- -- MFS EMERGING GROWTH  SERIES (the  "Emerging Growth Series"),  which seeks  to

   income;

- -- MFS TOTAL RETURN SERIES (the "Total Return Series"), which seeks primarily to
   provide above-average income  (compared to a  portfolio entirely invested  in
   equity  securities)  consistent with  the prudent  employment of  capital and
   secondarily to provide  a reasonable  opportunity for growth  of capital  and
   income;

- -- MFS UTILITIES SERIES (the "Utilities Series"), which seeks capital growth and
   current  income  (income  above  that  available  from  a  portfolio invested
   entirely in equity securities);

   income  by investing primarily in a professionally managed portfolio of fixed
   income securities, some of which may involve equity features;

- -- MFS WORLD GOVERNMENTS  SERIES (the "World  Governments Series"), which  seeks
   preservation and growth of capital, together with moderate current income;

- -- MFS  STRATEGIC  FIXED INCOME  SERIES (the  "Strategic Fixed  Income Series"),
   which seeks to maximize current income.

   a level of current income as  is believed consistent with prudent  investment
   risk and secondarily to protect shareholders' capital;

- -- MFS  LIMITED  MATURITY SERIES  (the "Limited  Maturity Series"),  which seeks
   primarily to provide as high a level  of current income as is believed to  be
   consistent   with  prudent   investment  risk  and   secondarily  to  protect
   shareholders' capital; and

- -- MFS MONEY MARKET SERIES  (the "Money Market Series"),  which seeks as high  a
   level  of current income as is considered consistent with the preservation of
   capital and liquidity.

SECURITIES OFFERING THE  HIGH CURRENT INCOME  SOUGHT BY THE  HIGH INCOME  SERIES
(COMