distribution-related expenses or other
distribution-related expenses.
 
     CLASS B SHARES.  Class B shares of each Fund are offered at net asset value
without an initial sales charge but subject to a CDSC. See "Purchases -- Class B
Shares" above. MFD will advance to dealers the first year service fee described
above at a rate equal to 0.25% of the purchase price of such shares and, as
compensation therefore, MFD may retain the service fee paid by the Fund with
respect to such shares for the first year after purchase. Dealers will become
eligible to receive the
    
 
                                       25
<PAGE>   39
 
ongoing 0.25% per annum service fee with respect to such shares commencing in
the thirteenth month following purchase.
 
   
     Under the Distribution Plan, the Fund pays MFD a distribution fee equal, on
an annual basis, to 0.75% of the Fund's average daily net assets attributable to
Class B shares. As noted above, this distribution fee may be used by MFD to
cover its distribution-related expenses under its distribution agreement with
each Fund (including the 3.75% commission it pays to dealers upon purchase of
Class B shares, as described under "Purchases -- Class B Shares" above).
 
     CLASS C SHARES.  Class C shares are offered at net asset value without an
initial sales charge but subject to a CDSC. See "Purchases -- Class C shares"
above. MFD will pay a commission to dealers of 1.00% of the purchase price of
Class C shares purchased through dealers at the time of purchase. In
compensation for this 1.00% commission paid by MFD to dealers, MFD will retain
the 1.00% per annum Class C distribution and service fees paid by the Fund with
respect to such shares for the first year after purchase, and dealers will
become eligible to receive from MFD the ongoing 1.00% per annum distribution and
service fees paid by the Fund to MFD with respect to such shares commencing in
the thirteenth month following purchase.
 
     This ongoing 1.00% fee is comprised of the 0.25% per annum service fee paid
to MFD under the Distribution Plan (which MFD in turn pays to dealers), as
discussed above, and a distribution fee paid to MFD (which MFD also in turn pays
to dealers) under the Distribution Plan equal, on an annual basis, to 0.75% of
the Fund's average daily net assets attributable to Class C shares.
    
 
     CURRENT LEVEL OF DISTRIBUTION AND SERVICE FEES: Each Fund's
distribution/service fee for its current fiscal year is equal to 0.50%, 1.00%
and 1.00% per annum of the average daily net assets attributable to the Fund's
Class A shares, Class B shares and Class C shares, respectively.
 
DISTRIBUTIONS
     Each Fund intends to pay substantially all of its net investment income as
dividends on an annual basis. In determining the net investment income available
for distributions, each Fund may rely on projections of its anticipated net
investment income over a longer term, rather than its actual net investment
income for the period. If a Fund earns less than projected, or otherwise
distributes more than its earnings for the year, a portion of the distributions
may constitute a return of capital. Each Fund may make one or more distributions
during the calendar year to its shareholders from any long-term capital gains,
and may also make one or more distributions during the calendar year to its
shareholders from short-term capital gains. Shareholders may elect to receive
dividends and capital gain distributions in either cash or additional shares of
the same class with respect to which a distribution is made. See "Tax Status"
and "Shareholder Services -- Distribution Options" below. Distributions paid by
each Fund with respect to Class A shares will generally be greater than those
paid with respect to Class B and Class C shares because expenses attributable to
Class B and Class C shares will generally be higher.
 
TAX STATUS
   
     Each Fund is treated as an entity separate from the other series of the
Trust for federal income tax purposes. In order to minimize the taxes each Fund
would otherwise be required to pay, each Fund intends to qualify each year as a
"regulated investment company" under Subchapter M of the Internal Revenue Code
of 1986, as amended (the "Code"). Because each Fund intends to distribute all of
its net investment income and net realized capital gains to its shareholders in
accordance with the timing requirements imposed by the Code, it is not expected
that the Funds will be required to pay federal income or excise taxes, although
each Fund's foreign-source income may be subject to foreign withholding taxes.
 
     Shareholders of each Fund normally will have to pay federal income taxes
(and any state or local taxes), on the dividends and capital gain distributions
they receive from the Fund, whether the distribution is in cash or in additional
shares. Shortly after the end of each calendar year, each shareholder will be
sent a statement setting forth the federal income tax status of all dividends
and distributions for that year, including the portion taxable as ordinary
income, the portion taxable as long-term capital gain, the portion, if any,
representing a return of capital (which is free of current taxes but results in
a basis reduction) and the amount, if any, of federal income tax withheld. In
certain circumstances, a Fund may also elect to "pass through" to shareholders
foreign income taxes paid by the Fund. Under those circumstances, the Fund will
notify shareholders of their pro rata portion of the foreign income taxes paid
by the Fund; shareholders may be eligible for foreign tax credits or deductions
with respect to those taxes, but will be required to treat the amount of the
taxes as an amount distributed to them and thus includible in their gross income
for federal income tax purposes.
    
 
     A Fund's distributions will reduce the Fund's net asset value per share.
Shareholders who buy shares shortly before a Fund makes a distribution may thus
pay the full price for the shares and then effectively receive a portion of the
purchase price back as a taxable distribution.
 
   
     Each Fund intends to withhold U.S. federal income tax at the rate of 30% on
dividends and other payments that are subject to such withholding and that are
made to persons who are neither citizens nor residents of the U.S., regardless
of whether a lower rate may be permitted
    
 
                                       26
<PAGE>   40
 
   
under an applicable treaty. Each Fund is also required in certain circumstances
to apply backup withholding at the rate of 31% on dividends and redemption
proceeds paid to any shareholder (including a shareholder who is neither a
citizen nor a resident of the U.S.) who does not furnish to the Fund certain
information and certifications or who is otherwise subject to backup
withholding. Backup withholding will not, however, be applied to payments which
have been subject to 30% withholding. Prospective investors should read the
Funds' Account Application for additional information regarding backup
withholding of federal income tax and should consult their own tax advisers as
to the tax consequences to them of an investment in a Fund.
    
 
NET ASSET VALUE
     The net asset value per share of each class of each Fund is determined each
day during which the Exchange is open for trading. This determination is made
once each day as of the close of regular trading on the Exchange by deducting
the amount of the liabilities attributable to the class from the value of the
assets attributable to the class and dividing the difference by the number of
shares of the class outstanding. Assets in each Fund's portfolio are valued on
the basis of their market values or otherwise at their fair values, as described
in the SAI. All investments and assets are expressed in U.S. dollars based upon
current currency exchange rates. The net asset value per share of each class of
shares is effective for orders received by the dealer prior to its calculation
and received by MFD prior to the close of that business day.
 
DESCRIPTION OF SHARES, VOTING RIGHTS AND LIABILITIES
   
     Each Fund has three classes of shares which it offers to the general
public, entitled Class A, Class B and Class C shares of Beneficial Interest
(without par value). Each Fund also has a class of shares which it offers
exclusively to certain institutional investors entitled Class I Shares. The
Trust has reserved the right to create and issue additional classes and series
of shares, in which case each class of shares of a series would participate
equally in the earnings, dividends and assets attributable to that class of that
particular series. Shareholders are entitled to one vote for each share held and
shares of each series are entitled to vote separately to approve investment
advisory agreements or changes in investment restrictions, but shares of all
series vote together in the election of Trustees and selection of accountants.
Additionally, each class of shares of a series will vote separately on any
material increases in the fees under the Distribution Plan or on any other
matter that affects solely that class of shares, but will otherwise vote
together with all other classes of shares of the series on all other matters.
The Trust does not intend to hold annual shareholder meetings. The Trust's
Declaration of Trust provides that a Trustee may be removed from office in
certain instances. See "Description of Shares, Voting Rights and Liabilities" in
the SAI.
    
 
     Each share of a class of each Fund represents an equal proportionate
interest in the Fund with each other class share, subject to the liabilities of
the particular class. Shares have no pre-emptive or conversion rights (except as
set forth in "Purchases -- Conversion of Class B shares"). Shares are fully paid
and non-assessable. Should a Fund be liquidated, shareholders of each class are
entitled to share pro rata in the net assets attributable to that class
available for distribution to shareholders. Shares will remain on deposit with
the Shareholder Servicing Agent and certificates will not be issued except in
connection with pledges and assignments and in certain other limited
circumstances.
 
     The Trust is an entity of the type commonly known as a "Massachusetts
business trust." Under Massachusetts law, shareholders of such a trust may,
under certain circumstances, be held personally liable as partners for its
obligations. However, the risk of a shareholder incurring financial loss on
account of shareholder liability would be limited to circumstances in which both
inadequate insurance existed and the Trust itself was unable to meet its
obligations.
 
PERFORMANCE INFORMATION
     From time to time, each Fund will provide total rate of return quotations
for each class of shares and may also quote fund rankings in the relevant fund
category from various sources, such as the Lipper Analytical Services, Inc. and
Wiesenberger Investment Companies Service. The International Growth and Income
Fund may also provide its yield and current distribution rate. Total rate of
return quotations will reflect the average annual percentage change over stated
periods in the value of an investment in a class of a Fund made at the maximum
public offering price of the shares of that class with all distributions
reinvested and which will give effect to the imposition of any applicable CDSC
assessed upon redemptions of the Fund's Class B and Class C shares. Such total
rate of return quotations may be accompanied by quotations which do not reflect
the reduction in value of the initial investment due to the sales charge or the
deduction of a CDSC, and which will thus be higher.
 
   
     Each Fund offers multiple classes of shares which were initially offered
for sale to the public on different dates. The calculation of total rate of
return for a class of shares which initially was offered for sale to the public
subsequent to another class of shares of each Fund is based both on (i) the
performance of each Fund's newer class from the date it initially was offered
for sale to the public and (ii) the performance of each Fund's oldest class from
the date it initially was offered for sale to the public up to the date that the
newer class initially was offered for sale to the public. See the SAI for
further information on the calculation of total rate of return for share classes
initially offered for sale to the public on different dates.
    
 
     Yield quotations will be based on the annualized net investment income per
share of a class of the International Growth and Income Fund over a 30-day
period stated as a percent of the maximum public offering price of shares of
that class on the last day of that period. Yield
 
                                       27
<PAGE>   41
 
calculations for Class B and Class C shares assume no CDSC is paid. The 
current distribution rate for each class is generally based upon the total 
amount of dividends per share paid by the International Growth and Income Fund 
to shareholders of that class during the past 12 months and is computed by 
dividing the amount of such dividends by the maximum public offering price of 
that class at the end of such period. Current distribution rate calculations 
for Class B and Class C shares assume no CDSC is paid. The current distribution 
rate differs from the yield calculation because it may include distributions 
to shareholders from sources other than dividends and interest, such as 
premium income from option writing, short-term capital gains, and return of 
invested capital, and is calculated over a different period of time.
 
     All performance quotations are based on historical performance and are not
intended to indicate future performance. Yield reflects only net portfolio
income as stated and current distribution rate reflects only the rate of
distributions paid by the International Growth and Income Fund over a stated
period of time. Each Fund's quotations may from time to time be used in
advertisements, shareholder reports or other communications to shareholders. For
a discussion of the manner in which a Fund will calculate its total rate of
return, yield and current distribution rate see the SAI. In addition to
information provided in shareholder reports, each Fund may, in its discretion,
from time to time make a list of all or a portion of its holdings available to
investors upon request.
 
EXPENSES
     The Trust pays the compensation of the Trustees who are not officers of MFS
and all expenses of each Fund (other than those assumed by MFS) including but
not limited to: governmental fees; interest charges; taxes; membership dues in
the Investment Company Institute allocable to a Fund; fees and expenses of
independent auditors, of legal counsel, and of any transfer agent, registrar or
dividend disbursing agent of a Fund; expenses of repurchasing and redeeming
shares and servicing shareholder accounts; expenses of preparing, printing and
mailing prospectuses, periodic reports, notices and proxy statements to
shareholders and to governmental officers and commissions; brokerage and other
expenses connected with the execution, recording and settlement of portfolio
security transactions; insurance premiums; fees and expenses of State Street
Bank and Trust Company, the Trust's Custodian, for all services to each Fund,
including safekeeping of funds and securities and maintaining required books and
accounts; expenses of calculating the net asset value of shares of a Fund; and
expenses of shareholder meetings. Expenses relating to the issuance,
registration and qualification of shares of a Fund and the preparation, printing
and mailing of prospectuses are borne by the Fund except that the Distribution
Agreement with MFD requires MFD to pay for prospectuses that are to be used for
sales purposes. Expenses of the Trust which are not attributable to a specific
series of the Trust are allocated among the series in a manner believed by
management of the Trust to be fair and equitable.
 
   
     Subject to termination or revision at the sole discretion of MFS, MFS has
agreed to bear the expenses of the Emerging Markets Equity Fund ("FEM") such
that FEM's "Other Expenses" which are defined to include all expenses of FEM
except for management fees, Rule 12b-1 fees, taxes, extraordinary expenses,
brokerage and termination costs and class specific expenses, do not exceed 0.75%
per annum of FEM's average daily net assets (the "Maximum Percentage"). The
obligation of MFS to bear these expenses terminates on the last day of FEM's
fiscal year in which FEM's "Other Expenses" are less than or equal to the
Maximum Percentage. The payments made by MFS on behalf of FEM under this
arrangement are subject to reimbursement by FEM to MFS, which will be
accomplished by the payment of an expense reimbursement fee by FEM to MFS
computed and paid monthly at a percentage of its average daily net assets for
its then current fiscal year, with a limitation that immediately after such
payment, FEM's "Other Expenses" will not exceed the Maximum Percentage. This
expense reimbursement by FEM to MFS terminates on the earlier of the date on
which payments made by FEM equal the prior payment of such reimbursable expenses
by MFS or December 31, 2005.

                           9.   SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------

     Shareholders with questions concerning the shareholder services described
below or concerning other aspects of a Fund, should contact the Shareholder
Servicing Agent (see back cover for address and phone number).
 
     ACCOUNT AND CONFIRMATION STATEMENTS -- Each shareholder will receive
confirmation statements showing the transaction activity in his account. At the
end of each calendar year, each shareholder will receive information regarding
the tax status of reportable dividends and distributions for that year (see "Tax
Status").
 
     DISTRIBUTION OPTIONS -- The following options are available to all accounts
(except Systematic Withdrawal Plan accounts described below) and may be changed
as often as desired by notifying the Shareholder Servicing Agent:
 
     -- Dividends and capital gain distributions reinvested in additional
        shares; this option will be assigned if no other option is specified.
 
                                       28
<PAGE>   42
 
     -- Dividends in cash; capital gain distributions reinvested in additional
        shares.
 
     -- Dividends and capital gain distributions in cash.
 
     Reinvestments (net of any tax withholding) will be made in additional full
and fractional shares of the same class of shares at the net asset value in
effect at the close of business on the record date. Dividends and capital gain
distributions in amounts less than $10 will automatically be reinvested in
additional shares of a Fund. If a shareholder has elected to receive dividends
and/or capital gain distributions in cash, and the postal or other delivery
service is unable to deliver checks to the shareholder's address of record, or
the shareholder does not respond to mailings from the Shareholder Servicing
Agent with regard to uncashed distribution checks, such shareholder's
distribution option will automatically be converted to having all dividends and
other distributions reinvested in additional shares. Any request to change a
distribution option must be received by the Shareholder Servicing Agent by the
record date for a dividend or distribution in order to be effective for that
dividend or distribution. No interest will accrue on amounts represented by
uncashed distribution or redemption checks.
 
     INVESTMENT AND WITHDRAWAL PROGRAMS -- For the convenience of shareholders,
each Fund makes available the following programs designed to enable shareholders
to add to their investment in an account with each Fund or withdraw from it with
a minimum of paper work. The programs involve no extra charge to shareholders
(other than a sales charge in the case of certain Class A share purchases) and
may be changed or discontinued at any time by a shareholder or a Fund:
 
     LETTER OF INTENT:  If a shareholder (other than a group purchaser as
described in the SAI) anticipates purchasing $100,000 or more of Class A shares
of a Fund alone or in combination with shares of any of the classes of other MFS
Funds or MFS Fixed Fund (a bank collective investment fund) within a 13-month
period (or 36-month period for purchases of $1 million or more), the shareholder
may obtain such shares at the same reduced sales charge as though the total
quantity were invested in one lump sum, subject to escrow agreements and the
appointment of an attorney for redemptions from the escrow amount if the
intended purchases are not completed, by completing the Letter of Intent section
of the Account Application.
 
   
     RIGHT OF ACCUMULATION:  A shareholder qualifies for cumulative quantity
discounts on purchases of Class A shares when his new investment, together with
the current offering price value of all holdings of Class A, B and C shares of
that shareholder in the MFS Funds or MFS Fixed Fund (a bank collective
investment fund) reaches a discount level.
    
 
     DISTRIBUTION INVESTMENT PROGRAM:  Shares of a particular class of a Fund
may be sold at net asset value (and not subject to any CDSC) through the
automatic reinvestment of dividend and capital gain distributions from the same
class of another MFS Fund. Furthermore, distributions made by a Fund may be
automatically invested at net asset value (and not subject to any CDSC) in
shares of the same class of another MFS Fund, if shares of such MFS Fund are
available for sale.
 
     SYSTEMATIC WITHDRAWAL PLAN:  A shareholder may direct the Shareholder
Servicing Agent to send to him (or any one he designates) regular periodic
payments, as designated on the account application, and based upon the value of
his account. Each payment under a Systematic Withdrawal Plan (a "SWP") must be
at least $100, except in certain limited circumstances. The aggregate
withdrawals of Class B and Class C shares in any year pursuant to a SWP will not
be subject to a CDSC and are generally limited to 10% of the value of the
account at the time of the establishment of the SWP. The CDSC will not be waived
in the case of SWP redemptions of Class A shares which are subject to a CDSC.
 
DOLLAR COST AVERAGING PROGRAMS
 
   
     AUTOMATIC INVESTMENT PLAN:  Cash investments of $50 or more may be made
through a shareholder's checking account on any day of the month. If the
shareholder does not specify a date, the investment will automatically occur on
the first business day of the month. Required forms are available from the
Shareholder Servicing Agent or investment dealers.
 
     AUTOMATIC EXCHANGE PLAN:  Shareholders having account balances of at least
$5,000 in any MFS Fund may participate in the Automatic Exchange Plan, a dollar
cost averaging program. The Automatic Exchange Plan provides for automatic
monthly or quarterly exchanges of funds from the shareholder's account in an MFS
Fund for investment in the same class of shares of other MFS Funds selected by
the shareholder (if available for sale). Under the Automatic Exchange Plan,
exchanges of at least $50 each may be made to up to six different funds. A
shareholder should consider the objectives and policies of a fund and review its
prospectus before electing to exchange money into such fund through the
Automatic Exchange Plan. No transaction fee is imposed in connection with
exchange transactions under the Automatic Exchange Plan. However, exchanges of
shares of MFS Money Market Fund, MFS Government Money Market Fund or Class A
shares of MFS Cash Reserve Fund will be subject to any applicable sales charge.
For federal and (generally) state income tax purposes, an exchange is treated as
a sale of the shares exchanged and, therefore, could result in a capital gain or
loss to the shareholder making the exchange. See the SAI for further information
concerning the Automatic Exchange Plan.
    
 
                                       29
<PAGE>   43
Investors should consult their tax advisers for information regarding the
potential capital gain and loss consequences of transactions under the Automatic
Exchange Plan.
 
     Because a dollar cost averaging program involves periodic purchases of
shares regardless of fluctuating share offering prices, a shareholder should
consider his financial ability to continue his purchases through periods of low
price levels. Maintaining an investment program concurrently with a withdrawal
program would be disadvantageous because of the sales charges included in share
purchases in the case of Class A shares, and because of the assessment of the
CDSC for share redemption (if applicable) in the case of Class A shares.
 
     TAX-DEFERRED RETIREMENT PLANS -- Shares of each Fund may be purchased by
all types of tax-deferred retirement plans, including IRAs, SEP-IRA plans,
401(k) plans, 403(b) plans and other corporate pension and profit-sharing plans.
Investors should consult with their tax adviser before establishing any of the
tax-deferred retirement plans described above.

       prior to the redemption, the aggregate amount invested by the 401(a) or
       ESP Plan in shares of the MFS Funds (excluding the reinvestment of
       distributions) during the prior four years equals 50% or more of the
       total value of the 401(a) or ESP Plan's assets in the MFS Funds, in which

                                   APPENDIX B
- --------------------------------------------------------------------------------

                          DESCRIPTION OF BOND RATINGS
 
                                    MOODY'S
 
     Aaa:  Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edged." Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.
 
     Aa:  Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long-term risk appear somewhat larger than in Aaa securities.
 
     A:  Bonds which are rated A possess many favorable investment attributes
and are to be considered as upper-medium-grade obligations. Factors giving
security to principal and interest are considered adequate, but elements may be
present which suggest a susceptibility to impairment some time in the future.
 
     Baa:  Bonds which are rated Baa are considered as medium-grade obligations,
(i.e., they are neither highly protected nor poorly secured). Interest payments
and principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Some bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.
 
     Ba:  Bonds which are rated Ba are judged to have speculative elements;
their future cannot be considered as well-assured. Often the protection of
interest and principal payments may be very moderate, and thereby not well
safeguarded during both good and bad times over the future. Uncertainty of
position characterizes bonds in this class.
 
     B:  Bonds which are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.
 
     Caa:  Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.
 
     Ca:  Bonds which are rated Ca represent obligations which are speculative
in a high degree. Such issues are often in default or have other marked
shortcomings.
 
     C:  Bonds which are rated C are the lowest rated class of bonds, and issues
so rated can be regarded as having extremely poor prospects of ever attaining
any real investment standing.
 
     ABSENCE OF RATING:  Where no rating has been assigned or where a rating has
been suspended or withdrawn, it may be for reasons unrelated to the quality of
the issue.
 
     Should no rating be assigned, the reason may be one of the following:
 
     1. An application for rating was not received or accepted.
 
     2. The issue or issuer belongs to a group of securities or companies that
are not rated as a matter of policy.
 
     3. There is a lack of essential data pertaining to the issue or issuer.
 
     4. The issue was privately placed, in which case the rating is not
published in Moody's publications.
 
     Suspension or withdrawal may occur if new and material circumstances arise,
the effects of which preclude satisfactory analysis; if there is no longer
available reasonable up-to-date data to permit a judgment to be formed; if a
bond is called for redemption; or for other reasons.
 
     NOTE:  Moody's applies numerical modifiers, 1, 2 and 3 in each generic
rating classification from Aa to B. The modifier 1 indicates that the company
ranks in the higher end of its generic rating category; the modifier 2 indicates
a mid-range ranking; and the modifier 3 indicates that the company ranks in the
lower end of its generic rating category.
 
                                     S & P
 
     AAA:  Debt rated AAA has the highest rating assigned by S & P. Capacity to
pay interest and repay principal is extremely strong.
 
     AA:  Debt rated AA has a very strong capacity to pay interest and repay
principal and differs from the higher rated issues only in small degree.
 
     A:  Debt rated A has a strong capacity to pay interest and repay principal
although it is somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than debt in higher rated categories.
 
     BBB:  Debt rated BBB is regarded as having an adequate capacity to pay
interest and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circum-
 
                                       33
<PAGE>   47
 
stances are more likely to lead to a weakened capacity to pay interest and repay
principal for debt in this category than in higher rated categories.
 
     BB:  Debt rated BB has less near-term vulnerability to default than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse business, financial, or economic conditions which could lead to
inadequate capacity to meet timely interest and principal payments. The BB
rating category is also used for debt subordinated to senior debt that is
assigned an actual or implied BBB - rating.
 
     B:  Debt rated B has a greater vulnerability to default but currently has
the capacity to meet interest payments and principal repayments. Adverse
business, financial, or economic conditions will likely impair capacity or
willingness to pay interest and repay principal. The B rating category is also
used for debt subordinated to senior debt that is assigned an actual or implied
BB or BB- rating.
 
     CCC:  Debt rated CCC has a currently identifiable vulnerability to default,
and is dependent upon favorable business, financial, and economic conditions to
meet timely payment of interest and repayment of principal. In the event of
adverse business, financial, or economic conditions, it is not likely to have
the capacity to pay interest and repay principal. The CCC rating category is
also used for debt subordinated to senior debt that is assigned an actual or
implied B or B- rating.
 
     CC:  The rating CC is typically applied to debt subordinated to senior debt
that is assigned an actual or implied CCC rating.
 
     C:  The rating C is typically applied to debt subordinated to senior debt
which is assigned an actual or implied CCC- debt rating. The C rating may be
used to cover a situation where a bankruptcy petition has been filed, but debt
service payments are continued.
 
     CI:  The rating CI is reserved for income bonds on which no interest is
being paid.
 
     D:  Debt rated D is in payment default. The D rating category is used when
interest payments or principal payments are not made on the date due even if the
applicable grace period has not expired, unless S&P believes that such payments
will be made during such grace period. The "D" rating also will be used upon the
filing of a bankruptcy petition if debt service payments are jeopardized.
 
     PLUS (+) OR MINUS (-):  The ratings from AA to CCC may be modified by the
addition of a plus or minus sign to show relative standing within the major
categories.
 
     NR  indicates that no public rating has been requested, that there is
insufficient information on which to base a rating, or that S&P does not rate a
particular type of obligation as a matter of policy.

     AAA:  Bonds considered to be investment grade and of the highest credit
quality. The obligor has an exceptionally strong ability to pay interest and
repay principal, which is unlikely to be affected by reasonably foreseeable
events.
 
     AA:  Bonds considered to be investment grade and of very high credit
quality. The obligor's ability to pay interest and repay principal is very
strong, although not quite as strong as bonds rated 'AAA.' Because bonds rated
in the 'AAA' and 'AA' categories are not significantly vulnerable to foreseeable
future developments, short-term debt of these issuers is generally rated
'F-1+'.
 
     A:  Bonds considered to be investment grade and of very high credit
quality. The obligor's ability to pay interest and repay principal is considered
to be strong, but may be more vulnerable to adverse changes in economic
conditions and circumstances than bonds with higher ratings.
 
     BBB:  Bonds considered to be investment grade and of satisfactory credit
quality. The obligor's ability to pay interest and repay principal is considered
to be adequate. Adverse changes in economic conditions and circumstances,
however, are more likely to have adverse impact on these bonds, and therefore
impair timely payment. The likelihood that the ratings of these bonds will fall
below investment grade is higher than for bonds with higher ratings.
 
     BB:  Bonds are considered speculative. The obligor's ability to pay
interest and repay principal may be affected over time by adverse economic
changes. However, business and financial alternatives can be identified which
could assist the obligor in satisfying its debt service requirements.
 
     B:  Bonds are considered highly speculative. While bonds in this class are
currently meeting debt service requirements, the probability of continued timely
payment of principal and interest reflects the obligor's limited margin of
safety and the need for reasonable business and economic activity throughout the
life of the issue.
 
     CCC:  Bonds have certain identifiable characteristics which, if not
remedied, may lead to default. The ability to meet obligations requires an
advantageous business and economic environment.
 
     CC:  Bonds are minimally protected. Default in payment of interest and/or
principal seems probable over time.
 
     C:  Bonds are in imminent default in payment of interest or principal.

     PLUS (+) MINUS (-)  Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus and
minus signs, however, are not used in the 'AAA' category.
 
     NR  Indicates that Fitch does not rate the specific issue.
 
     CONDITIONAL  A conditional rating is premised on the successful completion
of a project or the occurrence of a specific event.
 
     SUSPENDED  A rating is suspended when Fitch deems the amount of information
available from the issuer to be inadequate for rating purposes.
 
     WITHDRAWN  A rating will be withdrawn when an issue matures or is called or
refinanced, and, at Fitch's discretion, when an issuer fails to furnish proper
and timely information.
 
     FITCHALERT  Ratings are placed on FitchAlert to notify investors of an
occurrence that is likely to result in a rating change and the likely direction
of such change. These are designated as "Positive," indicating a potential
upgrade, "Negative," for potential downgrade, or "Evolving," where ratings may
be lowered, FitchAlert is relatively short-term, and should be resolved within
12 months.

                        DUFF & PHELPS SHORT-TERM RATINGS
 
     D-1 +:  Highest certainty of timely payment. Short-term liquidity,
including internal operation factors and/or access to alternative sources of
funds, is outstanding and safety is just below risk-free U.S. Treasury
short-term obligations.
 
     D-1:  Very high certainty of timely payment. Liquidity factors are
excellent and supported by good fundamental protection factors. Risk factors are
minor.
 
     D-1 -:  High certainty of timely payment. Liquidity factors are strong and
supported by good fundamental protection factors. Risk factors are very small.
 
     D-2:  Good certainty of timely payment. Liquidity factors and company
fundamentals are sound. Although ongoing funding needs may enlarge total
financing requirements, access to capital markets is good. Risk factors are
small.
 
     D-3:  Satisfactory liquidity and other protection factors qualify issues as
to investment grade. Risk factors are larger and subject to more variation.
Nevertheless, timely payment is expected.
 
     D-4:  Speculative investment characteristics. Liquidity is not sufficient
to insure against disruption in debt service. Operating factors and market
access may be subject to a high degree of variation.
 
     D-5:  Issuer failed to meet scheduled principal and/or interest payments.

2. INVESTMENT POLICIES AND RESTRICTIONS
 
INVESTMENT POLICIES: The investment policies of each Fund are described in the
Prospectus and below. The following discussion of the Funds' investment policies
and restrictions supplements and should be read in conjunction with the
information set forth in the "Investment Objective and Policies" section of the
Prospectus.
 
FOREIGN SECURITIES: Each Fund may invest up to 100% of its assets in foreign
securities as discussed in the Prospectus. Investments in foreign issues involve
considerations and possible risks not typically associated with investments in
securities issued by domestic companies or with debt securities issued by
foreign governments. There may be less publicly available information about a
foreign company than about a domestic company, and many foreign companies are
not subject to accounting, auditing and financial reporting standards and
requirements comparable to those to which U.S. companies are subject. Foreign
securities markets, while growing in volume, have substantially less volume than
U.S. markets, and securities of many foreign companies are less liquid and their
prices more volatile than securities of comparable domestic companies. Fixed
brokerage commissions and other transaction costs on foreign securities
exchanges are generally higher than in the U.S. There is also less government
supervision and regulation of exchanges, brokers and issuers in foreign
countries than there is in the U.S.
 
EMERGING MARKETS: Each of the Funds may invest in securities of government,
government-related, supranational and corporate issuers located in emerging
markets. Such investments entail significant risks as described in the
Prospectus under the caption "Risk Factors" and as more fully described below.
 
     COMPANY DEBT -- Governments of many emerging market countries have
exercised and continue to exercise substantial influence over many aspects of
the private sector through the ownership or control of many companies, including
some of the largest in any given country. As a result, government actions in the
future could have a significant effect on economic conditions in emerging
markets, which in turn, may adversely affect companies in the private sector,
general market conditions and prices and yields of certain of the securities in
a Fund's portfolio. Expropriation, confiscatory taxation, nationalization,
political, economic or social instability or other similar developments have
occurred frequently over the history of certain emerging markets and could
adversely affect a Fund's assets should these conditions recur.
 
     SOVEREIGN DEBT -- Investment in sovereign debt can involve a high degree of
risk. The governmental entity that controls the repayment of sovereign debt may
not be able or willing to repay the principal and/or interest when due in
accordance with the terms of such debt. A governmental entity's willingness or
ability to repay principal and interest due in a timely manner may be affected
by, among other factors, its cash flow situation, the extent of its foreign
reserves, the availability of sufficient foreign exchange on the date a payment
is due, the relative size of the debt service burden to the economy as a whole,
the governmental entity's policy towards the International Monetary Fund and the
political constraints to which a governmental entity may be subject.
Governmental entities may also be dependent on expected disbursements from
foreign governments, multilateral agencies and others abroad to reduce principal
and interest on their debt. The commitment on the part of these
 
                                        2
<PAGE>   52
 
governments, agencies and others to make such disbursements may be conditioned
on a governmental entity's implementation of economic reforms and/or economic
performance and the timely service of such debtor's obligations. Failure to
implement such reforms, achieve such levels of economic performance or repay
principal or interest when due may result in the cancellation of such third
parties' commitments to lend funds to the governmental entity, which may further
impair such debtor's ability or willingness to service its debts in a timely
manner. Consequently, governmental entities may default on their sovereign debt.
Holders of sovereign debt (including a Fund) may be requested to participate in
the rescheduling of such debt and to extend further loans to governmental
entities. There is no bankruptcy proceeding by which sovereign debt on which
governmental entities have defaulted may be collected in whole or in part.
 
Emerging market governmental issuers are among the largest debtors to commercial
banks, foreign governments, international financial organizations and other
financial institutions. Certain emerging market governmental issuers have not
been able to make payments of interest on or principal of debt obligations as
those payments have come due. Obligations arising from past restructuring
agreements may affect the economic performance and political and social
stability of those issuers.
 
The ability of emerging market governmental issuers to make timely payments on
their obligations is likely to be influenced strongly by the issuer's balance of
payments, including export performance, and its access to international credits
and investments. An emerging market whose exports are concentrated in a few
commodities could be vulnerable to a decline in the international prices of one
or more of those commodities. Increased protectionism on the part of an emerging
market's trading partners could also adversely affect the country's exports and
tarnish its trade account surplus, if any. To the extent that emerging markets
receive payment for their exports in currencies other than dollars or
non-emerging market currencies, its ability to make debt payments denominated in
dollars or non-emerging market currencies could be affected.
 
To the extent that an emerging market country cannot generate a trade surplus,
it must depend on continuing loans from foreign governments, multilateral
organizations or private commercial banks, aid payments from foreign governments
and on inflows of foreign investment. The access of emerging markets to these
forms of external funding may not be certain, and a withdrawal of external
funding could adversely affect the capacity of emerging market country
governmental issuers to make payments on their obligations. In addition, the
cost of servicing emerging market debt obligations can be affected by a change
in international interest rates since the majority of these obligations carry
interest rates that are adjusted periodically based upon international rates.
 
Another factor bearing on the ability of emerging market countries to repay debt
obligations is the level of international reserves of the country. Fluctuations
in the level of these reserves affect the amount of foreign exchange readily
available for external debt payments and thus could have a bearing on the
capacity of emerging market countries to make payments on these debt
obligations.
 
     LIQUIDITY; TRADING VOLUME; REGULATORY OVERSIGHT -- The securities markets
of emerging market countries are substantially smaller, less developed, less
liquid and more volatile than the major securities markets in the U.S.
Disclosure and regulatory standards are in many respects less stringent than
U.S. standards. Furthermore, there is a lower level of monitoring and regulation
of the markets and the activities of investors in such markets.
 
The limited size of many emerging market securities markets and limited trading
volume in the securities of emerging market issuers compared to volume of
trading in the securities of U.S. issuers could cause prices to be erratic for
reasons apart from factors that affect the soundness and competitiveness of the
securities issuers. For example, limited market size may cause prices to be
unduly influenced by traders who control large positions. Adverse publicity and
investors' perceptions, whether or not based on in-depth fundamental analysis,
may decrease the value and liquidity of portfolio securities.
 
The risk also exists that an emergency situation may arise in one or more
emerging markets, as a result of which trading of securities may cease or may be
substantially curtailed and prices for a Fund's securities in such markets may
not be readily available. The Trust may suspend redemption of its shares for any
period during which an emergency exists, as determined by the Securities and
Exchange Commission (the "SEC"). Accordingly, if a Fund believes that
appropriate circumstances exist, it will promptly apply to the SEC for a
determination that an emergency is present. During the period commencing from
the Fund's identification of such condition until the date of the SEC action,
the Fund's securities in the affected markets will be valued at fair value
determined in good faith by or under the direction of the Board of Trustees.
 
     DEFAULT; LEGAL RECOURSE -- A Fund may have limited legal recourse in the
event of a default with respect to certain debt obligations it may hold. If the
issuer of a fixed-income security owned by a Fund defaults, the Fund may incur
additional expenses to seek recovery. Debt obligations issued by emerging market
governments differ from debt obligations of private entities; remedies from
defaults on debt obligations issued by emerging market governments, unlike those
on private debt, must be pursued in the courts of the defaulting party itself. A
Fund's ability to enforce its rights against private issuers may be limited. The
ability to attach assets to enforce a judgment may be limited. Legal recourse is
therefore somewhat diminished. Bankruptcy, moratorium and other similar laws
applicable to private
 
                                        3
<PAGE>   53
 
issuers of debt obligations may be substantially different from those of other
countries. The political context, expressed as an emerging market governmental
issuer's willingness to meet the terms of the debt obligation, for example, is
of considerable importance. In addition, no assurance can be given that the
holders of commercial bank debt may not contest payments to the holders of debt
obligations in the event of default under commercial bank loan agreements.
 
     INFLATION -- Many emerging markets have experienced substantial, and in
some periods extremely high, rates of inflation for many years. Inflation and
rapid fluctuations in inflation rates have had and may continue to have adverse
effects on the economies and securities markets of certain emerging market
countries. In an attempt to control inflation, wage and price controls have been
imposed in certain countries. Of these countries, some, in recent years, have
begun to control inflation through prudent economic policies.
 
     WITHHOLDING -- Income from securities held by a Fund could be reduced by a
withholding tax on the source or other taxes imposed by the emerging market
countries in which the Fund makes its investments. A Fund's net asset value may
also be affected by changes in the rates or methods of taxation applicable to
the Fund or to entities in which the Fund has invested. The Adviser and the Sub-
Adviser will consider the cost of any taxes in determining whether to acquire
any particular investments, but can provide no assurance that the taxes will not
be subject to change.
 
     FOREIGN CURRENCIES -- Each Fund may invest up to 100% of its assets in
securities denominated in foreign currencies. Accordingly, changes in the value
of these currencies against the U.S. dollar may result in corresponding changes
in the U.S. dollar value of a Fund's assets denominated in those currencies.
Each Fund may attempt to minimize the impact of these changes to the U.S. dollar
value of the Fund's portfolio by engaging in certain hedging practices, such as
entering into Futures Contracts and Options on Foreign Securities as described
below.
 
Some emerging market countries also may have managed currencies, which are not
free floating against the U.S. dollar. In addition, there is risk that certain
emerging market countries may restrict the free conversion of their currencies
into other currencies. Further, certain emerging market currencies may not be
internationally traded. Certain of these currencies have experienced a steep
devaluation relative to the U.S. dollar. Any devaluations in the currencies in
which a Fund's portfolio securities are denominated may have a detrimental
impact on the Fund's net asset value.
 
INVESTMENT IN OTHER INVESTMENT COMPANIES: A Fund's investment in other
investment companies, as described in the Prospectus, is limited in amount by
the Investment Company Act of 1940, as amended (the "1940 Act"), and applicable
state securities laws. Such investment may also involve the payment of
substantial premiums above the value of such investment companies' portfolio
securities, and the total return on such investment will be reduced by the
operating expenses and fees of such other investment companies, including
advisory fees.
 
REPURCHASE AGREEMENTS: Each Fund may enter into repurchase agreements with
sellers who are member firms (or a subsidiary thereof) of the New York Stock
Exchange (the "Exchange"), members of the Federal Reserve System, recognized
domestic or foreign securities dealers or institutions which the Adviser or the
Sub-Adviser has determined to be of comparable creditworthiness. The securities
that a Fund purchases and holds have values which are equal to or greater than
the repurchase price agreed to be paid by the seller. The repurchase price may
be higher than the purchase price, the difference being income to the Fund, or
the purchase and repurchase prices may be the same, with interest at a standard
rate due to the Fund together with the repurchase price on repurchase.
 
The repurchase agreement provides that in the event the seller fails to pay the
price agreed upon on the agreed upon delivery date or upon demand, as the case
may be, a Fund will have the right to liquidate the securities. If at the time
the Fund is contractually entitled to exercise its right to liquidate the
securities, the seller is subject to a proceeding under the bankruptcy laws or
its assets are otherwise subject to a stay order, the Fund's exercise of its
right to liquidate the securities may be delayed and result in certain losses
and costs to the Fund. Each Fund has adopted and follows procedures which are
intended to minimize the risks of repurchase agreements. For example, a Fund
only enters into repurchase agreements after the Adviser or the Sub-Adviser has
determined that the seller is creditworthy, and the Adviser or the Sub-Adviser
monitors that seller's creditworthiness on an ongoing basis. Moreover, under
such agreements, the value of the securities (which are marked to market every
business day) is required to be greater than the repurchase price, and the Fund
has the right to make margin calls at any time if the value of the securities
falls below the agreed upon margin.
 
DEPOSITARY RECEIPTS: Each Fund may invest in American Depositary Receipts
("ADRs") which are certificates issued by a U.S. depository (usually a bank) and
represent a specified quantity of shares of an underlying non-U.S. stock on
deposit with a custodian bank as collateral. ADRs may be sponsored or
unsponsored. A sponsored ADR is issued by a depository which has an exclusive
relationship with the issuer of the underlying security. An unsponsored ADR may
be issued by any number of U.S. depositories. Under the terms of most sponsored
arrangements, depositories agree to distribute notices of shareholder meetings
and voting instructions, and to provide shareholder communications and other
information to the ADR holders at the request of the issuer of the deposited
securities. The depository of an unsponsored ADR, on the other hand, is under no
obligation to distribute shareholder communications received from the
 
                                        4
<PAGE>   54
 
issuer of the deposited securities or to pass through voting rights to ADR
holders in respect of the deposited securities. Each Fund may invest in either
type of ADR. Although the U.S. investor holds a substitute receipt of ownership
rather than direct stock certificates, the use of the depositary receipts in the
United States can reduce costs and delays as well as potential currency exchange
and other difficulties. Each Fund may purchase securities in local markets and
direct delivery of these ordinary shares to the local depository of an ADR agent
bank in the foreign country. Simultaneously, the ADR agents create a certificate
which settles at the Fund's custodian in five days. Each Fund may also execute
trades on the U.S. markets using existing ADRs. A foreign issuer of the security
underlying an ADR is generally not subject to the same reporting requirements in
the United States as a domestic issuer. Accordingly, information available to a
U.S. investor will be limited to the information the foreign issuer is required
to disclose in its own country and the market value of an ADR may not reflect
undisclosed material information concerning the issuer of the underlying
security. ADRs may also be subject to exchange rate risks if the underlying
foreign securities are denominated in a foreign currency. Each Fund may also
invest in Global Depositary Receipts ("GDRs") and other types of depositary
receipts. GDRs and other types of depositary receipts are typically issued by
foreign banks or trust companies and evidence ownership of underlying securities
issued by either a foreign or U.S. company.
 
LOANS AND OTHER DIRECT INDEBTEDNESS: Each Fund may purchase loans and other
direct claims against an issuer of emerging market debt instruments (a
"borrower"). In purchasing a loan, a Fund acquires some or all of the interest
of a bank or other lending institution in a loan to a corporate, governmental or
other borrower. Many such loans are secured, although some may be unsecured.
Such loans may be in default at the time of purchase. Loans that are fully
secured offer a Fund more protection than an unsecured loan in the event of
non-payment of scheduled interest or principal. However, there is no assurance
that the liquidation of collateral from a secured loan would satisfy the
corporate borrower's obligation, or that the collateral can be liquidated.
 
   
Certain of the loans acquired by a Fund may involve revolving credit facilities
or other standby financing commitments which obligate the Fund to pay additional
cash on a certain date or on demand. These commitments may have the effect of
requiring a Fund to increase its investment in a company at a time when the Fund
might not otherwise decide to do so (including at a time when the company's
financial condition makes it unlikely that such amounts will be repaid). To the
extent that a Fund is committed to advance additional funds, it will at all
times hold and maintain in a segregated account liquid assets in an amount
sufficient to meet such commitments.
    
 
A Fund's ability to receive payments of principal, interest and other amounts
due in connection with these investments will depend primarily on the financial
condition of the borrower. Direct indebtedness of developing countries involves
the risk that the governmental entities responsible for the repayment of the
note may be unable, or unwilling, to pay interest and repay principal where due.
In selecting the loans and other direct investments which a Fund will purchase,
the Adviser will rely upon its (and not that of the original lending
institution's) own credit analysis of the borrower. As a Fund may be required to
rely upon another lending institution to collect and pass on to the Fund amounts
payable with respect to the loan and to enforce the Fund's rights under the
loan, an insolvency, bankruptcy or reorganization of the lending institution may
delay or prevent the Fund from receiving such amounts. In such cases, the Fund
will evaluate as well the creditworthiness of the lending institution and will
treat both the borrower and the lending institution as an "issuer" of the loan
for purposes of certain investment restrictions pertaining to the
diversification of the Fund's portfolio investments. The highly leveraged nature
of many such loans may make such loans especially vulnerable to adverse changes
in economic or market conditions. Investments in such loans may involve
additional risks to a Fund.
 
   
WHEN-ISSUED OR FORWARD DELIVERY SECURITIES: When a Fund commits to purchase a
security on a "when-issued" or "forward delivery" basis, it will set up
procedures consistent with the General Statement of Policy of the SEC concerning
such purchases. Since that policy currently recommends that an amount of each
Fund's assets equal to the amount of the purchase be held aside or segregated to
be used to pay for the commitment, a Fund will always have liquid assets
sufficient to cover any commitments or to limit any potential risk. However,
although a Fund does not intend to make such purchases for speculative purposes
and intends to adhere to the provisions of the SEC policy, purchases of
securities on such bases may involve more risk than other types of purchases.
For example, a Fund may have to sell assets which have been set aside in order
to meet redemptions. Also, if a Fund determines it necessary to sell the
"when-issued" or "forward delivery" securities before delivery, it may incur a
loss because of market fluctuations since the time the commitment to purchase
such securities was made.
    
 
LENDING OF SECURITIES: Each Fund may seek to increase its income by lending
portfolio securities to entities deemed creditworthy by the Adviser or the
Sub-Adviser. Such loans would be required to be secured continuously by
collateral in cash, irrevocable letters of credit or U.S. Government securities
maintained on a current basis at an amount at least equal to the market value of
the securities loaned. Each Fund would have the right to call a loan and obtain
the securities loaned at any time on customary industry settlement notice (which
will usually not exceed five days). During the existence of a loan, a Fund would
continue to receive the equivalent of the interest or dividends paid by
 
                                        5
<PAGE>   55
 
the issuer on the securities loaned and would also receive compensation based on
investment of the cash collateral or a fee. A Fund would not, however, have the
right to vote any securities having voting rights during the existence of the
loan, but would call the loan in anticipation of an important vote to be taken
among holders of the securities or of the giving or withholding of their consent
on a material matter affecting the investment. As with other extensions of
credit there are risks of delay in recovery or even loss of rights in the
collateral should the borrower of the securities fail financially. However, the
loans would be made only to firms deemed by the Adviser and the Sub-Adviser to
be of good standing, and when, in the judgment of the Adviser or the
Sub-Adviser, the consideration which could be earned currently from securities
loans of this type justifies the attendant risk. If the Adviser or the
Sub-Adviser determines to make securities loans, it is not intended that the
value of the securities loaned would exceed 30% of the value of the Fund's total
assets.
 
WARRANTS: Each Fund will not invest more than 10% of its net assets, taken at
market value, in warrants not acquired in a unit transaction. Warrants are
securities that give a Fund the right to purchase equity securities from the
issuer at a specific price (the "strike price") for a limited period of time.
The strike price of warrants typically is much lower than the current market
price of the underlying securities, yet they are subject to similar price
fluctuations. As a result, warrants may be more volatile investments than the
underlying securities and may offer greater potential for capital appreciation
as well as capital loss.
 
Warrants do not entitle a holder to dividends or voting rights with respect to
the underlying securities and do not represent any rights in the assets of the
issuing company. Also, the value of the warrant does not necessarily change with
the value of the underlying securities and a warrant ceases to have value if it
is not exercised prior to the expiration date. These factors can make warrants
more speculative than other types of investments.
 
   
OPTIONS ON SECURITIES: Each Fund may write (sell) covered call and put options
on securities ("Options") and purchase call and put Options. An Option provides
the purchaser, or "holder", with the right, but not the obligation, to purchase,
in the case of a "call" Option, or sell, in the case of a "put" Option, the
security or securities in connection with which the Option was written, for a
fixed exercise price up to a stated expiration date or, in the case of certain
options, on such date. The holder pays a non-refundable purchase price for the
Option, known as the "premium." The maximum amount of risk the purchaser of the
Option assumes is equal to the premium plus related transaction costs, although
this entire amount may be lost. The risk of the seller, or "writer", however, is
potentially unlimited, unless the Option is "covered." A call option written by
a Fund is "covered" if the Fund owns the security underlying the call or has an
absolute and immediate right to acquire that security without additional cash
consideration (or for additional cash consideration held in a segregated account
by its custodian) upon conversion or exchange of other securities held in its
portfolio. A call option is also covered if a Fund holds a call on the same
security and in the same principal amount as the call written where the exercise
price of the call held (a) is equal to or less than the exercise price of the
call written or (b) is greater than the exercise price of the call written if
the difference is maintained by the Fund in liquid assets in a segregated
account with its custodian. A put option written by a Fund is "covered" if the
Fund maintains liquid assets with a value equal to the exercise price in a
segregated account with its custodian, or else holds a put on the same security
and in the same principal amount as the put written where the exercise price of
the put held is (a) equal to or greater than the exercise price of the put
written or (b) is less than the exercise price of the put written if the
difference is maintained by the Fund in liquid assets in a segregated account
with its custodian. Put and call options written by a Fund may also be covered
in such other manner as may be in accordance with the requirements of the
exchange on which, or the counter party with which the option is traded, and
applicable laws and regulations. If the writer's obligation is not so covered,
it is subject to the risk of the full change in value of the underlying security
from the time the option is written until exercise.
    
 
Each Fund may write Options for the purpose of increasing its return and for
hedging purposes. In particular, if a Fund writes an Option which expires
unexercised or is closed out by the Fund at a profit, the Fund retains the
premium paid for the Option less related transaction costs, which increases its
gross income and offsets in part the reduced value of the portfolio security in
connection with which the Option is written, or the increased cost of portfolio
securities to be acquired. In contrast, however, if the price of the security
underlying the Option moves adversely to the Fund's position, the Option may be
exercised and the Fund will then be required to purchase or sell the security at
a disadvantageous price, which might only partially be offset by the amount of
the premium.
 
Each Fund may write Options in connection with buy-and-write transactions; that
is, a Fund may purchase a security and then write a call Option against that
security. The exercise price of the call Option the Fund determines to write
depends upon the expected price movement of the underlying security. The
exercise price of a call Option may be below ("in-the-money"), equal to
("at-the-money") or above ("out-of-the-money") the current value of the
underlying security at the time the Option is written.
 
The writing of covered put Options is similar in terms of risk/return
characteristics to buy-and-write transactions. Put Options may be used by a Fund
in the same market environments in which call Options are used in equivalent
buy-and-write transactions.
 
                                        6
<PAGE>   56
 
Each Fund may also write combinations of put and call Options on the same
security, a practice known as a "straddle." By writing a straddle, a Fund
undertakes a simultaneous obligation to sell or purchase the same security in
the event that one of the Options is exercised. If the price of the security
subsequently rises sufficiently above the exercise price to cover the amount of
the premium and transaction costs, the call will likely be exercised and the
Fund will be required to sell the underlying security at a below market price.
This loss may be offset, however, in whole or in part, by the premiums received
on the writing of the two Options. Conversely, if the price of the security
declines by a sufficient amount, the put will likely be exercised. The writing
of straddles will likely be effective, therefore, only where the price of a
security remains stable and neither the call nor the put is exercised. In an
instance where one of the Options is exercised, the loss on the purchase or sale
of the underlying security may exceed the amount of the premiums received.
 
By writing a call Option on a portfolio security, a Fund limits its opportunity
to profit from any increase in the market value of the underlying security above
the exercise price of the Option. By writing a put Option, a Fund assumes the
risk that it may be required to purchase the underlying security for an exercise
price above its then current market value, resulting in a loss unless the
security subsequently appreciates in value. The writing of Options will not be
undertaken by a Fund solely for hedging purposes, and may involve certain risks
which are not present in the case of hedging transactions. Moreover, even where
Options are written for hedging purposes, such transactions will constitute only
a partial hedge against declines in the value of portfolio securities or against
increases in the value of securities to be acquired, up to the amount of the
premium.
 
Each Fund may also purchase put and call Options. Put Options are purchased to
hedge against a decline in the value of securities held in the Fund's portfolio.
If such a decline occurs, the put Options will permit the Fund to sell the
securities underlying such Options at the exercise price, or to close out the
Options at a profit. A Fund will purchase call Options to hedge against an
increase in the price of securities that the Fund anticipates purchasing in the
future. If such an increase occurs, the call Option will permit the Fund to
purchase the securities underlying such Option at the exercise price or to close
out the Option at a profit. The premium paid for a call or put Option plus any
transaction costs will reduce the benefit, if any, realized by the Fund upon
exercise of the Option, and, unless the price of the underlying security rises
or declines sufficiently, the Option may expire worthless to the Fund. In
addition, in the event that the price of the security in connection with which
an Option was purchased moves in a direction favorable to a Fund, the benefits
realized by the Fund as a result of such favorable movement will be reduced by
the amount of the premium paid for the Option and related transaction costs.
 
The staff of the SEC has taken the position that purchased over-the-counter
Options and assets used to cover written over-the-counter Options are illiquid
and, therefore, together with other illiquid securities, cannot exceed 15% of a
Fund's assets. Although the Adviser disagrees with this position, the Adviser
intends to limit each Fund's writing of over-the-counter Options in accordance
with the following procedure. Except as provided below, the Fund intends to
write over-the-counter Options only with primary U.S. Government securities
dealers recognized by the Federal Reserve Bank of New York. Also, the contracts
each Fund has in place with such primary dealers will provide that the Fund has
the absolute right to repurchase an Option it writes at any time at a price
which represents the fair market value, as determined in good faith through
negotiation between the parties, but which in no event will exceed a price
determined pursuant to a formula in the contract. Although the specific formula
may vary between contracts with different primary dealers, the formula will
generally be based on a multiple of the premium received by a Fund for writing
the Option, plus the amount, if any, of the Option's intrinsic value (i.e., the
amount that the Option is in-the-money). The formula may also include a factor
to account for the difference between the price of the security and the strike
price of the Option if the Option is written out-of-the-money. Each Fund will
treat all or a portion of the formula as illiquid for purposes of the 15% test
imposed by the SEC staff. The Fund may also write over-the-counter Options with
non-primary dealers, including foreign dealers, and will treat the assets used
to cover these Options as illiquid for purposes of such 15% test.
 
   
OPTIONS ON STOCK INDICES: As noted in the Prospectus, each Fund may write (sell)
covered call and put options and purchase call and put options on stock indices
("Options on Stock Indices"). The Fund may cover call Options on Stock Indices
by owning securities whose price changes, in the opinion of the Adviser or the
Sub-Adviser, are expected to be similar to those of the underlying index, or by
having an absolute and immediate right to acquire such securities without
additional cash consideration (or for additional cash consideration held in a
segregated account by its custodian) upon conversion or exchange of other
securities in its portfolio. Where a Fund covers a call option on a stock index
through ownership of securities, such securities may not match the composition
of the index and, in that event, the Fund will not be fully covered and could be
subject to risk of loss in the event of adverse changes in the value of the
index. Each Fund may also cover call options on stock indices by holding a call
on the same index and in the same principal amount as the call written where the
exercise price of the call held (a) is equal to or less than the exercise price
of the call written or (b) is greater than the exercise price of the call
written if the difference is maintained by the Fund in cash or cash equivalents
in a segregated account with its custodian. Each Fund may cover put options on
stock indices by maintaining liquid assets in a segregated account with its
custodian, or else by holding a put on the same
    
 
                                        7
<PAGE>   57
 
   
security and in the same principal amount as the put written where the exercise
price of the put held (a) is equal to or greater than the exercise price of the
put written or (b) is less than the exercise price of the put written if the
difference is maintained by the Fund in liquid assets in a segregated account
with its custodian. Put and call options on stock indices may also be covered in
such other manner as may be in accordance with the rules of the exchange on
which, or the counterparty with which, the option is traded and applicable laws
and regulations.
    
 
Each Fund will receive a premium from writing a put or call option on a stock
index, which increases the Fund's gross income in the event the option expires
unexercised or is closed out at a profit. If the value of an index on which a
Fund has written a call option falls or remains the same, the Fund will realize
a profit in the form of the premium received (less transaction costs) that could
offset all or a portion of any decline in the value of the securities it owns.
If the value of the index rises, however, the Fund will realize a loss in its
call option position, which will reduce the benefit of any unrealized
appreciation in the Fund's stock investments. By writing a put option, a Fund
assumes the risk of a decline in the index. To the extent that the price changes
of securities owned by a Fund correlate with changes in the value of the index,
writing covered put options on indices will increase a Fund's losses in the
event of a market decline, although such losses will be offset in part by the
premium received for writing the option.
 
Each Fund may also purchase put options on stock indices to hedge its
investments against a decline in value. By purchasing a put option on a stock
index, a Fund will seek to offset a decline in the value of securities it owns
through appreciation of the put option. If the value of the Fund's investments
does not decline as anticipated, or if the value of the option does not
increase, the Fund's loss will be limited to the premium paid for the option
plus related transaction costs. The success of this strategy will largely depend
on the accuracy of the correlation between the changes in value of the index and
the changes in value of the Fund's security holdings.
 
The purchase of call options on stock indices may be used by a Fund to attempt
to reduce the risk of missing a broad market advance, or an advance in an
industry or market segment, at a time when the Fund holds uninvested cash or
short-term debt securities awaiting investment. When purchasing call options for
this purpose, a Fund will also bear the risk of losing all or a portion of the
premium paid if the value of the index does not rise. The purchase of call
options on stock indices when a Fund is substantially fully invested is a form
of leverage, up to the amount of the premium and related transaction costs, and
involves risks of loss and of increased volatility similar to those involved in
purchasing calls on securities the Fund owns.
 
FUTURES CONTRACTS: Each Fund may enter into contracts for the purchase or sale
for future delivery of fixed income securities or foreign currencies or
contracts based on indices of securities as such instruments become available
for trading ("Futures Contracts"). This investment technique is designed to
hedge (i.e., to protect) against anticipated future changes in interest or
exchange rates which otherwise might adversely affect the value of a Fund's
portfolio securities or adversely affect the prices of long-term bonds or other
securities which a Fund intends to purchase at a later date. Futures Contracts
may also be entered into for non-hedging purposes to the extent permitted by
applicable law. A "sale" of a Futures Contract means a contractual obligation to
deliver the securities or foreign currency called for by the contract at a fixed
price at a specified time in the future. A "purchase" of a Futures Contract
means a contractual obligation to acquire the securities or foreign currency at
a fixed price at a specified time in the future.
 
While Futures Contracts provide for the delivery of securities or currencies,
such deliveries are very seldom made. Generally, a Futures Contract is
terminated by entering into an offsetting transaction. A Fund will incur
brokerage fees when it purchases and sells Futures Contracts. At the time such a
purchase or sale is made, the Fund must allocate cash or securities as a margin
deposit ("initial deposit"). It is expected that the initial deposit will vary
but may be as low as 5% or less of the value of the contract. The Futures
Contract is valued daily thereafter and the payment of "variation margin" may be
required to be paid or received, so that each day the Fund may provide or
receive cash that reflects the decline or increase in the value of the contract.
 
   
One purpose of the purchase or sale of a Futures Contract, for hedging purposes
in the case of a portfolio holding long-term debt securities, is to protect a
Fund from fluctuations in interest rates without actually buying or selling
long-term debt securities. For example, if a Fund owned long-term bonds and
interest rates were expected to increase, the Fund might enter into Futures
Contracts for the sale of debt securities. If interest rates did increase, the
value of the debt securities in the portfolio would decline, but the value of
the Fund's Futures Contracts should increase at approximately the same rate,
thereby keeping the net asset value of the Fund from declining as much as it
otherwise would have. A Fund could accomplish similar results by selling bonds
with long maturities and investing in bonds with short maturities when interest
rates are expected to increase or by buying bonds with long maturities and
selling bonds with short maturities when interest rates are expected to decline.
However, since the futures market is more liquid than the cash market, the use
of Futures Contracts as an investment technique allows a Fund to maintain a
defensive position without having to sell its portfolio securities. Transactions
entered into for non-hedging purposes have greater risk, including the risk of
losses which are not offset by gains on other portfolio assets.
    
 
Similarly, when it is expected that interest rates may decline, Futures
Contracts may be purchased to hedge against anticipated purchases of long-term
bonds at higher prices. Since
 
                                        8
<PAGE>   58
 
   
the fluctuations in the value of Futures Contracts should be similar to that of
long-term bonds, a Fund could take advantage of the anticipated rise in the
value of long-term bonds without actually buying them until the market had
stabilized. At that time, the Futures Contracts could be liquidated and the Fund
could buy long-term bonds on the cash market. Purchases of Futures Contracts
would be particularly appropriate when the cash flow from the sale of new shares
of a Fund could have the effect of diluting dividend earnings. To the extent a
Fund enters into Futures Contracts for this purpose, the assets in the
segregated asset account maintained to cover the Fund's obligations with respect
to such Futures Contracts will consist of liquid assets from the portfolio of
the Fund in an amount equal to the difference between the fluctuating market
value of such Futures Contracts and the aggregate value of the initial and
variation margin payments made by the Fund with respect to such Futures
Contracts, thereby assuring that the transactions are unleveraged.
    
 
Futures Contracts on foreign currencies may be used in a similar manner, in
order to protect against declines in the dollar value of portfolio securities
denominated in foreign currencies, or increases in the dollar value of
securities to be acquired.
 
A Futures Contract on an index of securities provides for the making and
acceptance of a cash settlement based on changes in value of the underlying
index. The index underlying a Futures Contract is a broad based index of fixed-
income securities designed to reflect movements in the relevant market as a
whole.
 
OPTIONS ON FUTURES CONTRACTS: Each Fund may write and purchase Options to buy or
sell Futures Contracts ("Options on Futures Contracts") for hedging purposes.
Each Fund may also enter into transactions in Options on Futures Contracts for
non-hedging purposes to the extent permitted by applicable law. The purchase of
a call Option on a Futures Contract is similar in some respects to the purchase
of a call option on an individual security. Depending on the pricing of the
option compared to either the price of the Futures Contract upon which it is
based or the price of the underlying debt securities, it may or may not be less
risky than ownership of the Futures Contract or underlying securities. As with
the purchase of Futures Contracts, when a Fund is not fully invested it may
purchase a call Option on a Futures Contract to hedge against a market advance
due to declining interest rates.
 
The writing of a call Option on a Futures Contract constitutes a partial hedge
against declining prices of the security underlying the Futures Contract. If the
futures price at expiration of the option is below the exercise price, a Fund
will retain the full amount of the option premium, less related transaction
costs, which provides a partial hedge against any decline that may have occurred
in the Fund's portfolio holdings. The writing of a put Option on a Futures
Contract constitutes a partial hedge against increasing prices of the security
underlying the Futures Contract. If the futures price at expiration of the
option is higher than the exercise price, the Fund will retain the full amount
of the option premium, less related transaction costs, which provides a partial
hedge against any increase in the price of securities which the Fund intends to
purchase. If a put or call option a Fund has written is exercised, the Fund will
incur a loss which will be reduced by the amount of the premium it receives.
Depending on the degree of correlation between changes in the value of its
portfolio securities and changes in the value of its futures positions, a Fund's
losses from existing Options on Futures Contracts may to some extent be reduced
or increased by changes in the value of portfolio securities.
 
Each Fund may purchase Options on Futures Contracts for hedging purposes as an
alternative to purchasing or selling the underlying Futures Contracts. For
example, where a decrease in the value of portfolio securities is anticipated as
a result of a projected market-wide decline, or a decline in the dollar value of
foreign currencies in which portfolio securities are denominated, a Fund may, in
lieu of selling Futures Contracts, purchase put options thereon. In the event
that such decrease in portfolio value occurs, it may be offset, in whole or
part, by a profit on the option. Conversely, where it is projected that the
value of securities to be acquired by a Fund will increase prior to acquisition,
due to a market advance or a rise in the dollar value of foreign currencies in
which securities to be acquired are denominated, a Fund may purchase call
Options on Futures Contracts, rather than purchasing the underlying Futures
Contracts. As in the case of Options, the writing of Options on Futures
Contracts may require a Fund to forego all or a portion of the benefits of
favorable movements in the price of portfolio securities, and the purchase of
Options on Futures Contracts may require a Fund to forego all or a portion of
such benefits up to the amount of the premium paid and related transaction
costs.
 
The amount of risk a Fund assumes when it purchases an Option on a Futures
Contract is the premium paid for the option plus related transaction costs. In
addition to the correlation risks discussed above, the purchase of an option
also entails the risk that changes in the value of the underlying Futures
Contract will not be fully reflected in the value of the option purchased.
 
A Fund's ability to engage in the options and futures strategies described above
will depend on the availability of liquid markets in such instruments. It is
impossible to predict the amount of trading interest that may exist in various
types of options or futures. Therefore, no assurance can be given that a Fund
will be able to utilize these instruments effectively for the purposes set forth
above. Furthermore, a Fund's ability to engage in options and futures
transactions may be limited by tax considerations.
 
Each Fund may cover the writing of call Options on Futures Contracts (a) through
purchases of the underlying Futures
 
                                        9
<PAGE>   59
 
   
Contract, (b) through ownership of the instrument, or instruments included in
the index, underlying the Futures Contract, or (c) through the holding of a call
on the same Futures Contract and in the same principal amount as the call
written where the exercise price of the call held (i) is equal to or less than
the exercise price of the call written or (ii) is greater than the exercise
price of the call written if the difference is maintained by the Fund in liquid
assets in a segregated account with its custodian. A Fund may cover the writing
of put Options on Futures Contracts (a) through sales of the underlying Futures
Contract, (b) through segregation of liquid assets in an amount equal to the
value of the security or index underlying the Futures Contract, or (c) through
the holding of a put on the same Futures Contract and in the same principal
amount as the put written where the exercise price of the put held is equal to
or greater than the exercise price of the put written, or is less than the
exercise price of the put written if the difference is maintained by the Fund in
liquid assets in a segregated account with its custodian. Put and call Options
on Futures Contracts may also be covered in such other manner as may be in
accordance with the rules of the exchange on which the option is traded and
applicable laws and regulations. Upon the exercise of a call Option on a Futures
Contract written by a Fund, the Fund will be required to sell the underlying
Futures Contract which, if the Fund has covered its obligation through the
purchase of such Contract, will serve to liquidate its futures position.
Similarly, where a put Option on a Futures Contract written by a Fund is
exercised, the Fund will be required to purchase the underlying Futures Contract
which, if the Fund has covered its obligation through the sale of such contract,
will close out its futures position. An Option on a Futures Contract is traded
on the same contract market as the underlying Futures Contact, subject to
regulation by the CFTC and the performance guarantee of the exchange clearing
house. Options on Futures Contracts, as noted in the Prospectus, are also traded
on foreign exchanges.
    
 
FORWARD CONTRACTS: Each Fund may enter into forward foreign currency exchange
contracts for the purchase or sale of a specific currency at a future date at a
price set at the time of the contract (a "Forward Contract"). Each Fund may also
enter into Forward Contracts for "cross-hedging" as noted in the Prospectus. A
Fund may enter into Forward Contracts for hedging purposes as well as for
non-hedging purposes. Transactions in Forward Contracts entered into for hedging
purposes will include forward purchases or sales of foreign currencies for the
purpose of protecting the dollar value of fixed income securities denominated in
a foreign currency or protecting the dollar equivalent of interest or dividends
to be paid on such securities. By entering into such transactions, however, a
Fund may be required to forego the benefits of advantageous changes in exchange
rates. Each Fund may also enter into transactions in Forward Contracts for other
than hedging purposes which presents greater profit potential but also involves
increased risk. For example, if the Adviser or the Sub-Adviser believes that the
value of a particular foreign currency will increase or decrease relative to the
value of the U.S. dollar, a Fund may purchase or sell such currency,
respectively, through a Forward Contract. If the expected changes in the value
of the currency occur, the Fund will realize profits which will increase its
gross income. Where exchange rates do not move in the direction or to the extent
anticipated, however, the Fund may sustain losses which will reduce its gross
income. Such transactions, therefore, could be considered speculative.
 
   
Each Fund has established procedures consistent with statements by the SEC and
its staff regarding the use of Forward Contracts by registered investment
companies, which require the use of segregated assets or "cover" in connection
with the purchase and sale of such contracts. In those instances in which a Fund
satisfies this requirement through segregation of assets, it will maintain, in a
segregated account, liquid assets in an amount equal to the value of its
commitments under Forward Contracts. While these contracts are not presently
regulated by the Commodity Futures Trading Commission (the "CFTC"), the CFTC may
in the future assert authority to regulate Forward Contracts. In such event, a
Fund's ability to utilize Forward Contracts in the manner set forth above may be
restricted.
    
 
OPTIONS ON FOREIGN CURRENCIES: Each Fund may purchase and write put and call
options on foreign currencies ("Options on Foreign Currencies") for the purpose
of protecting against declines in the dollar value of foreign portfolio
securities and against increases in the dollar cost of foreign securities to be
acquired. For example, a decline in the dollar value of a foreign currency in
which portfolio securities are denominated will reduce the dollar value of such
securities, even if their value in the foreign currency remains constant. In
order to protect against such diminutions in the value of portfolio securities,
a Fund may purchase put options on the foreign currency. If the value of the
currency did decline, the Fund would have the right to sell such currency for a
fixed amount in dollars and would thereby offset, in whole or in part, the
adverse effect on its portfolio which otherwise would have resulted.
 
Conversely, where a rise in the dollar value of a currency in which securities
to be acquired are denominated is projected, thereby increasing the cost of such
securities, a Fund may purchase call options thereon. The purchase of such
options could offset, at least partially, the effects of the adverse movements
in exchange rates. As in the case of other types of options, however, the
benefit to a Fund deriving from purchases of foreign currency options would be
reduced by the amount of the premium and related transaction costs. In addition,
where currency exchange rates do not move in the direction or to the extent
anticipated, a Fund could sustain losses on transactions in foreign currency
options, which would require it to forego a portion or all of the benefits of
advantageous changes in such rates.
 
                                       10
<PAGE>   60
 
Each Fund may write Options on Foreign Currencies for hedging purposes in a
manner similar to the way Forward Contracts will be utilized. For example, where
a Fund anticipates a decline in the dollar value of foreign-denominated
securities due to adverse fluctuations in exchange rates it may, instead of
purchasing a put option, write a call option on the relevant currency. If the
expected decline occurred, the option would most likely not be exercised, and
the diminution in value of portfolio securities would be offset by the amount of
the premium received less related transaction costs.
 
Similarly, instead of purchasing a call option to hedge against an anticipated
increase in the dollar cost of securities to be acquired, a Fund could write a
put option on the relevant currency which, if rates move in the manner
projected, will expire unexercised and allow the Fund to hedge such increased
cost up to the amount of the premium. As in the case of other types of options,
however, the writing of a foreign currency option will constitute only a partial
hedge up to the amount of the premium, less transaction costs, and only if rates
move in the expected direction. If this does not occur, the option may be
exercised and the Fund would be required to purchase or sell the underlying
currency at a loss which may not be offset by the amount of the premium. Through
the writing of Options on Foreign Currencies, a Fund also may be required to
forego all or a portion of the benefits which might otherwise have been obtained
from favorable movements in exchange rates.
 
   
All call and put options written on foreign currencies will be covered. A call
option written on foreign currencies by a Fund is "covered" if the Fund owns the
underlying foreign currency covered by the call or has an absolute and immediate
right to acquire that foreign currency without additional cash consideration (or
for additional cash consideration held in a segregated account by its custodian)
upon conversion or exchange of other foreign currency held in its portfolio. A
call option is also covered if a Fund has a call on the same foreign currency
and in the same principal amount as the call written where the exercise price of
the call held (a) is equal to or less than the exercise price of the call
written or (b) is greater than the exercise price of the call written if the
difference is maintained by the Fund in liquid assets in a segregated account
with its custodian. A put option written by a Fund is "covered" if the Fund
maintains liquid assets in a segregated account with its custodian, or else
holds a put on the same security and in the same principal amount as the put
written where the exercise price of the put held (a) is equal to or greater than
the exercise price of the put written or (b) is less than the exercise price of
the put written if the difference is maintained by the Fund in liquid assets in
a segregated account with its custodian. Call and put options on foreign
currencies may also be covered in such other manner as may be in accordance with
the requirements of the exchange on which, or the counterparty with which, the
option is traded and applicable rules and regulations.
    
 
ADDITIONAL RISKS OF INVESTING IN OPTIONS ON SECURITIES, OPTIONS ON STOCK
INDICES, FUTURES CONTRACTS, OPTIONS ON FUTURES CONTRACTS, FORWARD CONTRACTS AND
OPTIONS ON FOREIGN CURRENCIES: Unlike transactions entered into by a Fund in
Futures Contracts, Options on Foreign Currencies and Forward Contracts are not
traded on contract markets regulated by the CFTC or (with the exception of
certain foreign currency options) by the SEC. To the contrary, such instruments
are traded through financial institutions acting as market-makers, although
foreign currency options are also traded on certain national securities
exchanges, such as the Philadelphia Stock Exchange and the Chicago Board Options
Exchange, subject to SEC regulation. Similarly, options on securities and on
stock indices may be traded over-the-counter. In an over-the-counter trading
environment, many of the protections afforded to exchange participants will not
be available. For example, there are no daily price fluctuation limits, and
adverse market movements could therefore continue to an unlimited extent over a
period of time. Although the purchaser of an option cannot lose more than the
amount of the premium plus related transaction costs, this entire amount could
be lost. Moreover, the option writer and a trader of Forward Contracts could
lose amounts substantially in excess of their initial investments, due to the
margin and collateral requirements associated with such positions.
 
A Fund's ability effectively to hedge all or a portion of its portfolio through
transactions in options, Futures Contracts, and Forward Contracts will depend on
the degree to which price movements in the underlying instruments correlate with
price movements in the relevant portion of the Fund's portfolio. If the values
of fixed income portfolio securities being hedged do not move in the same amount
or direction as the instruments underlying options, Futures Contracts or Forward
Contracts traded, a Fund's hedging strategy may not be successful and the Fund
could sustain losses on its hedging strategy which would not be offset by gains
on its portfolio. It is also possible that there may be a negative correlation
between the instrument underlying an Option, Futures Contract or Forward
Contract traded and the portfolio securities being hedged, which could result in
losses both on the hedging transaction and the portfolio securities. In such
instances, a Fund's overall return could be less than if the hedging transaction
had not been undertaken. In the case of futures and Options on fixed income
securities, the portfolio securities which are being hedged may not be the same
type of obligation underlying such contract. As a result, the correlation
probably will not be exact. Consequently, a Fund bears the risk that the price
of the fixed income portfolio securities being hedged will not move in the same
amount or direction as the underlying index or obligation. Where a Fund enters
into Forward Contracts as a "cross hedge" (i.e., the purchase or sale of a
Forward Contract on one currency to hedge against risk of loss arising from
changes in value of a second currency), the Fund incurs the risk of imperfect
correlation between
 
                                       11
<PAGE>   61
 
changes in the values of the two currencies, which could result in losses.
 
The correlation between prices of securities and prices of Options, Futures
Contracts or Forward Contracts may be distorted due to differences in the nature
of the markets, such as differences in margin requirements, the liquidity of
such markets and the participation of speculators in the Option, Futures
Contract and Forward Contract markets. The trading of Options on Futures
Contracts also entails the risk that changes in the value of the underlying
Futures Contract will not be fully reflected in the value of the option. The
risk of imperfect correlation, however, generally tends to diminish as the
maturity or termination date of the Option, Futures Contract or Forward Contract
approaches.
 
The trading of Options, Futures Contracts and Forward Contracts also entails the
risk that, if the Adviser's or the Sub-Adviser's judgment as to the general
direction of exchange rates is incorrect, a Fund's overall performance may be
poorer than if it had not entered into any such contract.
 
It should be noted that each Fund may purchase and write Options, Futures
Contracts, Options on Futures Contracts and Forward Contracts not only for
hedging purposes, but also for non-hedging purposes to the extent permitted by
applicable law for the purpose of increasing its return. As a result, a Fund
will incur the risk that losses on such transactions will not be offset by
corresponding increases in the value of portfolio securities or decreases in the
cost of securities to be acquired.
 
     POTENTIAL LACK OF A LIQUID SECONDARY MARKET -- Prior to exercise or
expiration, a position in an exchange-traded Option, Futures Contract, Option on
a Futures Contract or Option on a Foreign Currency can only be terminated by
entering into a closing purchase or sale transaction, which requires a secondary
market for such instruments on the exchange on which the initial transaction was
entered into. If no such market exists, it may not be possible to close out a
position, and a Fund could be required to purchase or sell the underlying
instrument or meet ongoing variation margin requirements. The inability to close
out option or futures positions also could have an adverse effect on a Fund's
ability effectively to hedge its portfolio.
 
The liquidity of a secondary market in an Option or Futures Contract may be
adversely affected by "daily price fluctuation limits," established by the
exchanges, which limit the amount of fluctuation in the price of a contract
during a single trading day and prohibit trading beyond such limits once they
have been reached. Such limits could prevent a Fund from liquidating open
positions, which could render its hedging strategy unsuccessful and result in
trading losses. The exchanges on which Options and Futures Contracts are traded
have also established a number of limitations governing the maximum number of
positions which may be traded by a trader, whether acting alone or in concert
with others. Further, the purchase and sale of exchange-traded Options and
Futures Contracts is subject to the risk of trading halts, suspensions, exchange
or clearing corporation equipment failures, government intervention, insolvency
of a brokerage firm, intervening broker or clearing corporation or other
disruptions of normal trading activity, which could make it difficult or
impossible to liquidate existing positions or to recover excess variation margin
payments.
 
     OPTIONS ON FUTURES CONTRACTS -- In order to profit from the purchase of an
Option on a Futures Contract, it may be necessary to exercise the option and
liquidate the underlying Futures Contract, subject to all of the risks of
futures trading. The writer of an Option on a Futures Contract is subject to the
risks of futures trading, including the requirement of initial and variation
margin deposits.
 
ADDITIONAL RISKS OF TRANSACTIONS RELATED TO FOREIGN CURRENCIES AND TRANSACTIONS
NOT CONDUCTED ON U.S. EXCHANGES: The available information on which a Fund will
make trading decisions concerning transactions related to foreign currencies or
foreign securities may not be as complete as the comparable data on which a Fund
makes investment and trading decisions in connection with other transactions.
Moreover, because the foreign currency market is a global, 24-hour market, and
the markets for foreign securities as well as markets in foreign countries may
be operating during non-business hours in the U.S., events could occur in such
markets which would not be reflected until the following day, thereby rendering
it more difficult for a Fund to respond in a timely manner.
 
In addition, over-the-counter transactions can only be entered into with a
financial institution willing to take the opposite side, as principal, of a
Fund's position, unless the institution acts as broker and is able to find
another counterparty willing to enter into the transaction with the Fund. This
could make it difficult or impossible to enter into a desired transaction or
liquidate open positions, and could therefore result in trading losses. Further,
over-the-counter transactions are not subject to the performance guarantee of an
exchange clearing house and a Fund will therefore be subject to the risk of
default by, or the bankruptcy of, a financial institution or other counterparty.
 
Transactions on exchanges located in foreign countries may not be conducted in
the same manner as those entered into on U.S. exchanges, and may be subject to
different margin, exercise, settlement or expiration procedures.
 
As a result, many of the risks of over-the-counter trading may be present in
connection with such transactions. Moreover, the SEC or CFTC has jurisdiction
over the trading in the U.S. of many types of over-the-counter and foreign
instruments, and such agencies could adopt regulations or interpretations which
would make it difficult or impossible for a Fund to enter into the trading
strategies identified herein or to liquidate existing positions.
 
As a result of its investments in foreign securities, a Fund may receive
interest or dividend payments, or the proceeds
 
                                       12
<PAGE>   62
 
of the sale or redemption of such securities, in the foreign currencies in which
such securities are denominated. A Fund may also be required to receive delivery
of the foreign currencies underlying Options on Foreign Currencies or Forward
Contracts it has entered into. This could occur, for example, if an option
written by a Fund is exercised or the Fund is unable to close out a Forward
Contract it has entered into. In addition, the Fund may elect to take delivery
of such currencies. Under certain circumstances, such as where the Adviser or
the Sub-Adviser believes that the applicable exchange rate is unfavorable at the
time the currencies are received or the Adviser or the Sub-Adviser anticipates,
for any other reason, that the exchange rate will improve, a Fund may hold such
currencies for an indefinite period of time. While the holding of currencies
will permit a Fund to take advantage of favorable movements in the applicable
exchange rate, such strategy also exposes the Fund to risk of loss if exchange
rates move in a direction adverse to the Fund's position. Such losses could
reduce any profits or increase any losses sustained by a Fund from the sale or
redemption of securities and could reduce the dollar value of interest or
dividend payments received.
 
RESTRICTIONS ON THE USE OF OPTIONS AND FUTURES: In order to assure that each
Fund will not be deemed to be a "commodity pool" for purposes of the Commodity
Exchange Act, regulations of the CFTC require that a Fund enter into
transactions in Futures Contracts and Options on Futures Contracts only (i) for
bona fide hedging purposes (as defined in CFTC regulations), or (ii) for
non-hedging purposes, provided that the aggregate initial margin and premiums on
such non-hedging positions does not exceed 5% of the liquidation value of each
Fund's assets. In addition, each Fund must comply with the requirements of
various state securities laws in connection with such transactions.
 
Each Fund has adopted the additional restriction that it will not enter into a
Futures Contract if, immediately thereafter, the value of securities and other
obligations underlying all such Futures Contracts would exceed 50% of the value
of the Fund's total assets. Moreover, each Fund will not purchase put and call
Options if, as a result, more than 5% of its total assets would be invested in
such Options.
 
When each Fund purchases a Futures Contract, an amount of cash and cash
equivalents will be deposited in a segregated account with the Fund's custodian
so that the amount so segregated will at all times equal the value of the
Futures Contract, thereby ensuring that the leveraging effect of such Futures
Contract is minimized.
 
INDEXED SECURITIES: Each Fund may purchase securities whose prices are indexed
to the prices of other securities, indices, currencies, or other financial
indicators. Indexed securities typically, but not always, are debt securities or
deposits whose value at maturity (i.e., principal value) or coupon rate is
determined by reference to a specific instrument or statistic. Currency-indexed
securities typically are short-term to intermediate-term debt securities whose
maturity values or interest rates are determined by reference to the values of
one or more specified foreign currencies, and may offer higher yields than U.S.
dollar-denominated securities of equivalent issuers. Currency-indexed securities
may be positively or negatively indexed; that is, their maturity value may
increase when the specified currency value increases, resulting in a security
that performs similarly to a foreign-denominated instrument, or their maturity
value may decline when foreign currencies increase, resulting in a security
whose price characteristics are similar to a put on the underlying currency.
Currency-indexed securities may also have prices that depend on the values of a
number of different foreign currencies relative to each other.
 
The performance of indexed securities depends to a great extent on the
performance of the security, currency, or other instrument to which they are
indexed, and may also be influenced by interest rate changes in the U.S. and
abroad. At the same time, indexed securities are subject to the credit risks
associated with the issuer of the security, and their value may decline
substantially if the issuer's creditworthiness deteriorates.
 
SWAPS AND RELATED TRANSACTIONS: Each Fund may enter into interest rate swaps,
currency swaps and other types of available swap agreements, such as caps,
collars and floors.
 
Swap agreements may be individually negotiated and structured to include
exposure to a variety of different types of investments or market factors.
Depending on their structure, swap agreements may increase or decrease a Fund's
exposure to long or short-term interest rates (in the U.S. or abroad), foreign
currency values, mortgage securities, corporate borrowing rates, or other
factors such as securities prices or inflation rates. Swap agreements can take
many different forms and are known by a variety of names. A Fund is not limited
to any particular form or variety of swap agreement if MFS determines it is
consistent with the Fund's investment objective and policies.
 
Each Fund will maintain cash or appropriate liquid assets with its custodian to
cover its current obligations under swap transactions. If a Fund enters into a
swap agreement on a net basis (i.e., the two payment streams are netted out,
with the Fund receiving or paying, as the case may be, only the net amount of
the two payments), the Fund will maintain cash or liquid assets with its
custodian with a daily value at least equal to the excess, if any, of the Fund's
accrued obligations under the swap agreement over the accrued amount of the Fund
is entitled to receive under the agreement. If a Fund enters into a swap
agreement on other than a net basis, it will maintain cash or liquid assets with
a value equal to the full amount of the Fund's accrued obligations under the
agreement.
 
The most significant factor in the performance of swaps, caps, floors and
collars is the change in the specific interest rate, currency or other factor
that determines the amount of payments to be made under the arrangement. If the
Adviser or the Sub-Adviser is incorrect in its forecasts of such
 
                                       13
<PAGE>   63
 
factors, the investment performance of a Fund would be less than what it would
have been if these investment techniques had not been used. If a swap agreement
calls for payments by a Fund, the Fund must be prepared to make such payments
when due. In addition, if the counter-party's creditworthiness declined, the
value of the swap agreement would be likely to decline, potentially resulting in
losses. If the counterparty defaults, a Fund's risk of loss consists of the net
amount of payments that the Fund is contractually entitled to receive. Each Fund
anticipates that it will be able to eliminate or reduce its exposure under these
arrangements by assignment or other disposition or by entering into an
offsetting agreement with the same or another counterparty.

                      ------------------------------------
 
The policies stated above are not fundamental and may be changed without
shareholder approval, as may each Fund's investment objective.
 
INVESTMENT RESTRICTIONS: Each Fund has adopted the following restrictions which
cannot be changed without the approval of the holders of a majority of the
Fund's shares (which, as used in this SAI, means the lesser of (i) more than 50%
of the outstanding shares of the Trust or a Fund or class, as applicable, or
(ii) 67% or more of the outstanding shares of the Trust or a Fund or class, as
applicable, present at a meeting at which holders of more than 50% of the
outstanding shares of the Trust or a Fund or class, as applicable, are
represented in person or by proxy):
 
Each Fund may not:
 
    (1) borrow amounts in excess of 33 1/3% of its assets including amounts
  borrowed;
 
    (2) underwrite securities issued by other persons except insofar as the Fund
  may technically be deemed an underwriter under the Securities Act of 1933 in
  selling a portfolio security;
 
    (3) purchase or sell real estate (including limited partnership interests
  but excluding securities secured by real estate or interests therein and
  securities of companies, such as real estate investment trusts, which deal in
  real estate or interests therein), interests in oil, gas or mineral leases,
  commodities or commodity contracts (excluding Options, Options on Futures
  Contracts, Options on Stock Indices, Options on Foreign Currency and any other
  type of option, Futures Contracts, any other type of futures contract, and
  Forward Contracts) in the ordinary course of its business. The Fund reserves
  the freedom of action to hold and to sell real estate, mineral leases,
  commodities or commodity contracts (including Options, Options on Futures
  Contracts, Options on Stock Indices, Options on Foreign Currency and any other
  type of option, Futures Contracts, any other type of futures contract, and
  Forward Contracts) acquired as a result of the ownership of securities;
 
    (4) issue any senior securities except as permitted by the 1940 Act. For
  purposes of this restriction, collateral arrangements with respect to any type
  of option (including Options on Futures Contracts, Options, Options on Stock
  Indices and Options on Foreign Currencies), any type of swap agreement,
  Forward Contracts, Futures Contracts, any other type of futures contract, and
  collateral arrangements with respect to initial and variation margin are not
  deemed to be the issuance of a senior security;
 
    (5) make loans to other persons. For these purposes, the purchase of
  short-term commercial paper, the purchase of a portion or all of an issue of
  debt securities, the lending of portfolio securities, or the investment of the
  Fund's assets in repurchase agreements, shall not be considered the making of
  a loan; or
 
    (6) purchase any securities of an issuer of a particular industry, if as a
  result, more than 25% of its assets would be invested in securities of issuers
  whose principal business activities are in the same industry (except
  obligations issued or guaranteed by the U.S. Government or its agencies and
  instrumentalities and repurchase agreements collateralized by such
  obligations).
 
In addition, each Fund has the following nonfundamental policies which may be
changed without shareholder approval. Each Fund will not:
 
   
    (1) invest in illiquid investments, including securities subject to legal or
  contractual restrictions on resale or for which there is no readily available
  market (e.g., trading in the security is suspended, or, in the case of
  unlisted securities, where no market exists), if more than 15% of the Fund's
  net assets (taken at market value) would be invested in such securities.
  Repurchase agreements maturing in more than seven days will be deemed to be
  illiquid for purposes of the Fund's limitation on investment in illiquid
  securities. Securities that are not registered under the Securities Act of
  1933, as amended, and sold in reliance on Rule 144A thereunder, but are
  determined to be liquid by the Trust's Board of Trustees (or its delegee),
  will not be subject to this 15% limitation;
    
 
    (2) invest more than 10% of the value of the Fund's net assets, valued at
  the lower of cost or market, in warrants. Included within such amount may be
  warrants which are not listed on the New York or American Stock Exchange.
  Warrants acquired by the Fund in units or attached to securities may be deemed
  to be without value;
 
    (3) invest for the purpose of exercising control or management;
 
   
    (4) purchase securities issued by any other investment company in excess of
  the amount permitted by the 1940 Act, except when such purchase is part of a
  plan of merger or consolidation;
 
    (5) purchase or retain securities of an issuer any of whose officers,
  directors, trustees or security holders is an
    
 
                                       14
<PAGE>   64
 
  officer or Trustee of the Fund, or is an officer or a director of the
  investment adviser or a sub-adviser of the Fund, if one or more of such
  persons also owns beneficially more than 0.5% of the securities of such
  issuer, and such persons owning more than 0.5% of such securities together own
  beneficially more than 5% of such securities;
 
    (6) purchase any securities or evidences of interest therein on margin,
  except that the Fund may obtain such short-term credit as may be necessary for
  the clearance of any transaction and except that the Fund may make margin
  deposits in connection with any type of option (including Options on Futures
  Contracts, Options, Options on Stock Indices and Options on Foreign
  Currencies), any type of swap agreement, any type of futures contract
  (including Futures Contracts) and Forward Contracts;
 
    (7) sell any security which the Fund does not own unless by virtue of its
  ownership of other securities the Fund has at the time of sale a right to
  obtain securities without payment of further consideration equivalent in kind
  and amount to the securities sold and provided that if such right is
  conditional, the sale is made upon the same conditions;
 
    (8) invest more than 5% of its gross assets in companies which, including
  predecessors, controlling persons, sponsoring entities, general partners and

* "Interested persons" (as defined in the 1940 Act) of the Adviser, whose
  address is 500 Boylston Street, Boston, Massachusetts 02116.
 
Each Trustee and officer holds comparable positions with certain affiliates of
MFS or with certain other funds of which MFS or a subsidiary is the investment
adviser or distributor. Mr. Brodkin, the Chairman of MFD, Messrs. Shames and
Scott, Directors of MFD, and Mr. Cavan, the Secretary of MFD, hold similar
positions with certain other MFS affiliates. Mr. Bailey is a Director of Sun
Life Assurance Company of Canada (U.S.) ("Sun Life of Canada (U.S.)"), the
corporate parent of MFS.
 
Each Fund pays the compensation of the non-interested Trustees and Mr. Bailey
(who currently receive a fee per Fund of $250 per year plus $25 per meeting and
$20 per committee meeting attended, together with such Trustee's out-of-pocket
expenses), and have adopted a retirement plan for non-interested Trustees and
Mr. Bailey. Under this plan, a Trustee will retire upon reaching age 73 and if
the Trustee has completed at least 5 years of service, he would be entitled to
annual payments during his lifetime of up to 50% of such Trustee's average
annual compensation (based on the three years prior to his retirement) depending
on his length of service. A Trustee may also retire prior to age 73 and receive
reduced payments if he has completed at least 5 years of service. Under the
plan, a Trustee (or his beneficiaries) will also receive benefits for a period
of time in the event the Trustee is disabled or dies. These benefits will also
be based on the Trustee's average annual compensation and length of service.
There is no retirement plan provided by the Trust for Messrs. Brodkin, Scott and
Shames. Each Fund will accrue its allocable portion of compensation expenses
under the retirement plan each year to cover the current year's service and
amortize past service cost.
 
   
Set forth below is certain information concerning the cash compensation
estimated to be paid by each Fund to the Trustees, and benefits accrued and
estimated benefits payable, under the retirement plan.

The Declaration of Trust provides that the Trust will indemnify its Trustees and
officers against liabilities and expenses incurred in connection with litigation
in which they may be involved because of their offices with the Trust, unless as
to liability to the Trust or its shareholders, it is determined that they
engaged in willful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in their offices, or with respect to any
matter, unless it is adjudicated that they did not act in good faith in the
reasonable belief that their actions were in the best interests of the Trust. In
the case of settlement, such indemnification will not be provided unless it has
been determined pursuant to the Trust's Declaration of Trust that they have not
engaged in willful misfeasance, bad faith, gross negligence or reckless
disregard of their duties.

compliance, shareholder communications and other administrative services
pursuant to a Master Administrative Services Agreement dated March 1, 1997.
Under this Agreement, the Fund pays MFS an administrative fee up to 0.015% per

portion of the costs it incurs to provide such services.
 
INVESTMENT ADVISORY AGREEMENTS -- The Adviser manages each Fund pursuant to
separate Investment Advisory Agreements, each dated as of September 1, 1995 (the
"Advisory Agreements"). Under the Advisory Agreements, the Adviser provides each

$313,570, $103,167 and $182,020 (equivalent on an annualized basis to 0.975%,
0.975% and 1.25%, respectively, of each of the Fund's average daily net assets)

International Growth Fund, International Growth and Income Fund and Emerging
Markets Equity Fund, respectively.
 
The Adviser pays the compensation of the Trust's officers and of any Trustee who
is an officer of the Adviser. The Adviser also furnishes at its own expense all
necessary administrative services, including office space, equipment, clerical
personnel, investment advisory facilities, and all executive and supervisory
personnel necessary for managing each Fund's investments, effecting its
portfolio transactions, and, in general, administering its affairs.
 
The Advisory Agreement with each Fund will remain in effect until August 1, 1998
and will continue in effect thereafter only if such continuance is specifically
approved at least annually by the Board of Trustees or by vote of a majority of
the Fund's shares (as defined in "Investment Policies and Restrictions") and, in
either case, by a majority of the Trustees who are not parties to the Advisory
Agreement or interested persons of any such party. Each Advisory Agreement
terminates automatically if it is assigned and may be terminated without penalty
by vote of a majority of the Fund's shares (as defined in "Investment Policies
and Restrictions"), or by either party on not more than 60 days' nor less than
30 days' written notice. Each Advisory Agreement provides that if MFS ceases to

initials "MFS" and that MFS may render services to others and may permit other
fund clients to use the initials "MFS" in their names. Each Advisory Agreement
also provides that neither the Adviser nor its personnel shall be liable for any
error of judgment or mistake of law or for any loss arising out of any
investment or for any act or omission in the execution and management of the
Fund, except for willful misfeasance, bad faith or gross negligence in the
performance of its or their duties or by reason of reckless disregard of its or
their obligations and duties under the Advisory Agreement.
 
   
FCM -- FCM serves as each Fund's sub-adviser pursuant to separate Sub-Advisory
Agreements, each dated September 1, 1995 between the Adviser and FCM (the "FCM
Sub-Advisory Agreements"). Each FCM Sub-Advisory Agreement provides that the
Adviser may delegate to FCM the authority to make investment decisions for the
Fund. It is presently intended that FCM will provide portfolio management
services for each Fund. For these services, the Adviser pays FCM an annual fee
computed and paid monthly in an amount equal to 0.80% and 1.00% of the average
daily net assets of the International Growth Fund and the Emerging Markets
Equity Fund, respectively, and 0.75% of the average daily net assets managed by
FCM of the International Growth and Income Fund.
    
 
FCEM -- FCEM serves as each Fund's sub-adviser pursuant to separate Sub-Advisory
Agreements, each dated September 1, 1995 between FCM and FCEM (the "FCEM
Sub-Advisory Agreements" and together with the FCM Sub-Advisory Agreements, the
"Sub-Advisory Agreements"). Each FCEM Sub-Advisory Agreement provides that FCM
may delegate to FCEM the authority to make investment decisions for the Fund. It
is presently intended that FCEM will provide portfolio management services for
the portion of the assets of the Funds invested in emerging markets securities.
For these services, FCM pays FCEM an annual fee computed and paid monthly in an
amount equal to 1.00% of the average daily net assets managed by FCEM of each
Fund.
 
   
SUB-ADVISORY AGREEMENTS -- Each Sub-Advisory Agreement will remain in effect
until August 1, 1998, and will continue in effect thereafter only if such
continuance is specifically approved at least annually by the Board of Trustees
or by the vote of a majority of the relevant Fund's outstanding shares, and, in
either case, by a majority of the Trustees who are not parties to the
Sub-Advisory Agreement or interested persons of any such party. Each FCM Sub-
Advisory Agreement terminates automatically if it is assigned and may be
terminated without penalty by the Trustees, by vote of a majority of the
relevant Fund's outstanding shares, by the Adviser on not less than 30 days' nor
more than 60 days' written notice or by FCM, on not less than 60 days' nor more
than 90 days' written notice. Each FCEM Sub-Advisory Agreement terminates
automatically if it is assigned and may be terminated without penalty by the
Trustees, by vote of a majority of the relevant Fund's outstanding shares, by
the Adviser or FCM on not less than 30 days' nor more than 60 days' written
notice or by FCEM on not less than 60 days' nor more than 90 days' written
notice.
    
 
Each FCM Sub-Advisory Agreement provides that if FCM ceases to serve as the
sub-adviser to the Fund, the Fund will change its name so as to delete the words
"Foreign & Colonial" and that FCM may render services to others and may permit
other fund clients to use the words "Foreign & Colonial" in their names. Each
Sub-Advisory Agreement specifically provides that neither FCM or FCEM, as the
case may be, nor its personnel shall be liable for any error of judgment or
mistake of law or for any loss arising out of any investment or for any act or
omission in the execution and management of the relevant Fund, except for
willful misfeasance, bad faith or gross negligence in the performance of its or
their duties or by reason of reckless disregard of its or their obligations and
duties under the Sub-Advisory Agreement.
 
   
For the period from commencement of investment operations, October 24, 1995, to
May 31, 1996, the Adviser paid the Sub-Adviser fees under the Sub-Advisory
Agreements of $255,468, $59,933 and $144,524 in connection with its services for

$165,930 and $546,167 in connection with its services for International Growth
Fund, International Growth and Income Fund and Emerging Markets Equity Fund,

CUSTODIAN
 
State Street Bank and Trust Company (the "Custodian") is the custodian of each
Fund's assets. The Custodian's responsibilities include safekeeping and
controlling each Fund's cash and securities, handling the receipt and delivery
of securities, determining income and collecting interest and dividends on each
Fund's investments, maintaining books of original entry for portfolio and fund
accounting and other required books and accounts, and calculating the daily net
asset value of each class of shares of each Fund. The Custodian does not
determine the investment policies of each Fund or decide which securities each
Fund will buy or sell. Each Fund may, however, invest in securities of the
Custodian and may deal with the Custodian as principal in securities
transactions. The Custodian also acts as the dividend disbursing agent of each
Fund. The Custodian has contracted with the Adviser for the Adviser to perform
certain accounting functions related to options transactions for which the
Adviser receives remuneration on a cost basis.
 
SHAREHOLDER SERVICING AGENT
 
MFS Service Center, Inc. (the "Shareholder Servicing Agent"), a wholly owned
subsidiary of MFS, is each Fund's
 
                                       21
<PAGE>   71
 
   
shareholder servicing agent, pursuant to a Shareholder Servicing Agreement dated
December 19, 1985, as modified, (the "Agency Agreement") with the Trust. The
Shareholder Servicing Agent's responsibilities under the Agency Agreement
include administering and performing transfer agent functions and the keeping of
records in connection with the issuance, transfer and redemption of each class
of shares of each Fund. For these services, the Shareholder Servicing Agent will
receive a fee calculated as a percentage of the average daily net assets of each
Fund at an effective annual rate of 0.13%. In addition, the Shareholder
Servicing Agent will be reimbursed by each Fund for certain expenses incurred by
the Shareholder Servicing Agent on behalf of the Fund. State Street Bank and
Trust Company, the dividend and distribution disbursing agent of each Fund, has
contracted with the Shareholder Servicing Agent to perform certain dividend and
distribution disbursing functions for the Fund.
    
 
DISTRIBUTOR
 
MFD, a wholly owned subsidiary of MFS, serves as distributor for the continuous
offering of shares of each Fund pursuant to a Distribution Agreement with the
Trust dated as of September 1, 1995.
 
CLASS A SHARES: MFD acts as agent in selling Class A shares of each Fund to
dealers. The public offering price of Class A shares of each Fund is their net
asset value next computed after the sale plus a sales charge which varies based
upon the quantity purchased. The public offering price of a Class A share of
each Fund is calculated by dividing the net asset value of a Class A share by
the difference (expressed as a decimal) between 100% and the sales charge
percentage of offering price applicable to the purchase (see "Purchases" in the
Prospectus). The sales charge scale set forth in the Prospectus applies to
purchases of Class A shares of each Fund alone or in combination with shares of
all classes of certain other funds in the MFS Family of Funds (the "MFS Funds")
and other funds (as noted under Right of Accumulation) by any person, including
members of a family unit (e.g., husband, wife and minor children) and bona fide
trustees, and also applies to purchases made under the Right of Accumulation or
a Letter of Intent (see "Investment and Withdrawal Programs" below). A group
might qualify to obtain quantity sales charge discounts (see "Investment and
Withdrawal Programs" in this SAI).
 
Class A shares of each Fund may be sold at their net asset value to certain
persons and in certain instances, as described in the Prospectus. Such sales are
made without a sales charge to promote good will with employees and others with
whom MFS, MFD and/or a Fund have business relationships, and because the sales
effort, if any, involved in making such sales is negligible.
 
MFD allows discounts to dealers (which are alike for all dealers) from the
applicable public offering price of the Class A shares. Dealer allowances
expressed as a percentage of offering price for all offering prices are set
forth in the Prospectus (see "Purchases" in the Prospectus). The difference
between the total amount invested and the sum of (a) the net proceeds to a Fund
and (b) the dealer commission, is the commission paid to the distributor.
Because of rounding in the computation of offering price, the portion of the
sales charge paid to the distributor may vary and the total sales charge may be
more or less than the sales charge calculated using the sales charge expressed
as a percentage of the offering price or as a percentage of the net amount
invested as listed in the Prospectus. In the case of the maximum sales charge,
the dealer retains 4.00% and MFD retains approximately 3/4 of 1% of the public
offering price. MFD, on behalf of each Fund, pays a commission to dealers who
initiate and are responsible for purchases of $1 million or more as described in
the Prospectus.
 
   
CLASS B SHARES AND CLASS C SHARES: MFD acts as agent in selling Class B shares,
Class C shares and Class I shares of each Fund. The public offering price of
Class B, Class C and Class I shares is their net asset value next computed after
the sale (see "Purchases" in the Prospectus and the Prospectus Supplement to
which Class I shares are offered).
    
 
GENERAL: Neither MFD nor dealers are permitted to delay placing orders to
benefit themselves by a price change. On occasion, MFD may obtain brokers loans
from various banks, including the custodian banks for the MFS Funds, to
facilitate the settlement of sales of shares of a Fund to dealers. MFD may
benefit from its temporary holding of funds paid to it by investment dealers for
the purchase of Fund shares.
 
   
During the period from the commencement of operations, October 24, 1995, to May
31, 1996 and the fiscal year ended May 31, 1997, for the International Growth
Fund, MFD and dealers and certain other financial institutions received sales
charges of $66,057 and $685,593, and $79,525 and $437,735, respectively, (as
their concession on gross sales charges of $751,650 and $517,260, respectively)
for selling Class A shares. The International Growth Fund received $24,853,732
and $19,720,949, respectively, representing the aggregate net asset value of
such shares.

for selling Class A shares. The Emerging Markets Equity Fund received
$11,518,725 and $11,227,785, respectively, representing the aggregate net asset
value of such shares.

the International Growth Fund was $1,254. During the fiscal year ended May 31,
1997, the CDSC paid on Class A shares for the International Growth and Income
Fund was $11. During the fiscal year ended May 31, 1997, the CDSC paid on Class
A shares for the Emerging Growth Fund was $48. During the period from the
commencement of operations, October 24, 1995, to May 31, 1996 and the fiscal
year ended May 31, 1997, the CDSC paid on Class B shares for the International
Growth Fund was $9,530 and $103,091, respectively. During the period from the
commencement of operations, October 24, 1995, to May 31, 1996 and the fiscal
year ended May 31, 1997, the CDSC paid on Class B shares for the International
Growth and Income Fund was $7,513 and $32,134, respectively. During the period
from the commencement of operations, October 24, 1995, to May 31, 1996 and the
fiscal year ended May 31, 1997, the CDSC paid on Class B shares for the Emerging

Fund was $3,733. During the fiscal year ended May 31, 1997, the CDSC paid on
Class C shares for the International Growth and Income Fund was $213. During the
fiscal year ended May 31, 1997, the CDSC paid on Class C shares for the Emerging
Growth Fund was $1,252. During the period from the commencement of operations,
October 24, 1995 to May 31, 1996, there were no CDSC paid on Class A shares for
any of these Funds.
 
The Distribution Agreement will remain in effect until September 1, 1998 and
will continue in effect thereafter only if such continuance is specifically
approved at least annually by the Board of Trustees or by vote of a majority of
the Trust's shares (as defined in "Investment Policies and
Restrictions -- Investment Restrictions") and in either case, by a majority of
the Trustees who are not parties to the Distribution Agreement or interested
persons of any such party. The Distribution Agreement terminates automatically
if it is assigned and may be terminated without penalty by either party on not
more than 60 days' nor less than 30 days' notice.
    
 
4. PORTFOLIO TRANSACTIONS AND BROKERAGE COMMISSIONS
 
Specific decisions to purchase or sell securities for the Funds are made by
persons affiliated with the Adviser or the Sub-Adviser. Any such person may
serve other clients of the Adviser or the Sub-Adviser, or any subsidiary of the
Adviser or the Sub-Adviser in a similar capacity. Changes in each Fund's
investments are reviewed by the Board of Trustees.
 
The primary consideration in placing portfolio security transactions is
execution at the most favorable prices. The Adviser or the Sub-Adviser has
complete freedom as to the markets in and broker-dealers through which it seeks
this result. In the U.S. and in some other countries debt securities are traded
principally in the over-the-counter market on a net basis through dealers acting
for their own account and not as brokers. In other countries both debt and
equity securities are traded on exchanges at fixed commission rates. The cost of
securities purchased from underwriters includes an underwriter's commission or
concession, and the prices at which securities are purchased and sold from and
to dealers include a dealer's mark-up or mark-down. The Adviser or the
Sub-Adviser normally seeks to deal directly with the primary market makers or on
major exchanges unless, in its opinion, better prices are available elsewhere.
Subject to the requirement of seeking execution at the best available price,
securities may, as authorized by an Advisory Agreement or a Sub-Advisory
Agreement, be bought from or sold to dealers who have furnished statistical,
research and other information or services to the Adviser or the Sub-Adviser. At
present no arrangements for the recapture of commission payments are in effect.
 
   
Consistent with the foregoing primary consideration, the Conduct Rules of the
National Association of Securities Dealers (the "NASD") and such other policies
as the Trustees may determine, the Adviser or the Sub-Adviser may consider sales
of shares of a Fund and of the other investment company clients of MFD as a
factor in the selection of broker-dealers to execute the Fund's portfolio
transactions.
    
 
Under an Advisory Agreement or a Sub-Advisory Agreement and as permitted by
Section 28(e) of the Securities Exchange Act of 1934, the Adviser may cause a
Fund to pay a broker-dealer which provides brokerage and research services to
the Adviser or the Sub-Adviser, an amount of commission for effecting a
securities transaction for the Fund in excess of the amount other broker-dealers
would have charged for the transaction, if the Adviser or the Sub-Adviser
determines in good faith that the greater commission is reasonable in relation
to the value of the brokerage and research services provided by the executing
broker-dealer viewed in terms of either a particular transaction or their
respective overall responsibilities to the Fund or to their other clients. Not
all of such services are useful or of value in advising a Fund.
 
The term "brokerage and research services" includes advice as to the value of
securities, the advisability of investing in, purchasing or selling securities,
and the availability of securities or of purchasers or sellers of securities;
furnishing analyses and reports concerning issues, industries, securities,
economic factors and trends, portfolio strategy and the performance of accounts;
and effecting securities transactions and performing functions incidental
thereto, such as clearance and settlement.
 
                                       23
<PAGE>   73
 
Although commissions paid on every transaction will, in the judgment of the
Adviser or the Sub-Adviser, be reasonable in relation to the value of the
brokerage services provided, commissions exceeding those which another broker
might charge may be paid to broker-dealers who were selected to execute
transactions on behalf of a Fund and the Adviser's or the Sub-Adviser's other
clients in part for providing advice as to the availability of securities or of
purchasers or sellers of securities and services in effecting securities
transactions and performing functions incidental thereto, such as clearance and
settlement.
 
   
Broker-dealers may be willing to furnish statistical, research and other factual
information or services ("Research") to the Adviser or the Sub-Adviser for no
consideration other than brokerage or underwriting commissions. Securities may
be bought or sold from time to time through such broker-dealers, on behalf of a
Fund. The Trustees (together with the Trustees of the other MFS Funds) have
directed the Adviser to allocate a total of $39,100 of commission business from
the MFS Funds to the Pershing Division of Donaldson Lufkin & Jenrette as
consideration for the annual renewal of certain publications provided by Lipper
Analytical Securities Corporation (which provides information useful to the
Trustees in reviewing the relationship between a Fund and the Adviser and the
Sub-Adviser).
    
 
The Adviser's and the Sub-Adviser's investment management personnel attempt to
evaluate the quality of Research provided by brokers. The Adviser or the
Sub-Adviser sometimes uses evaluations resulting from this effort as a
consideration in the selection of brokers to execute portfolio transactions.
 
The management fee of the Adviser or the Sub-Adviser will not be reduced as a
consequence of the Adviser's receipt of brokerage and research service. To the
extent a Fund's portfolio transactions are used to obtain brokerage and research
services, the brokerage commissions paid by the Fund will exceed those that
might otherwise be paid for such portfolio transactions, or for such portfolio
transactions and research, by an amount which cannot be presently determined.
Such services would be useful and of value to the Adviser or the Sub-Adviser in
serving both a Fund and other clients and, conversely, such services obtained by
the placement of brokerage business of other clients would be useful to the
Adviser or the Sub-Adviser in carrying out its obligations to the Fund. While
such services are not expected to reduce the expenses of the Adviser or the Sub-
Adviser, the Adviser or the Sub-Adviser would, through use of the services,
avoid the additional expenses which would be incurred if it should attempt to
develop comparable information through its own staff.
 
   
In certain instances there may be securities which are suitable for a Fund's
portfolio as well as for that of one or more of the other clients of the
Adviser, any subsidiary of the Adviser or the Sub-Adviser. Investment decisions
for a Fund and for such other clients are made with a view to achieving their
respective investment objectives. It may develop that a particular security is
bought or sold for only one client even though it might be held by, or bought or
sold for, other clients. Likewise, a particular security may be bought for one
or more clients when one or more other clients are selling that same security.
Some simultaneous transactions are inevitable when several clients receive
investment advice from the same investment adviser, particularly when the same
security is suitable for the investment objectives of more than one client. When
two or more clients are simultaneously engaged in the purchase or sale of the
same security, the securities are allocated among clients in a manner believed
by the Adviser to be equitable to each. It is recognized that in some cases this
system could have a detrimental effect on the price or volume of the security as
far as a Fund is concerned. In other cases, however, a Fund believes that its
ability to participate in volume transactions will produce better executions for
the Fund.
 
For the fiscal year ended May 31, 1997, the International Growth Fund paid
brokerage commissions of $325,190 on total transactions of $117,499,906. For the
fiscal year ended May 31, 1997, the International Growth and Income Fund paid
brokerage commissions of $32,101 on total transactions of $14,083,274. For the
fiscal year ended May 31, 1997, the Emerging Markets Equity Fund paid brokerage
commissions of $303,239 on total transactions of $63,317,556.
 
During the fiscal year ended May 31, 1997, the International Growth Fund
acquired and owned securities issued by Deutsche Bank and General Electric
Capital Corp., broker-dealers of this Fund, in the amount of $618,562 and
$204,968, respectively as of May 31, 1997. During the fiscal year ended May 31,
1997, the International Growth and Income Fund acquired and owned securities
issued by Deutsche Bank, a broker-dealer of this Fund, in the amounts of
$223,771 as of May 31, 1997. During the fiscal year ended May 31, 1997, the
Emerging Markets Equity Fund, acquired and owned securities issued by ING Baring
and General Electric Capital Corp., broker-dealers of this Fund, in the amount
of $1,030,047 and $1,059,835, respectively as of May 31, 1997.
    
 
5. SHAREHOLDER SERVICES
 
INVESTMENT AND WITHDRAWAL PROGRAMS -- Each Fund makes available the following
programs designed to enable shareholders to add to their investment or withdraw
from it with a minimum of paper work. These are described below and, in certain
cases, in the Prospectus. The programs involve no extra charge to shareholders
(other than a sales charge in the case of certain Class A share purchases) and
may be changed or discontinued at any time by a shareholder or a Fund.
 
LETTER OF INTENT -- If a shareholder (other than a group purchaser described
below) anticipates purchasing $100,000 or more of Class A shares of a Fund alone
or in combination with all classes of shares of other MFS Funds or MFS Fixed
Fund (a bank collective investment fund) within a 13-month period (or
 
                                       24
<PAGE>   74
 
36-month period, in the case of purchases of $1 million or more), the
shareholder may obtain Class A shares of the Fund at the same reduced sales
charge as though the total quantity were invested in one lump sum by completing
the Letter of Intent section of the Account Application or filing a separate
Letter of Intent application (available from the Shareholder Servicing Agent)
within 90 days of the commencement of purchases. Subject to acceptance by MFD
and the conditions mentioned below, each purchase will be made at a public
offering price applicable to a single transaction of the dollar amount specified
in the Letter of Intent application. The shareholder or his dealer must inform
MFD that the Letter of Intent is in effect each time shares are purchased. The
shareholder makes no commitment to purchase additional shares, but if his
purchases within 13 months (or 36 months in the case of purchases of $1 million
or more) plus the value of shares credited toward completion of the Letter of
Intent do not total the sum specified, he will pay the increased amount of the
sales charge as described below. Instructions for issuance of shares in the name
of a person other than the person signing the Letter of Intent application must
be accompanied by a written statement from the dealer stating that the shares
were paid for by the person signing such Letter. Neither income dividends nor
capital gain distributions taken in additional shares will apply toward the
completion of the Letter of Intent. Dividends and distributions of other MFS
Funds automatically reinvested in shares of a Fund pursuant to the Distribution
Investment Program will also not apply toward completion of the Letter of
Intent.
 
Out of the shareholder's initial purchase (or subsequent purchases if
necessary), 5% of the dollar amount specified in the Letter of Intent
application shall be held in escrow by the Shareholder Servicing Agent in the
form of shares registered in the shareholder's name. All income dividends and
capital gain distributions on escrowed shares will be paid to the shareholder or
to his order. When the minimum investment so specified is completed (either
prior to or by the end of the 13-month period or 36-month period, as
applicable), the shareholder will be notified and the escrowed shares will be
released.
 
If the intended investment is not completed, the Shareholder Servicing Agent
will redeem an appropriate number of the escrowed shares in order to realize
such difference. Shares remaining after any such redemption will be released by
the Shareholder Servicing Agent. By completing and signing the Account
Application or separate Letter of Intent application, the shareholder
irrevocably appoints the Shareholder Servicing Agent his attorney to surrender
for redemption any or all escrowed shares with full power of substitution in the
premises.
 
   
RIGHT OF ACCUMULATION -- A shareholder qualifies for cumulative quantity
discounts on the purchase of Class A shares when his new investment, together
with the current offering price value of all holdings of all Class A, B and C
shares of that shareholder in the MFS Funds or MFS Fixed Fund (a bank collective
investment fund) reaches a discount level. See "Purchases" in the Prospectus for
the sales charges on quantity discounts. For example, if a shareholder owns
shares with a current offering price value of $75,000 and purchases an
additional $25,000 of Class A shares of a Fund, the sales charge for the $25,000
purchase would be at the rate of 4% (the rate applicable to single transactions
of $100,000). A shareholder must provide the Shareholder Servicing Agent (or his
investment dealer must provide MFD) with information to verify that the quantity
sales charge discount is applicable at the time the investment is made.
 
SUBSEQUENT INVESTMENT BY TELEPHONE -- Each shareholder may purchase additional
shares of any MFS Fund by telephoning the Shareholder Servicing Agent toll-free
at (800) 225-2606. The minimum purchase amount is $50 and the maximum purchase
amount is $100,000. Shareholders wishing to avail themselves of this telephone
purchase privilege must so elect on their Account Application and designate
thereon a bank and account number from which purchases will be made. If a
telephone purchase request is received by the Shareholder Servicing Agent on any
business day prior to the close of regular trading on the Exchange (generally,
4:00 p.m., Eastern time), the purchase will occur at the closing net asset value
of the shares purchased on that day. The Shareholder Servicing Agent may be
liable for any losses resulting from unauthorized telephone transactions if it
does not follow reasonable procedures designed to verify the identity of the
caller. The Shareholder Servicing Agent will request personal or other
information from the caller, and will normally also record calls. Shareholders
should verify the accuracy of confirmation statements immediately after their
receipt.
    
 
DISTRIBUTION INVESTMENT PROGRAM -- Distributions of dividends and capital gains
made by a Fund with respect to a particular class of shares may be automatically
invested in shares of the same class of one of the other MFS Funds, if shares of
the fund are available for sale. Such investments will be subject to additional
purchase minimums. Distributions will be invested at net asset value (exclusive
of any sales charge) and will not be subject to any CDSC. Distributions will be
invested at the close of business on the payable date for the distribution. A
shareholder considering the Distribution Investment Program should obtain and
read the prospectus of the other fund and consider the differences in objectives
and policies before making any investment.
 
SYSTEMATIC WITHDRAWAL PLAN: A shareholder may direct the Shareholder Servicing
Agent to send him (or anyone he designates) regular periodic payments based upon
the value of his account. Each payment under a Systematic Withdrawal Plan
("SWP") must be at least $100, except certain limited circumstances. The
aggregate withdrawals of Class B and Class C shares in any year pursuant to a
SWP generally are limited to 10% of the value of the account at the time of
 
                                       25
<PAGE>   75
 
establishment of the SWP. SWP payments are drawn from the proceeds of share
redemptions (which would be a return of principal and, if reflecting a gain,
would be taxable). Redemptions of Class B and Class C shares will be made in the
following order: (i) any "Reinvested Shares"; (ii) to the extent necessary, any
"Free Amount"; and (iii) to the extent necessary, the "Direct Purchase" subject
to the lowest CDSC (as such terms are defined under "Information Concerning
Shares of the Funds -- Contingent Deferred Sales Charge" in the Prospectus). The
CDSC will be waived in the case of redemptions of Class B and Class C shares
pursuant to a SWP, but will not be waived in the case of SWP redemptions of
Class A shares which are subject to a CDSC. To the extent that redemptions for
such periodic withdrawals exceed dividend income reinvested in the account, such
redemptions will reduce and may eventually exhaust the number of shares in the
shareholder's account. All dividend and capital gain distributions for an
account with a SWP will be received in full and fractional shares of a Fund at
the net asset value in effect at the close of business on the record date for
such distributions. To initiate this service, shares generally having an
aggregate value of at least $5,000 either must be held on deposit by, or
certificates for such shares must be deposited with, the Shareholder Servicing
Agent. With respect to Class A shares, maintaining a withdrawal plan
concurrently with an investment program would be disadvantageous because of the
sales charges included in share purchases and the imposition of a CDSC on
certain redemptions. The shareholder may deposit into the account additional
shares of a Fund, change the payee or change the dollar amount of each payment.
The Shareholder Servicing Agent may charge the account for services rendered and
expenses incurred beyond those normally assumed by a Fund with respect to the
liquidation of shares. No charge is currently assessed against the account, but
one could be instituted by the Shareholder Servicing Agent on 60 days' notice in
writing to the shareholder in the event that a Fund ceases to assume the cost of
these services. Each Fund may terminate any SWP for an account if the value of
the account falls below $5,000 as a result of share redemptions (other than as a
result of a SWP) or an exchange of shares of the Fund for shares of another MFS
Fund. Any SWP may be terminated at any time by either the shareholder or the
Fund.
 
INVEST BY MAIL: Additional investments of $50 or more may be made at any time by
mailing a check payable to a Fund directly to the Shareholder Servicing Agent.
The shareholder's account number and the name of his investment dealer must be
included with each investment.
 
GROUP PURCHASES: A bona fide group and all its members may be treated as a
single purchaser and, under the Right of Accumulation (but not the Letter of
Intent) obtain quantity sales charge discounts on the purchase of Class A shares
if the group (1) gives its endorsement or authorization to the investment
program so it may be used by the investment dealer to facilitate solicitation of
the membership, thus effecting economies of sales effort; (2) has been in
existence for at least six months and has a legitimate purpose other than to
purchase mutual fund shares at a discount; (3) is not a group of individuals
whose sole organizational nexus is as credit cardholders of a company,
policyholders of an insurance company, customers of a bank or broker-dealer,
clients of an investment adviser or other similar groups; and (4) agrees to
provide certification of membership of those members investing money in the MFS
Funds upon the request of MFD.
 
   
AUTOMATIC EXCHANGE PLAN: Shareholders having account balances of at least $5,000
in any MFS Fund may participate in the Automatic Exchange Plan. The Automatic
Exchange Plan provides for automatic exchanges of funds from the shareholder's
account in an MFS Fund for investment in the same class of shares of other MFS
Funds selected by the shareholder if such MFS Fund is available for sale. Under
the Automatic Exchange Plan, transfers of at least $50 each may be made to up to
six different funds effective on the seventh day of each month or of every third
month, depending whether monthly or quarterly exchanges are elected by the
shareholder. If the seventh day of the month is not a business day, the
transaction will be processed on the next business day. Generally, the initial
exchange will occur after receipt and processing by the Shareholder Servicing
Agent of an application in good order. Exchanges will continue to be made from a
shareholder's account in any MFS Fund, as long as the balance of the account is
sufficient to complete the exchanges. Additional payments made to a
shareholder's account will extend the period that exchanges will continue to be
made under the Automatic Exchange Plan. However, if additional payments are
added to an account subject to the Automatic Exchange Plan shortly before an
exchange is scheduled, such funds may not be available for exchanges until the
following month; therefore, care should be used to avoid inadvertently
terminating the Automatic Exchange Plan through exhaustion of the account
balance.
    
 
No transaction fee for exchanges will be charged in connection with the
Automatic Exchange Plan. However, exchanges of shares of MFS Money Market Fund,
MFS Government Money Market Fund and Class A shares of MFS Cash Reserve Fund
will be subject to any applicable sales charge. Changes in amounts to be
exchanged to each fund, the funds to which exchanges are to be made and the
timing of exchanges (monthly or quarterly), or termination of a shareholder's
participation in the Automatic Exchange Plan will be made after instructions in
writing or by telephone (an "Exchange Change Request") are received by the
Shareholder Servicing Agent in proper form (i.e., if in writing -- signed by the
record owner(s) exactly as shares are registered; if by telephone -- proper
account identification is given by the dealer or shareholder of record). Each
Exchange Change Request (other than termination of participation in the program)
must involve at least $50. Generally, if an Exchange Change Request is received
by telephone or in writing before the close of business on the last business
 
                                       26
<PAGE>   76
 
day of a month, the Exchange Change Request will be effective for the following
month's exchange.
 
A shareholder's right to make additional investments in any of the MFS Funds, to
make exchanges of shares from one MFS Fund to another and to withdraw from an
MFS Fund, as well as a shareholder's other rights and privileges are not
affected by a shareholder's participation in the Automatic Exchange Plan.
 
The Automatic Exchange Plan is part of the Exchange Privilege. For additional
information regarding the Automatic Exchange Plan, including the treatment of
any CDSC, see "Exchange Privilege" below.
 
REINSTATEMENT PRIVILEGE: Shareholders of each Fund and shareholders of the other
MFS Funds (except MFS Money Market Fund, MFS Government Money Market Fund and
holders of Class A shares of MFS Cash Reserve Fund in the case where shares of
such funds are acquired through direct purchase or reinvested dividends) who
have redeemed their shares have a one-time right to reinvest the redemption
proceeds in the same class of shares of any of the MFS Funds (if shares of the
fund are available for sale) at net asset value (without a sales charge) and, if
applicable, with credit for any CDSC paid. In the case of proceeds reinvested in
MFS Money Market Fund, MFS Government Money Market Fund and Class A shares of
MFS Cash Reserve Fund, the shareholder has the right to exchange the acquired
shares for shares of another MFS Fund at net asset value pursuant to the
exchange privilege described below. Such a reinvestment must be made within 90
days of the redemption and is limited to the amount of the redemption proceeds.
If the shares credited for any CDSC paid are then redeemed within six years of
the initial purchase in the case of Class B shares or within 12 months of the
initial purchase in the case of Class C shares and certain Class A shares, a
CDSC will be imposed upon redemption. Although redemptions and repurchases of
shares are taxable events, a reinvestment within a certain period of time in the
same fund may be considered a "wash sale" and may result in the inability to
recognize currently all or a portion of a loss realized on the original
redemption for federal income tax purposes. Please see your tax adviser for
further information.
 
   
EXCHANGE PRIVILEGE -- Subject to the requirements set forth below, some or all
of the shares of the same class in an account with a Fund for which payment has
been received by the Fund (i.e. an established account) may be exchanged for
shares of the same class of any of the other MFS Funds (if available for sale
and if the purchaser is eligible to purchase the class of shares) at net asset
value. Exchanges will be made only after instructions in writing or by telephone
(an "Exchange Request") are received for an established account by the
Shareholder Servicing Agent.
    
 
Each Exchange Request must be in proper form (i.e., if in writing -- signed by
the record owner(s) exactly as the shares are registered; if by
telephone -- proper account identification is given by the dealer or shareholder
of record), and each exchange must involve either shares having an aggregate
value of at least $1,000 ($50 in the case of retirement plan participants whose
sponsoring organizations subscribe to MFS Fundamental 401(k) Plan or another
similar 401(k) recordkeeping system made available by the Shareholder Servicing
Agent) or all the shares in the account. Each exchange involves the redemption
of the shares of the Fund to be exchanged and the purchase at net asset value
(i.e., without a sales charge) of shares of the same class of the other MFS
Fund. Any gain or loss on the redemption of the shares exchanged is reportable
on the shareholder's federal income tax return, unless both the shares received
and the shares surrendered in the exchange are held in a tax-deferred retirement
plan or other tax-exempt account. No more than five exchanges may be made in any
one Exchange Request by telephone. If the Exchange Request is received by the
Shareholder Servicing Agent prior to the close of regular trading on the
Exchange, the exchange usually will occur on that day if all the requirements
set forth above have been complied with at that time. However, payment of the
redemption proceeds by a Fund, and thus the purchase of shares of the other MFS
Fund, may be delayed for up to seven days if the Fund determines that such a
delay would be in the best interest of all its shareholders. Investment dealers
which have satisfied criteria established by MFD may also communicate a
shareholder's Exchange Request to MFD by facsimile subject to the requirements
set forth above.
 
No CDSC is imposed on exchanges among the MFS Funds, although liability for the
CDSC is carried forward to the exchanged shares. For purposes of calculating the
CDSC upon redemption of shares acquired in an exchange, the purchase of shares
acquired in one or more exchanges is deemed to have occurred at the time of the
original purchase of the exchanged shares.
 
Additional information with respect to any of the MFS Funds, including a copy of
its current prospectus, may be obtained from investment dealers or the
Shareholder Servicing Agent. A shareholder considering an exchange should obtain
and read the prospectus of the other fund and consider the differences in
objectives and policies before making any exchange. Shareholders of the other
MFS Funds (except MFS Money Market Fund, MFS Government Money Market Fund and
Class A Shares of MFS Cash Reserve Fund for shares acquired through direct
purchase and dividends reinvested prior to June 1, 1992) have the right to
exchange their shares for shares of each Fund, subject to the conditions, if
any, set forth in their respective prospectuses. In addition, unitholders of the
MFS Fixed Fund (a bank collective investment fund) have the right to exchange
their units (except units acquired through direct purchases) for shares of a
Fund, subject to the conditions, if any, imposed upon such unitholders by the
MFS Fixed Fund.
 
Any state income tax advantages for investment in shares of each state-specific
series of MFS Municipal Series Trust may only benefit residents of such states.
Investors should consult with their own tax advisers to be sure this is an
 
                                       27
<PAGE>   77
 
appropriate investment, based on their residency and each state's income tax
laws.
 
The exchange privilege (or any aspect of it) may be changed or discontinued and
is subject to certain limitations (see "Purchases" in the Prospectus).
 
TAX-DEFERRED RETIREMENT PLANS -- Shares of each Fund may be purchased by all
types of tax-deferred retirement plans. MFD makes available through investment
dealers plans and/or custody agreements for the following:
 
     Individual Retirement Accounts (IRAs) (for individuals and their
     non-employed spouses who desire to make limited contributions to a
     tax-deferred retirement program and, if eligible, to receive a federal
     income tax deduction for amounts contributed);
 
     Simplified Employee Pension (SEP-IRA) Plans;
 
     Retirement Plans Qualified under Section 401(k) of the Internal Revenue
     Code of 1986, as amended;
 
     403(b) Plans (deferred compensation arrangements for employees of public
     school systems and certain non-profit organizations); and
 
     Certain other qualified pension and profit-sharing plans.
 
The plan documents provided by MFD designate a trustee or custodian (unless
another trustee or custodian is designated by the individual or group
establishing the plan) and contain specific information about the plans. Each
plan provides that dividends and distributions will be reinvested automatically.
For further details with respect to any plan, including fees charged by the
trustee, custodian or MFD, tax consequences and redemption information, see the
specific documents for that plan. Plan documents other than those provided by
MFD may be used to establish any of the plans described above. Third party
administrative services, available for some corporate plans, may limit or delay
the processing of transactions.
 
An investor should consult with his tax adviser before establishing any of the
tax-deferred retirement plans described above.
 
6. TAX STATUS
 
Each Fund has elected to be treated and intends to qualify each year as a
"regulated investment company" under Subchapter M of the Internal Revenue Code
of 1986, as amended (the "Code"), by meeting all applicable requirements of
Subchapter M, including requirements as to the nature of the Fund's gross
income, the amount of Fund distributions, and the composition and holding period
of the Fund's portfolio assets. Because each Fund intends to distribute all of
its net investment income and net realized capital gains to shareholders in
accordance with the timing requirements imposed by the Code, it is not expected
that any Fund will be required to pay any federal income or excise taxes,
although a Fund's foreign-source income may be subject to foreign withholding
taxes. If a Fund should fail to qualify as a "regulated investment company" in
any year, the Fund would incur a regular corporate federal income tax upon its
taxable income and Fund distributions would generally be taxable as ordinary
dividend income to the shareholders.
 
   
Shareholders of each Fund normally will have to pay federal income taxes, and
any state or local taxes, on the dividends and capital gain distributions they
receive from the Fund. Dividends from ordinary income and any distributions from
net short-term capital gains are taxable to shareholders as ordinary income for
federal income tax purposes whether the distributions are paid in cash or
reinvested in additional shares. Distributions of net capital gains (i.e., the
excess of net long-term capital gains over net short-term capital losses),
whether paid in cash or reinvested in additional shares, are taxable to a Fund's
shareholders as long-term capital gains for federal income tax purposes without
regard to the length of time the shareholders have held their shares. Any Fund
dividend that is declared in October, November or December of any calendar year
that is payable to shareholders of record in such a month, and that is paid the
following January will be treated as if received by shareholders on December 31
of the year in which the dividend is declared. The Fund will notify shareholders
regarding the federal tax status of its distributions after the end of each
calendar year.
 
Any Fund distribution will have the effect of reducing the per share net asset
value of shares in the Fund by the amount of the distribution. Shareholders
purchasing shares shortly before the record date of any distribution may thus
pay the full price for the shares and then effectively receive a portion of the
purchase price back as a taxable distribution.
 
In general, any gain or loss realized upon a taxable disposition of shares of a
Fund by a shareholder that holds such shares as a capital asset will be treated
as a long-term capital gain or loss if the shares have been held for more than
twelve months and otherwise as a short-term capital gain or loss. However, any
loss realized upon a disposition of shares in a Fund held for six months or less
will be treated as a long-term capital loss to the extent of any distributions
of net capital gain made with respect to those shares. Any loss realized upon a
redemption of shares may also be disallowed under rules relating to wash sales.
Gain may be increased (or loss reduced) upon a redemption of Class A shares of a
Fund within ninety days after their purchase followed by any purchase (including
purchases by exchange or by reinvestment) without payment of an additional sales
charge of Class A shares of that Fund or of another MFS Fund (or any other
shares of an MFS Fund generally sold subject to a sales charge).
 
Each Fund's current dividend and accounting policies will affect the amount,
timing and character of distributions to shareholders, and may, under certain
circumstances, make an economic return of capital taxable to shareholders. A

Fund's investments in zero coupon bonds, deferred interest bonds, payment in
kind bonds, and certain securities purchased at a market discount will cause the
Fund to recognize income prior to the receipt of cash payments with respect to
those securities. In order to distribute this income and avoid a tax on the
Fund, the Fund may be required to liquidate portfolio securities that it might
otherwise have continued to hold, potentially resulting in additional taxable
gain or loss to the Fund.
 
Each Fund's transactions in options, Futures Contracts and Forward Contracts
will be subject to special tax rules that may affect the amount, timing and
character of Fund income and distributions to shareholders. For example, certain
positions held by a Fund on the last business day of each taxable year will be
marked to market (i.e., treated as if closed out) on that day, and any gain or
loss associated with the positions will be treated as 60% long-term and 40%
short term capital gain or loss. Certain positions held by a Fund that
substantially diminish its risk of loss with respect to other positions in its
portfolio may constitute "straddles," and may be subject to special tax rules
that would cause deferral of Fund losses, adjustments in the holding periods of
Fund securities, and conversion of short-term into long-term capital losses.
Certain tax elections exist for straddles that may alter the effects of these
rules. Each Fund will limit its activities in options, Futures Contracts,
Forward Contracts and swaps and related transactions to the extent necessary to
meet the requirements of Subchapter M of the Code.
 
Special tax considerations apply with respect to foreign investments of a Fund.
Foreign exchange gains and losses realized by a Fund will generally be treated
as ordinary income and losses. The holding of foreign currencies for non-hedging
purposes and investment by a Fund in certain "passive foreign investment
companies" may be limited in order to avoid a tax on the Fund.
 
Investment income received by a Fund from foreign securities may be subject to
foreign income taxes withheld at the source. The United States has entered into
tax treaties with many foreign countries that may entitle a Fund to a reduced
rate of tax or an exemption from tax on such income; each Fund intends to
qualify for treaty reduced rates where available. It is not possible, however,
to determine a Fund's effective rate of foreign tax in advance since the amount
of the Fund's assets to be invested within various countries is not known. If a
Fund holds more than 50% of its assets in foreign stock and securities at the
close of its taxable year, the Fund may elect to "pass through" to the Fund's
shareholders foreign income taxes paid. If the Fund so elects, shareholders will
be required to treat their pro-rata portion of the foreign income taxes paid by
the Fund as part of the amounts distributed to them by the Fund and thus
includable in their gross income for federal income tax purposes. Shareholders
who itemize deductions would then be allowed to claim a deduction or credit (but
not both) on their federal income tax returns for such amounts, subject to
certain limitations. Shareholders who do not itemize deductions would be able
(subject to such limitations) to claim a credit but not a deduction. No
deductions for such amounts will be permitted to individuals in computing their
alternative minimum tax liability. If a Fund does not qualify or elect to "pass
through" to its shareholders foreign income taxes paid by it, shareholders will
not be able to claim any deduction or credit for any part of the foreign taxes
paid by the Fund.
 
Dividends and certain other payments to persons who are not citizens or
residents of the United States or U.S. entities ("Non-U.S. Persons") are
generally subject to U.S. tax withholding at a rate of 30%. Each Fund intends to
withhold U.S. federal income tax at the rate of 30% on taxable dividends and
other payments to Non-U.S. Persons that are subject to such withholding,
regardless of whether a lower rate may be permitted under an applicable treaty.
Any amounts overwithheld may be recovered by such persons by filing a claim for
refund with the U.S. Internal Revenue Service within the time period appropriate
to such claims. Distributions received from a Fund by Non-U.S. Persons also may
be subject to tax under the laws of their own jurisdictions. Each Fund is also
required in certain circumstances to apply backup withholding at a rate of 31%
on taxable dividends and redemption proceeds paid to any shareholder (including
a Non-U.S. Person) who does not furnish to the Fund certain information and
certifications or who is otherwise subject to backup withholding. Backup
withholding will not, however, be applied to payments that have been subject to
30% withholding.
    
 
No Fund will be required to pay Massachusetts income or excise taxes as long as
it qualifies as a regulated investment company under the Code.
 
   
7. DISTRIBUTION PLAN
 
The Trustees have adopted a Distribution Plan for each of the Class A, Class B
and Class C shares of each Fund (the "Distribution Plan") pursuant to Section
12(b) of the 1940 Act and Rule 12b-1 thereunder (the "Rule") after having
concluded that there is a reasonable likelihood that the Distribution Plan would
benefit the applicable Fund and each respective class of shareholders. The
provisions of the Distribution Plan are severable with respect to each Fund and
each class of shares offered by each Fund. The Distribution Plan is designed to
promote sales, thereby increasing the net assets of each Fund. Such an increase
may reduce the expense ratio to the extent a Fund's fixed costs are spread over
a larger net asset base. Also, an increase in net assets may lessen the adverse
effects that could result were a Fund required to liquidate portfolio securities
to meet redemptions. There is, however, no assurance that the net assets of a
Fund will increase or that the other benefits referred to above will be
realized.
 
The Distribution Plan is described in the Prospectus under the caption
"Distribution Plan," which is incorporated herein by reference. The following
information supplements this Prospectus discussion.
    
 
                                       29
<PAGE>   79
 
   
SERVICE FEES: With respect to Class A shares, no service fees will be paid to
any insurance company which has entered into an agreement with the applicable
Fund and MFD that permits such insurance company to purchase Class A shares from
the Fund at their net asset value in connection with annuity agreements issued
in connection with the insurance company's separate accounts. Dealers may from
time to time be required to meet certain other criteria in order to receive
service fees.
 
MFD or its affiliates shall be entitled to receive any service fee payable under
the Distribution Plan for which there is no dealer of record or for which
qualification standards have not been met as partial consideration for personal
services and/or account maintenance services performed by MFD or its affiliates
for shareholder accounts.
 
DISTRIBUTION FEES: The purpose of distribution payments to MFD under the
Distribution Plan is to compensate MFD for its distribution services to the
Funds. MFD pays commissions to dealers as well as expenses of printing
prospectuses and reports used for sales purposes, expenses with respect to the
preparation and printing of sales literature and other distribution related
expenses, including, without limitation, the cost necessary to provide
distribution-related services, or personnel, travel, office expenses and
equipment.
 
DISTRIBUTION AND SERVICE FEES PAID DURING THE FUNDS' LAST FISCAL PERIOD: During
the fiscal year ended May 31, 1997, the Funds paid the following Distribution
Plan expenses:

GENERAL: The Distribution Plan will remain in effect until August 1, 1998, and
will continue in effect thereafter only if such continuance is specifically
approved at least annually by vote of both the Trustees and a majority of the
Trustees who are not "interested persons" or financially interested parties to
such Plan ("Distribution Plan Qualified Trustees"). The Distribution Plan also
requires that the applicable Fund and MFD each shall provide to the Trustees,
and the Trustees shall review, at least quarterly, a written report of the
amounts expended (and purposes therefor) under such Plan. The Distribution Plan
may be terminated at any time by a vote of a majority of the Distribution Plan
Qualified Trustees or by vote of the holders of a majority of the respective
class of the applicable Fund's shares (as defined in "Investment Restrictions").
All agreements relating to the Distribution Plan entered into between a Fund or
MFD and other organizations must be approved by the Board of Trustees, including
a majority of the Distribution Plan Qualified Trustees. Agreements under the
Distribution Plan must be in writing, will be terminated automatically if
assigned, and may be terminated at any time without payment or any penalty, by
vote of a majority of the Distribution Plan Qualified Trustees or by vote of the
holders of a majority of the respective class of the applicable Fund's shares.
The Distribution Plan may not be amended to increase materially the amount of
permitted distribution expenses without the approval of a majority of the
respective class of the applicable Fund's shares (as defined in "Investment
Restrictions") or may not be materially amended in any case without a vote of
the Trustees and a majority of the Distribution Plan Qualified Trustees. The
selection and nomination of Distribution Plan Qualified Trustees shall be
committed to the discretion of the non-interested Trustees then in office. No
Trustee who is not an "interested person" has any financial interest in the
Distribution Plan or in any related agreement.
    
 
8. DETERMINATION OF NET ASSET VALUE AND PERFORMANCE
 
   
NET ASSET VALUE: The net asset value per share of each class of each Fund is
determined each day during which the Exchange is open for trading. (As of the
date of this SAI, the Exchange is open for trading every weekday except for the
following holidays (or the days on which they are observed): New Year's Day,
Martin Luther King Day, Presidents' Day, Good Friday, Memorial Day, Independence
Day, Labor Day, Thanksgiving Day and Christmas Day.)
    
 
This determination is made once each day as of the close of regular trading on
the Exchange by deducting the amount of the liabilities attributable to the
class from the value of the assets attributable to the class and dividing the
difference by the number of shares of the class outstanding. Equity securities
in a Fund's portfolio are valued at the last sale price on the exchange on which
they are primarily traded or on the NASDAQ system for unlisted national market
issues, or at the last quoted bid price for listed securities in which there
were no sales during the day or for unlisted securities not reported on the
NASDAQ system. Bonds and other fixed income securities (other than short-term
obligations) of U.S. issuers in a Fund's portfolio are valued on the basis of
valuations furnished by a pricing service which utilizes both dealer-supplied
valuations and electronic data processing techniques which take into account
appropriate factors such as institu-
 
                                       30
<PAGE>   80
 
tional-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, futures contracts and options in a Fund's portfolio (other than
short-term obligations) 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, unless such securities are reported on the NASDAQ system, in
which case they are valued at the last sale price or, if no sales occurred
during the day, at the last quoted bid price. Short-term obligations in a Fund'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 there are no such quotations or valuations are
valued at fair value as determined in good faith by or at the direction of the
Board of Trustees.
 
Generally, trading in foreign securities is substantially completed each day at
various times prior to the close of regular trading on the Exchange.
Occasionally, events affecting the values of such securities may occur between
the times at which they are determined and the close of regular trading on the
Exchange which will not be reflected in the computation of a Fund's net asset
value unless the Trustees deem that such event would materially affect the net
asset value in which case an adjustment would be made.
 
All investments and assets are expressed in U.S. dollars based upon current
currency exchange rates. A share's net asset value is effective for orders
received by the dealer prior to its calculation and received by MFD or its
agent, the Shareholder Servicing Agent, prior to the close of that business day.
 
PERFORMANCE INFORMATION
 
   
TOTAL RATE OF RETURN: Each Fund will calculate its total rate of return for each
class of shares for certain periods by determining the average annual compounded
rates of return over those periods that would cause an investment of $1,000
(made with all distributions reinvested and reflecting the CDSC or the maximum
public offering price) to reach the value of that investment at the end of the
periods. Each Fund may also calculate (i) a total rate of return, which is not
reduced by the CDSC (4% maximum for Class B shares and 1% maximum for Class C
shares) and therefore may result in a higher rate of return, (ii) a total rate
of return assuming an initial account value of $1,000, which will result in a
higher rate of return since the value of the initial account will not be reduced
by the sales charge applicable to Class A shares (4.75% maximum) and/or (iii)
total rates of return which represent aggregate performance over a period or
year-by-year performance, and which may or may not reflect the effect of the
maximum or other sales charge or CDSC. Each Fund offers multiple classes of
shares which were initially offered for sale to the public on different dates.
The calculation of total rate of return for a class of shares which initially
was offered for sale to the public subsequent to another class of shares of each
Fund is based both on (i) the Performance of the Fund's newer class from the
date it initially was offered for sale to the public and (ii) the performance of
each Fund's oldest class from the date it initially was offered for sale to the
public up to the date that the newer class initially was offered for sale to the
public.
 
As discussed in the Prospectus, the sales charges, expenses and expense ratios,
and therefore the performance, of each Fund's classes of shares differ. In
calculating total rate of return for a newer class of shares in accordance with
certain formulas required by the SEC, the performance will be adjusted to take
into account the fact that the newer class is subject to a different sales
charge than the oldest class (e.g., if the newer class is Class A shares, the
total rate of return quoted will reflect the deduction of the initial sales
charge applicable to Class A shares; if the newer class is Class B shares, the
total rate of return quoted will reflect the deduction of the CDSC applicable to
Class B share). However, the performance will not be adjusted to take into
account the fact that the newer class of shares bears different class specific
expenses than the oldest class of shares (e.g., Rule 12b-1 fees). Therefore, the
total rate of return quoted for a newer class of shares will differ from the
return that would be quoted had the newer class of shares been outstanding for
the entire period over which the calculation is based (i.e., the total rate of
return quoted for the newer class will be higher than the return that would have
been quoted had the newer class of shares been outstanding for the entire period
over which the calculation is based if the class specific expenses for the newer
class are higher than the class specific expenses of the oldest class, and the
total rate of return quoted for the newer class will be lower than the return
that would be quoted had the newer class of shares been outstanding for this
entire period if the class specific expenses for the newer class are lower than
the class specific expenses of the oldest class).
 
Total rate of return quotations for each class are presented in Appendix A
attached hereto under the heading "Performance Quotations."
 
PERFORMANCE RESULTS: The performance results for Class A shares presented in
Appendix A hereto under the heading "Performance Results" assume an initial
investment of
    
 
                                       31
<PAGE>   81
 
   
$10,000 in Class A shares of each fund and cover the period from October 24,
1995 to December 31, 1996. It has been assumed that dividend and capital gain
distributions were reinvested in additional shares. These performance results,
as well as any yield or total rate of return quotation provided by the Funds,
should not be considered as representative of the performance of the Funds in
the future since the net asset value and public offering price of shares of the
Funds will vary based not only on the type, quality and maturities of the
securities held in each of the Fund's portfolio, but also on changes in the
current value of such securities and on changes in the expenses of the Funds.
These factors and possible differences in the methods used to calculate yields
and total rates of return should be considered when comparing the yield and
total rate of return of the Funds to yields and total rates of return published
for other investment companies or other investment vehicles. Total rate of
return reflects the performance of both principal and income. The current net
asset value of shares and account balance information may be obtained by calling
1-800-MFS-TALK (637-8355).
 
YIELD: Any yield quotation for a class of shares of the International Growth and
Income Fund is based on the annualized net investment income per share of that
class over a 30-day period. The yield is calculated by dividing the net
investment income per share allocated to a particular class of the Fund earned
during the period by the maximum offering price per share of such class on the
last day of that period. The resulting figure is then annualized. Net investment
income per share of a class is determined by dividing (i) the dividends and
interest earned by the Fund allocated to the class during the period, minus
accrued expenses of such class for the period, by (ii) the average number of
shares of such class entitled to receive dividends during the period multiplied
by the maximum offering price per share of such class on the last day of the
period. The Fund's yield calculations assume a maximum sales charge of 4.75% in
the case of Class A shares and no payment of any CDSC in the case of Class B and
Class C shares.
 
The yield quotations for the International Growth and Income Fund for each class
are presented in Appendix A attached hereto under the heading "Performance
Quotations".
    
 
CURRENT DISTRIBUTION RATE: Yield, which is calculated according to a formula
prescribed by the SEC, is not indicative of the amounts which were or will be
paid to the International Growth and Income Fund shareholders. Amounts paid to
shareholders of each class are reflected in the quoted "current distribution
rate" for that class. The current distribution rate for a class is computed by
dividing the total amount of dividends per share paid by the Fund to
shareholders of that class during the past twelve months by the maximum public
offering price of that class at the end of such period. Under certain
circumstances, such as when there has been a change in the amount of dividend
payout, or a fundamental change in investment policies, it might be appropriate
to annualize the dividends paid over the period such policies were in effect,
rather than using the dividends during the past twelve months. The current
distribution rate differs from the yield computation because it may include
distributions to shareholders from sources other than dividends and interest,
such as premium income for option writing, short-term capital gains and return
of invested capital, and is calculated over a different period of time. The
Fund's current distribution rate calculation for Class A shares assumes a
maximum sales charge of 4.75%. The Fund's current distribution rate calculation
for Class B and Class C shares assumes no CDSC is paid.
 
   
The current distribution rate calculation for each Class of shares of the
International Growth and Income Fund are presented in Appendix A attached hereto
under the heading "Performance Quotations".
 
GENERAL: From time to time each Fund may, as appropriate, quote Fund rankings or
reprint all or a portion of evaluations of fund performance and operations
appearing in various independent publications, including but not limited to the
following: Money, Fortune, U.S. News and World Report, Kiplinger's Personal
Finance, The Wall Street Journal, Barron's, Investors Business Daily, Newsweek,
Financial World, Financial Planning, Investment Advisor, USA Today, Pensions and
Investments, SmartMoney, Forbes, Global Finance, Registered Representative,
Institutional Investor, the Investment Company Institute, Johnson's Charts,

Money, Strangers Investment Advisor, Financial Planning on Wall Street, Standard
and Poor's, Individual Investor, The 100 Best Mutual Funds You Can Buy, by
Gordon K. Williamson, Consumer Price Index, and Sanford C. Bernstein & Co. Fund
performance may also be compared to the performance of other mutual funds
tracked by financial or business publications or periodicals. Each Fund may also
quote evaluations mentioned in independent radio or television broadcasts and
use charts and graphs to illustrate the past performance of various indices such
as those mentioned above and illustrations using hypothetical rates of return to
illustrate the effects of compounding and tax-deferral. Each Fund may advertise
examples of the effects of periodic investment plans, including the principle of
dollar cost averaging. In such a program, an investor invests a fixed dollar
amount in a fund at periodic intervals, thereby purchasing fewer shares when
prices are high and more shares when prices are low. While such a strategy does
not assure a profit or guard against a loss in a declining market, the
investor's average cost per share can be lower than if fixed numbers of shares
are purchased at the same intervals.
    
 
From time to time, each Fund and MFD may discuss or quote a Fund's current
portfolio manager(s) as well as other investment personnel, including such
persons' views on: various foreign and emerging market economies; securities
 
                                       32

markets; portfolio securities and their issuers; investment philosophies,
strategies, techniques and criteria used in the selection of securities to be
purchased or sold for the Fund; the Fund's portfolio holdings; the investment
research and analysis process; the formulation and evaluation of investment
recommendations; the assessment and evaluation of credit, interest rate, market
and economic risks; and similar and related matters. In addition, from time to
time each Fund and MFD may discuss a Fund's current or anticipated allocations
of the Fund's securities by country or region. Any such allocations are subject
to change.
 
From time to time the Fund may also discuss or quote the views of its
distributor, its investment adviser and other financial planning, legal, tax,
accounting, insurance, estate planning and other professionals, or from surveys,
regarding individual and family financial planning. Such views may include
information regarding: retirement planning; tax management strategies; estate
planning; general investment techniques (e.g., asset allocation and disciplined
saving and investing); business succession; ideas and information provided
through the MFS Heritage Planning(sm) program, an intergenerational financial
planning assistance program; issues with respect to insurance (e.g., disability
and life insurance and Medicare supplemental insurance); and issues regarding
financial and health care management for elderly. MFS FIRSTS: MFS has a long
history of innovations.

    RIGHTS AND LIABILITIES
 
The Declaration of Trust permits the Trustees to issue an unlimited number of
full and fractional Shares of Beneficial Interest (without par value) of one or
more separate series and to divide or combine the shares of any series into a
greater or lesser number of shares without thereby changing the proportionate
beneficial interests in that series. The Trustees have currently authorized
shares of each Fund and one other series. The Declaration of Trust further
authorizes the Trustees to classify or reclassify any series of shares into one
or more classes. Pursuant thereto, the Trustees have
 
                                       33
<PAGE>   83
 
   
authorized the issuance of four classes of shares of each series of the Trust
(Class A, Class B, Class C and Class I shares). Each share of a class of a Fund
represents an equal proportionate interest in the assets of the Fund allocable
to that class. Upon liquidation of a Fund, shareholders of each class of the
Fund are entitled to share pro rata in the Fund's net assets allocable to such
class available for distribution to shareholders. The Trust reserves the right
to create and issue a number of series and additional classes of shares, in
which case the shares of each class of a series would participate equally in the
earnings, dividends and assets allocable to that class of the particular series.
    
 
Shareholders are entitled to one vote for each share held and may vote in the
election of Trustees and on other matters submitted to meetings of shareholders.
Although Trustees are not elected annually by the shareholders, the Declaration
of Trust provides that a Trustee may be removed from office at a meeting of
shareholders by a vote of two-thirds of the outstanding shares of the Trust. A
meeting of shareholders will be called upon the request of shareholders of
record holding in the aggregate not less than 10% of the outstanding voting
securities of the Trust. No material amendment may be made to the Declaration of
Trust without the affirmative vote of a majority of the Trust's outstanding
shares (as defined in "Investment Restrictions"). The Trust or any series of the
Trust may be terminated (i) upon the merger or consolidation of the Trust or any
series of the Trust with another organization or upon the sale of all or
substantially all of its assets (or all or substantially all of the assets
belonging to any series of the Trust), if approved by the vote of the holders of
two-thirds of the Trust's or the affected series' outstanding shares voting as a
single class, or of the affected series of the Trust, except that if the
Trustees recommend such merger, consolidation or sale, the approval by vote of
the holders of a majority of the Trust's or the affected series' outstanding
shares will be sufficient, or (ii) upon liquidation and distribution of the
assets of a Fund, if approved by the vote of the holders of two-thirds of its
outstanding shares of the Trust, or (iii) by the Trustees by written notice to
its shareholders. If not so terminated, the Trust will continue indefinitely.
 
The Trust is an entity of the type commonly known as a "Massachusetts business
trust." Under Massachusetts law, shareholders of such a trust may, under certain
circumstances, be held personally liable as partners for its obligations.
However, the Declaration of Trust contains an express disclaimer of shareholder
liability for acts or obligations of the Trust and provides for indemnification
and reimbursement of expenses out of Trust property for any shareholder held
personally liable for the obligations of the Trust. The Declaration of Trust
also provides that the Trust shall maintain appropriate insurance (for example,
fidelity bonding and errors and omissions insurance) for the protection of the
Trust and its shareholders and the Trustees, officers, employees and agents of
the Trust covering possible tort and other liabilities. Thus, the risk of a
shareholder incurring financial loss on account of shareholder liability is
limited to circumstances in which both inadequate insurance existed and the
Trust itself was unable to meet its obligations.
 
The Declaration of Trust further provides that obligations of the Trust are not
binding upon the Trustees individually but only upon the property of the Trust
and that the Trustees will not be liable for any action or failure to act, but
nothing in the Declaration of Trust protects a Trustee against any liability to
which he would otherwise be subject by reason of his willful misfeasance, bad
faith, gross negligence, or reckless disregard of the duties involved in the
conduct of his office.

(1) Class C share performance includes the performance of the Fund's Class B
    shares for periods prior to the commencement of offering of Class C shares
    on June 27, 1996 for FEM and July 1, 1996 for FGF and FGI. Sales charges,
    expenses and expense ratios, and therefore performance, for Class B and
    Class C shares differ. Class C share performance has been adjusted to
    reflect that Class C shares generally are subject to a lower CDSC (unless
    the performance quotation does not give effect to the CDSC) than Class B
    shares. Class C share performance has not, however, been adjusted to reflect
    differences in operating expenses, which generally are not significantly
    different from Class B and Class C shares.
 
(2) Class I share performance includes the performance of the Fund's Class A
    shares for the periods prior to the commencement of offering of Class I
    shares on January 2, 1997. Sales charges, expenses and expense ratios, and
    therefore performance for Class I and A shares differ. Class I share
    performance has been adjusted to reflect that Class I shares are not subject
    to an initial sales charge, whereas Class A shares generally are subject to
    an initial sales charge. Class I share performance has not, however, been
    adjusted to reflect differences in operating expenses (e.g., Rule 12b-1
    fees), which generally are lower for Class I shares. The current
    distribution rate for Class I shares is calculated by annualizing the last
    dividend.

Highlights


[bullet] Several emerging-country equity markets are outperforming the strong
         U.S. stock market, as these countries reap the benefits of both their
         own economic growth and that of developed countries.

[bullet] The renewed strength of the U.S. dollar versus the Japanese yen
         resulted in a strong performance from Japanese blue-chip stocks, many
         of which reached all-time highs.

[bullet] Uncertainty over monetary union continued to be a factor in European
         markets, although some European stocks, such as Volkswagen, performed
         well as they benefited from restructuring.

[bullet] As of May 31, 1997, assets in the three MFS/F&C funds exceeded $241
         million, a 30% increase over the past six months, reflecting a growing
         interest in international investing.

Letter from the Chairman


[photo of A. Keith Brodkin]

Dear Shareholders:

We are pleased to report that, in their second full year of operation, the
MFS/Foreign & Colonial (F&C) International Funds continue to see a steady growth
of assets thanks to investors' renewed interest in international securities
markets, particularly the increasingly vibrant emerging markets.

     In fact, in what may be one of the biggest investment stories of the past
year, some rapidly growing emerging-country equity markets are outperforming the
strong U.S. stock market. Many of these countries are not only reaping the
benefits of their own economic growth, they are also benefiting from demands for
their services and manufactured goods by developed countries. This trend is
reflected in the performance of MFS(R)/Foreign & Colonial Emerging Markets
Equity Fund, whose performance within this category has been quite favorable.

     Assets for the three MFS/F&C funds have reached over $241 million -- a 30%
increase since November 1996. This growing interest in international investing
has come in spite of the continuing strength of the U.S. equity market. We
regard this as a sign of investors' understanding of the need for
diversification across a range of global markets as well as their belief that,
in time, the recent trend of underperformance by international markets will
begin to reverse itself. Before the recent upsurge in U.S. equities, many
overseas markets were outperforming the U.S. market, a situation we expect to
see again, particularly as investors continue to seek the world's highest-growth
areas.

     We are pleased to report that Arnab Kumar Banerji, chief investment officer
of Foreign & Colonial Emerging Markets Ltd. and portfolio manager of MFS/Foreign
& Colonial Emerging Markets Equity Fund, has accepted the additional
responsibility of chief investment officer of Foreign & Colonial Management Ltd.
Dr. Banerji succeeds Tony Thomson, whom we thank for his contribution in helping
launch the MFS/F&C funds.

     Also, we would like to remind investors using annuities for their
long-term, tax-deferred retirement investing that MFS/Foreign & Colonial
Emerging Markets Equity Series, MFS(R)/Foreign & Colonial International Growth
and Income Series, and MFS(R)/Foreign & Colonial International Growth Series are
available as part of the MFS Regatta Gold(R) annuity.

     This annual report to shareholders covers all three MFS/F&C funds. Each of
these funds has varying objectives, which are outlined on page 9 of this report.

     We appreciate your support and welcome any questions or comments you may
have.

MFS/Foreign & Colonial International Funds Overview

Dear Shareholders:

Liquidity continued to underpin international equity markets over the past
year, while disinflationary forces remained in place despite somewhat stronger
world economic growth. International markets experienced increased volatility
following the interest-rate increase by the U.S. Federal Reserve Board in
February, which also caused a setback for the bond markets.

     One of the major events in international markets over this period was the
strength of the U.S. dollar versus the Japanese yen. The yen started the year
at just under 116 to the dollar and fell to a low of 127 on May 2, 1997, a fall
of just under 10%. This weakening resulted in a strong performance from
Japanese blue-chip stocks, many of which reached all-time highs. The story in
the financial services sector was somewhat different. On top of bad-debt
worries, this sector was rocked by the "sokaiya" racketeering scandal at Nomura
Securities.

     In continental Europe, uncertainty over European monetary union (EMU)
remained. Slow growth in Germany raised the prospect that this key EMU member
would have to be creative with its accounting policies in order to meet the
Maastricht criteria, allowing weaker members such as Italy to join at the first
stage. However, some European stocks such as Volkswagen performed well as
restructuring gathered pace. Growth in continental Europe remained weak
relative to the United States and the United Kingdom, and there appears to be
little need for interest rates to rise in the near term.

     In the United Kingdom, the strength of sterling hit some exporters,
resulting in lower profits. The economy remained robust, and interest rates we
believe are set to continue their upward trend to offset inflation. The market
is likely to experience some volatility following the new Labor Party's first
budget, which is expected to detail the proposed windfall tax on privatized
utilities.

     As an asset class, emerging markets performed well over the past 12
months, although Southeast Asia severely underperformed Latin America and
Eastern Europe. Structural imbalances have led to sharp falls in markets such
as Korea and Thailand. On the other hand, markets such as Brazil, Mexico,
Russia, and Egypt, driven by significant shifts in their economic policies and
relative political stability, have moved smartly higher.

For the 12 months ended May 31, 1997, Class A shares of the Fund provided a
total return of 16.43%, Class B shares 15.87%, Class C shares 15.97%, and Class
I shares 16.67%. These returns assume the reinvestment of distributions but
exclude the effects of any sales charges and compare to a 10.90% return for the
Lipper Emerging Markets Funds Index (the Lipper Index) and to a 7.76% return
for the Morgan Stanley Capital International (MSCI) Emerging Markets Free (EMF)
Index. The Lipper mutual fund indices are unmanaged indices of the largest
qualifying mutual funds within their respective investment objectives, adjusted
for the reinvestment of capital gains distributions and income dividends, while
the MSCI EMF Index is a broad, unmanaged, market-capitalization-weighted index
of equities in emerging markets. It is not possible to invest directly in an
index.

     Emerging markets have shown much better performance over the past year
after a generally poor performance in 1994 and 1995. The Fund has outperformed
the MSCI EMF Index by having above-index weightings in most of Latin America,
including Brazil, Mexico, Colombia, and Peru, and below-index weightings in
Korea and South Africa. The Fund has outperformed the Lipper Index primarily
due to its higher weightings in Brazil, Mexico, Colombia, Russia, Egypt, and
Morocco and its lower weightings in Malaysia, Indonesia, Thailand, and the
Philippines.

     The Fund remains well diversified at the country level, with major
industry weightings in telecommunications, banking, electric utilities, and
food and beverages. The largest country weightings are Brazil, Mexico, Hong
Kong, and India. Within Asia, we have sold most of our investments in Thailand,
Korea, the Philippines, and Indonesia, preferring instead Hong Kong, which is
being re-rated upward as the handover to China in mid-1997 approaches. We also
remain positive on India due to improving domestic liquidity and falling
interest rates. Elsewhere in Asia, we remain cautious, given our concern that
structural imbalances in that region's economies may continue to have a
negative impact on their stock markets.

     We remain, on the whole, positive on other emerging market countries. Our
largest position in Latin America remains in Brazil, where interest rates have
been easing steadily and reforms are continuing while the stock market
continues to rise on the back of strong earnings growth. We are also positive
on the smaller Latin American markets of Colombia and Peru. In Colombia,
political worries have overshadowed what we believe are an improving inflation
environment and very attractive valuations. In Peru, economic growth is among
the best in the region, while valuations remain among the lowest.

     In other emerging markets, Russia, Egypt, Portugal, and Greece deserve
special mention. Russia was among the best-performing markets in the world in
1996 and continues to move strongly higher in 1997, primarily due to continued
liberalization at the political and company level. The Egyptian economy is the
strongest in the Middle East as a result of efforts by the current
administration to introduce large-scale privatization of state-run companies.
Portugal has demonstrated over the past 12 months that its management of its
economy is among the best in western Europe. This has been validated by the
MSCI, which recently announced that Portugal's stock market will be in its
developed, rather than emerging market, index series beginning in December
1997. Greece is another country that has decided on an accelerated reform
program following


                                                                               3

the landslide victory by Prime Minister Simitis in September last year, which
has led to inflation and interest rates. Having been cautious on the South
African stock market for most of the past year, we are now seeing some value
there following the sharp fall of the rand and the likely peaking in inflation
and interest rates.

     Looking forward, we would expect to build up positions in South Africa and
will be monitoring our underweighted position in Asia very closely for signs of
a turn. Our positive stance toward Latin America is likely to be maintained,
although some trimming back of positions may be appropriate later this year.

For the 12 months ended May 31, 1997, Class A shares of the Fund provided a
total return of 2.88%, Class B shares 2.33%, Class C shares 2.61%, and Class I
shares 2.88%. These returns assume the reinvestment of distributions but
exclude the effects of any sales charges and compare to a 15.56% return for the
Lipper International Funds Index and to a 6.24% return for a blend (70% and
30%) of the unmanaged MSCI EAFE (Europe, Australia, Far East) Index and the
J.P. Morgan Global Bond Index (the Morgan Index). The EAFE Index is an
unmanaged index of international stocks, while the Morgan Index is an unmanaged
index of bonds issued from 13 countries with remaining maturities of at least
one year.

     The major feature in international markets over the past year was the
strength of the dollar, particularly against the Japanese yen, the German mark,
and the French franc. In January, half of the yen exposure and three-quarters
of the mark and franc exposures were hedged into dollars. Stronger growth in
the United States, weakness in the Japanese economy, and uncertainties in
Europe concerning EMU supported a stronger dollar, and we expect this dollar
strength to continue.

     The performance of Japanese equities during this period was a good
illustration of the current three-tier market: the international "nifty fifty"
blue chips such as Canon and TDK, which outperformed the market; the heavily
sold-off cyclicals; and the underperforming financial services sector. Japanese
blue-chip stocks were the main beneficiaries of the weak Japanese currency,
with many reaching all-time highs. The Fund held several of these stocks and
benefited from this upswing. Going forward, we expect the "nifty fifty" stocks
to continue to do well.

     The U.K. market performed well, and sterling remained strong despite the
prospect of a left-wing victory in the general election. Economic growth was
strong, and the interest-rate cycle has turned. However, companies with high
overseas earnings are beginning to feel the effects of the strong currency, and
profit warnings are starting to come through. We believe that the portfolio
should benefit from the mini-consumer boom likely to be generated by the
windfalls resulting from the public offerings of several building societies
(savings and loans). However, the market is likely to experience some
uncertainty following Labor's first budget in July.

     Economic growth and the equity markets in continental Europe continued to
be affected by fiscal restraint as member states struggled to meet the
Maastricht criteria. In France, an unexpected general election was called for
late May/early June. This was a gamble by the French President, Jacques Chirac,
in the vain hope that a right-wing government would be returned with a
sufficient majority to push through the economic policies necessary for
monetary union. In Germany, a row erupted between the government and the
Bundesbank over revaluation of gold reserves that might be used to reduce the
budget deficit. This led to accusations of financial dishonesty and increased
the chance that some of the weaker European countries, such as Italy, would be
included in the first round of EMU. The outlook for Europe remains uncertain,
with political upheavals, high unemployment, and EMU concerns on the horizon.
     Asian markets have shown a mixed performance over the past year. Hong Kong
has performed well due to positive sentiment over the imminent handover to
China. Other markets, however, have not performed as well due to worries over
high valuation levels.


                                                                               5

     The fixed-income portion of the Fund reflects a neutral weighting among
Europe, Japan, the United States, and the other dollar-bloc countries. U.S.
interest rates appear increasingly attractive from a global perspective. Hence,
we anticipate increasing the weighting in the dollar bloc relative to Europe
once the pickup in core European growth is confirmed and the U.S. market
adjusts to the Federal Reserve Board's tighter policy. In the meantime, we are
maintaining a defensive posture with respect to duration, or interest-rate
sensitivity, in both the dollar bloc and Europe.
     The Fund remains overweighted in Australian bonds because we believe
current yield spreads reflect undue fears of a rate hike. Within Europe,
several potential developments suggest possible opportunities: the return of
the single-currency theme to the market, which would help potential entrants
such as Ireland and Spain; the likelihood of interest-rate cuts in Italy,
Spain, and possibly Sweden; and a more attractive U.K. market following the
election and moderate interest-rate hikes. Despite extremely low absolute
yields, the Japanese bond market should be well supported by accommodative
monetary policy and domestic institutional flows. Although some of the forces
pushing the dollar up are waning, we believe it should remain firm due to
capital inflows induced by favorable interest rates and moderate growth.

For the 12 months ended May 31, 1997, Class A shares of the Fund provided a
total return of 2.13%, Class B shares 1.56%, Class C shares 1.82%, and Class I
shares 2.31%. These returns assume the reinvestment of distributions but
exclude the effects of any sales charges and compare to a 15.56% return for the
Lipper International Funds Index and to a 7.88% return for the unmanaged MSCI
EAFE Index.

     The Fund's exposure to smaller companies was reduced over the past 12
months, from 45% of assets to just over 30%. The money raised from this
asset-allocation shift was reinvested into blue-chip stocks. With liquidity
driving equity markets and deregulation and restructuring gathering pace, we
felt that blue chips would benefit more than smaller companies. Investors tend
to focus on larger, more liquid stocks when trying to invest large sums of
money, and restructuring tends to benefit larger companies with more room to
cut costs. During January, half of the Japanese yen exposure and three-quarters
of the German mark and French franc exposures were hedged into U.S. dollars.
Stronger growth in the United States, weakness in the Japanese economy, and
uncertainties in Europe concerning EMU all supported a strong dollar.

     The Fund's weighting in Japan is similar to that of other funds in its
Lipper universe. Japanese blue-chip stocks with overseas exposure such as Canon
and TDK, both held in the Fund, continue to set all-time highs due to the yen's
weakness. The Fund's weighting in smaller Japanese companies has been reduced.
These companies continue to suffer from weak investor sentiment and, being
domestically oriented, have failed to benefit from the weak currency.

     In the United Kingdom, we believe economic fundamentals remain strong,
although interest rates will almost certainly have to rise in the second or
third quarter in order to head off inflation. This, together with uncertainties
regarding the new government, the impact of a strong sterling on corporate
earnings, and volatility in the European and U.S. markets, may impact equities
in the short term. One of the best-performing sectors in the U.K. market has
been the banking sector. The Fund owns shares in Lloyds Bank, which is a
quality company with the fastest earnings growth in the sector and one of the
most profitable banks in the world. This stock is also benefiting from the
technical squeeze in the banking sector as index funds scramble to increase
their weightings in banks ahead of the public offerings of several building
societies (savings and loans).

     Within continental Europe, growth remains weak relative to the United
States and the United Kingdom, and we see little need for interest rates to
rise in the near term. Worries over EMU continue, with the major concern being
whether or not it can proceed on time and in what form. Meanwhile, corporate
restructuring in Germany is beginning to gather pace. Volkswagen, a company
held in the Fund, has re-engineered its manufacturing process and can now
produce its main model, the VW Golf, in 17 hours, compared with the 34 hours it
used to take. All Volkswagen models are now produced from only four platforms,
which has significantly reduced costs.


                                                                               7

     The Fund continues to have a sizable exposure to emerging markets, with a
tilt toward Latin America. Brazil is our favored market due to falling
inflation rates and structural changes in the telecommunications sector, in
which Telebras is a core holding. The Fund has also benefited from its exposure
to Eastern Europe, where the Russian economy, in particular, has moved sharply
upwards.

**The Consumer Price Index is published by the U.S. Bureau of Labor Statistics
  and measures the cost of living (inflation).

All results are historical and assume the reinvestment of dividends and capital
gains. Investment return and principal value will fluctuate, and shares, when
redeemed, may be worth more or less than their original cost. Past performance
is no guarantee of future results.

Performance Summary - continued

Class A share SEC results include the maximum 4.75% sales charge. Class B share
SEC results reflect the applicable contingent deferred sales charge (CDSC),
which declines over six years as follows: 4%, 4%, 3%, 3%, 2%, 1%, 0%. Class C
shares have no initial sales charge but, along with Class B shares, have higher
annual fees and expenses than Class A shares. Class C share purchases are
subject to a 1% CDSC if redeemed within 12 months of purchase. Class I shares,
which became available on January 2, 1997, have no sales charge or Rule 12b-1
fees and are only available to certain institutional investors.

Class C share results include the performance and the operating expenses (e.g.,
Rule 12b-1 fees) of the Fund's Class B shares for periods prior to the
commencement of offering of Class C shares. Operating expenses attributable to
Class C shares are not significantly different than those of Class B shares.
The Class B share performance included in the Class C share SEC performance has
been adjusted to reflect the CDSC generally applicable to Class C shares rather
than the CDSC generally applicable to Class B shares.

Class I share results include the performance and the operating expenses (e.g.,
Rule 12b-1 fees) of the Fund's Class A shares for periods prior to the
commencement of offering of Class I shares. Because operating expenses
attributable to Class A shares are greater than those of Class I shares, Class
I share performance generally would have been higher than Class A share
performance. The Class A share performance included in the Class I share
performance has been adjusted to reflect the fact that Class I shares have no
initial sales charge.

Performance results reflect any applicable expense subsidies and waivers,
without which the results would have been less favorable. Current subsidies and
waivers may be discontinued at any time.

All results are historical and assume the reinvestment of dividends and capital
gains. Investment return and principal value will fluctuate, and shares, when
redeemed, may be worth more or less than their original cost. Past performance
is no guarantee of future results.

Performance Summary - continued

Class A share SEC results include the maximum 4.75% sales charge. Class B share
SEC results reflect the applicable contingent deferred sales charge (CDSC),
which declines over six years as follows: 4%, 4%, 3%, 3%, 2%, 1%, 0%. Class C
shares have no initial sales charge but, along with Class B shares, have higher
annual fees and expenses than Class A shares. Class C share purchases are
subject to a 1% CDSC if redeemed within 12 months of purchase. Class I shares,
which became available on January 2, 1997, have no sales charge or Rule 12b-1
fees and are only available to certain institutional investors.

Class C share results include the performance and the operating expenses (e.g.,
Rule 12b-1 fees) of the Fund's Class B shares for periods prior to the
commencement of offering of Class C shares. Operating expenses attributable to
Class C shares are not significantly different than those of Class B shares.
The Class B share performance included in the Class C share SEC performance has
been adjusted to reflect the CDSC generally applicable to Class C shares rather
than the CDSC generally applicable to Class B shares.

Class I share results include the performance and the operating expenses (e.g.,
Rule 12b-1 fees) of the Fund's Class A shares for periods prior to the
commencement of offering of Class I shares. Because operating expenses
attributable to Class A shares are greater than those of Class I shares, Class
I share performance generally would have been higher than Class A share
performance. The Class A share performance included in the Class I share
performance has been adjusted to reflect the fact that Class I shares have no
initial sales charge.

Performance results reflect any applicable expense subsidies and waivers,
without which the results would have been less favorable. Current subsidies and
waivers may be discontinued at any time.

Performance Summary - continued

Class A share SEC results include the maximum 4.75% sales charge. Class B share
SEC results reflect the applicable contingent deferred sales charge (CDSC),
which declines over six years as follows: 4%, 4%, 3%, 3%, 2%, 1%, 0%. Class C
shares have no initial sales charge but, along with Class B shares, have higher
annual fees and expenses than Class A shares. Class C share purchases are
subject to a 1% CDSC if redeemed within 12 months of purchase. Class I shares,
which became available on January 2, 1997, have no sales charge or Rule 12b-1
fees and are only available to certain institutional investors.

Class C share results include the performance and the operating expenses (e.g.,
Rule 12b-1 fees) of the Fund's Class B shares for periods prior to the
commencement of offering of Class C shares. Operating expenses attributable to
Class C shares are not significantly different than those of Class B shares.
The Class B share performance included in the Class C share SEC performance has
been adjusted to reflect the CDSC generally applicable to Class C shares rather
than the CDSC generally applicable to Class B shares.

Class I share results include the performance and the operating expenses (e.g.,
Rule 12b-1 fees) of the Fund's Class A shares for periods prior to the
commencement of offering of Class I shares. Because operating expenses
attributable to Class A shares are greater than those of Class I shares, Class
I share performance generally would have been higher than Class A share
performance. The Class A share performance included in the Class I share
performance has been adjusted to reflect the fact that Class I shares have no
initial sales charge.

Performance results reflect any applicable expense subsidies and waivers,
without which the results would have been less favorable. Current subsidies and
waivers may be discontinued at any time.

Notes to Financial Statements

(1) Business and Organization

MFS/Foreign & Colonial Emerging Markets Equity Fund (Emerging Market Equity),
MFS/Foreign & Colonial International Growth and Income Fund (International
Growth and Income), and MFS/Foreign & Colonial International Growth Fund
(International Growth) (the Funds) are each a diversified series of MFS Series
Trust X (the Trust). The Trust is organized as a Massachusetts business trust
and is registered under the Investment Company Act of 1940, as amended, as an
open-end management investment company.

(2) Significant Accounting Policies

General - The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. 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 listed on securities exchanges or
reported through the NASDAQ system are valued at last sale prices. Unlisted
equity securities or listed equity securities for which last sale prices are
not available are valued at last quoted bid prices. Debt securities (other than
short-term obligations which mature in 60 days or less), including listed
issues and forward contracts, are valued on the basis of valuations furnished
by dealers or by a pricing service with consideration to factors such as
institutional-size trading in similar groups of securities, yield, quality,
coupon rate, maturity, type of issue, trading characteristics, and other market
data, without exclusive reliance upon exchange or over-the-counter prices.
Short-term obligations, which mature in 60 days or less, are valued at
amortized cost, which approximates market value. Non-U.S. dollar denominated
short-term obligations are valued at amortized cost as calculated in the base
currency and translated into U.S. dollars at the closing daily exchange rate.
Future contracts, options, and options on futures contracts listed on
commodities exchanges are valued at closing settlement prices. Over-the-counter
options are valued by brokers through the use of a pricing model which takes
into account closing bond valuations, implied volatility, and short-term
repurchase rates. Securities for which there are no such quotations or
valuations are valued at fair value as determined in good faith by or at the
direction of the Trustees.

Repurchase Agreements - The Funds may enter into repurchase agreements with
institutions that the Funds' investment adviser has determined are
creditworthy. Each repurchase agreement is recorded at cost. The Funds require
that the securities purchased in a repurchase transaction be transferred to the
custodian in a manner sufficient to enable the Funds 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 securities transferred to ensure that the
value, including accrued interest, of the securities under each repurchase
agreement is greater than amounts owed to the Funds under each such repurchase
agreement.

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 Organization Expenses - Costs incurred by the Funds in connection with
their organization have been deferred and are being amortized on a
straight-line basis over a five-year period beginning on the date of
commencement of operations of the Funds.

Written Options - The Funds may write covered call or put options for which
premiums are received and are recorded as liabilities, and are subsequently
adjusted to the current value of the options written. Premiums received from
writing options which expire are treated as realized gains. Premiums received
from writing options which are exercised or are closed are offset against the
proceeds or amount paid on the transaction to determine the realized gain or
loss. If a put option is exercised, the premium reduces the cost basis of the
security purchased by the Funds. The Funds, as writer of an option, may have no
control over whether the underlying securities may be sold (call) or purchased
(put) and, as a result, bear the market risk of an unfavorable change in the
price of the securities underlying the written option. In general, written call
options may serve as a partial hedge against decreases in value in the
underlying securities to


                                                                              35
<PAGE>

Notes to Financial Statements - continued

the extent of the premium received. Written options may also be used as part of
an income-producing strategy reflecting the view of the Funds' management on
the direction of interest rates.

Forward Foreign Currency Exchange Contracts - The Funds 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 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 Funds will enter into forward
contracts for hedging purposes as well as for non-hedging purposes. For hedging
purposes, the Funds may enter into contracts to deliver or receive foreign
currency they will receive from or require for their normal investment
activities. They 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 Funds may enter into
contracts with the intent of changing the relative exposures of the Funds'
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 for financial statement purposes as unrealized until the
contract settlement date.

Investment Transactions and Income - Investment transactions are recorded on
the trade date. Interest income is recorded on the accrual basis. All premium
and original issue discount are amortized or accreted for financial statement
and tax reporting purposes as required by federal income tax regulations.
Dividend income is recorded on the ex-dividend date for dividends received in
cash. 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.

Fees Paid Indirectly - The Funds' custodian bank calculates its fee based on
the Funds' average daily net assets. The fee is reduced according to a fee
arrangement, which provides for custody fees to be reduced based on a formula
developed to measure the value of cash deposited with the custodian by the
Funds. This amount is shown as a reduction of expenses on the Statement of
Operations.

Tax Matters and Distributions - The Funds' 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 taxable
income, including any net realized gain on investments. Accordingly, no
provision for federal income or excise tax is provided.

The Funds file a tax return annually using tax accounting methods required
under provisions of the Code which may differ from generally accepted
accounting principles, the basis on which these financial statements are
prepared. Accordingly, the amount of net investment income and net realized
gain reported on these financial statements may differ from that reported on
the Funds' tax return and, consequently, the character of distributions to
shareholders reported in the financial highlights may differ from that reported
to shareholders on Form 1099-DIV. Foreign taxes have been provided for on
interest and dividend income earned on foreign investments in accordance with
the applicable country's tax rates and to the extent unrecoverable are recorded
as a reduction of investment income. Distributions to shareholders are recorded
on the ex-dividend date.

The Fund distinguishes between distributions on a tax basis and a financial
reporting basis and requires that only distributions in excess of tax basis
earnings and profits are reported in the financial statements as a tax return
of 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 accumulated net realized
gains. During the year ended May 31, 1997, the following amounts were
reclassified due to differences between book and tax accounting for currency
transactions. These changes had no effect on the net assets or net asset value
per share.

Multiple Classes of Shares of Beneficial Interest - The Funds offer Class A,
Class B, Class C, and Class I shares. The four classes of shares differ in
their respective distribution and service fees. All shareholders bear the
common expenses of each Fund pro rata based on average daily net assets of each
class, without distinction between share classes. Dividends are declared
separately for each class. No class has preferential dividend rights;
difference in per share dividend rates are generally due to differences in
separate class expenses.

(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. The
management fee is computed daily and paid monthly at an effective annual rate
of 0.975% of average daily net assets for the International Growth Fund and the
International Growth and Income Fund, and 1.25% of average daily net assets for
the Emerging Markets Equity Fund The advisory agreements permit the adviser to
engage one or more sub-advisers and the adviser, MFS, has engaged Foreign &
Colonial Management Ltd., an England and Wales Company, to assist in the
performance of its services.

Under a temporary expense reimbursement agreement, MFS has voluntarily agreed
to pay all of the Emerging Markets Equity Fund's operating expenses, exclusive
of management, distribution, and service fees. The Emerging Markets Equity Fund
in turn will pay MFS an expense reimbursement fee not greater than 0.75% of
average daily net assets for Class A, Class B, and Class C shares. To the
extent that the expense reimbursement fee exceeds the Emerging Markets Equity
Fund's actual expenses, the excess will be applied to amounts paid by MFS in
prior years. At May 31, 1997, the aggregate unreimbursed expenses owed to MFS
by the Emerging Markets Equity Fund amounted to $38,092.

Administrator - Effective March 1, 1997, each Fund has an administrative
services agreement with MFS to provide each Fund with certain financial, legal,
compliance, shareholder communications, and other administrative services. As a
partial reimbursement for the cost of providing these services, each Fund pays
MFS an administrative fee up to 0.015% per annum of each Fund's average daily
net assets, provided that the administrative fee is not assessed on Fund assets
that exceed $3 billion.

The Funds 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 Funds from MFS. Certain of the officers
and Trustees of the Funds are officers or directors of MFS, MFS Fund
Distributors, Inc. (MFD), and MFS Service Center, Inc. (MFSC). Each of the
Funds has an unfunded defined benefit plan for all of its independent Trustees
and Mr. Bailey. Included in Trustees' compensation are net periodic pension
expenses of $1,701, $1,701, and $1,701 for the Emerging Markets Equity Fund,
International Growth and Income Fund, and International Growth Fund,
respectively, for the year ended May 31, 1997.

Distributor - MFD, a wholly owned subsidiary of MFS, as distributor, received
$44,930, $18,575, and $79,525 for the Emerging Markets Equity Fund,
International Growth and Income Fund, and International Growth Fund,
respectively, for the year ended May 31, 1997, as its portion of the sales
charge on sales of Class A shares of each Fund.

The Trustees have adopted a distribution plan for Class A, Class B, and Class C
shares of each Fund pursuant to Rule 12b-1 of the Investment Company Act of
1940 as follows:

Each Fund's distribution plan provides that the Fund will pay MFD up to 0.50%
per annum of its average daily net assets attributable to Class A 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 to each
securities dealer that enters into a sales agreement with MFD of up to 0.25%
per annum of the Fund's average daily net assets attributable to Class A shares
which are attributable to that securities dealer, a distribution fee to MFD of
up to 0.25% per annum of the Fund's average daily net assets attributable to
Class A shares, commissions to dealers, and payments to MFD wholesalers for
sales at or above a certain dollar level, and other such distribution-related
expenses that are approved by the Fund. MFD retains the service fee for
accounts not attributable to a securities dealer which amounted to $15,111,
$6,002, and $28,940 for the Emerging Markets Equity Fund, International Growth
and Income Fund, and International Growth Fund, respectively, for the year
ended May 31, 1997. Fees incurred under each Fund's distribution plan during
the year ended May 31, 1997, were 0.50% of average daily net assets
attributable to Class A shares on an annualized basis.

Each Fund's distribution plan provides that the Fund will pay MFD a
distribution fee of 0.75% per annum, and a service fee of up to 0.25% per
annum, of the Fund's average daily net assets attributable to Class B and Class
C shares. MFD will pay to securities dealers that enter into a sales agreement
with MFD all or a portion of the service fee attributable to Class B and Class
C shares, and will pay to such securities dealers all of the distribution fee
attributable to Class C shares. The service fee is intended to be additional
consideration for services rendered by the dealer with respect to Class B and
Class C shares. MFD retains the service fee for accounts not attributable to a
securities dealer, which amounted to $1,469, $1,835, and $5,117 for Class B
shares of the Emerging Markets Equity Fund, International Growth and Income
Fund, and International Growth Fund, respectively, for the year ended May 31,
1997 and $2, $0, and $26 for Class C shares of the Emerging Markets Equity
Fund, International Growth and Income Fund, and Interna-


                                                                              37

tional Growth Fund, respectively, for the period ended May 31, 1997. Fees
incurred under each Fund's distribution plan during the year ended May 31,
1997, were 1.00% of the Fund's average daily net assets attributable to Class B
and Class C shares, respectively, on an annualized basis.

Purchases over $1 million into Class A shares and certain purchases into
retirement plans are subject to a contingent deferred sales charge in the event
of a shareholder redemption within twelve months following such purchase. A
contingent deferred sales charge is imposed on shareholder redemptions of Class
B shares in the event of a shareholder redemption with six years of purchase. A
contingent deferred sales charge is imposed on shareholder redemptions of Class
C shares in the event of a shareholder redemption within twelve months of
purchases made on or after April 1, 1996. MFD receives all contingent deferred
sales charges. Contingent deferred sales charges for Class A shares imposed
during the year ended May 31, 1997, were $48, $11, and $1,254 for the Emerging
Markets Equity Fund, International Growth and Income Fund, and International
Growth Fund, respectively. Contingent deferred sales charges for Class B shares
imposed during the period ended May 31, 1997, were $43,118, $32,134, and
$103,091 for the Emerging Markets Equity Fund, International Growth and Income
Fund, and International Growth Fund, respectively. Contingent deferred sales
charges for Class C shares imposed during the period ended May 31, 1997, were
$1,252, $213, and $3,733 for the Emerging Markets Equity Fund, International
Growth and Income Fund, and International Growth Fund, respectively.

Shareholder Servicing Agent - MFSC, a wholly owned subsidiary of MFS, earns a
fee for its services as shareholder servicing agent. The fee is calculated as a
percentage of each Fund's average daily net assets at an effective annual rate
of 0.13%. Prior to January 1, 1997, the fee was calculated as a percentage of
the average daily net assets of each class of shares of each Fund at an
effective annual rate of up to 0.15%, up to 0.22%, and up to 0.15% attributable
to Class A, Class B, and Class C shares, respectively.

(6) Line of Credit

The Funds entered into agreements which enable them to participate with other
funds managed by MFS in an unsecured line of credit with a bank which permits
borrowings up to $400 million, collectively. Borrowings may be made to
temporarily finance the repurchase of Fund shares. Interest is charged to each
fund, based on its borrowings, at a rate equal to the bank's base rate. In
addition, a commitment fee, based on the average daily unused portion of the
line of credit, is allocated among the participating funds at the end of each
quarter. The commitment fees allocated to the Funds for the year ended May 31,
1997, were $0, $283, and $1,198 for the Emerging Markets Equity Fund,
International Growth and Income Fund, and International Growth Fund,
respectively.

(7) Financial Instruments

The Funds trade financial instruments with off-balance sheet risk in the normal
course of their investing activities in order to manage exposure to market
risks such as interest rates and foreign currency exchange rates. These
financial instruments include written options and forward foreign currency
exchange contracts. The notional or contractual amounts of these instruments
represent the investment the Funds have in particular classes of financial
instruments and do 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.

Report of Ernst & Young LLP, Independent Auditors

To the Trustees of MFS Series Trust X and Shareholders of MFS/Foreign &
Colonial International Funds:

We have audited the accompanying statements of assets and liabilities of
MFS/Foreign & Colonial Emerging Markets Equity Fund, MFS/Foreign & Colonial
International Growth and Income Fund, and MFS/Foreign & Colonial International
Growth Fund, ("the Funds") including the schedules of portfolio investments, as
of May 31, 1997, and the related statements of operations for the year then
ended, and the statements of changes in net assets and financial highlights for
the year then ended and for the period from October 24, 1995 (commencement of
operations) to May 31, 1996. These financial statements and financial
highlights are the responsibility of the Funds' 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 generally accepted auditing
standards. Those standards require that we plan and perform the audits 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 and financial highlights. Our procedures included
confirmation of securities owned as of May 31, 1997, by correspondence with the
custodian and brokers or other appropriate auditing procedures where replies
from brokers were not received. 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/Foreign & Colonial Emerging Markets Equity Fund, MFS/Foreign & Colonial
International Growth and Income Fund, and MFS/Foreign & Colonial International
Growth Fund at May 31, 1997, the results of their operations for the year then
ended, and the changes in their net assets and financial highlights for the
year then ended and for the period from October 24, 1995 (commencement of
operations) to May 31, 1996, in conformity with generally accepted accounting
principles.


                                                           /s/ Ernst & Young LLP

                  (c)    Registrant undertakes to furnish each person to whom a
prospectus is delivered with a copy of its latest annual report to shareholders
upon request and without charge.

                  (d)    Insofar as indemnification for liability arising under
the Securities Act of 1933 may be permitted to trustees, officers and
controlling persons of the Registrant pursuant to the provisions set forth in
Item 27 of this Part C, or otherwise, the Registrant has been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Act and is, therefore,
<PAGE>   102
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a trustee, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the Securities being
Registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
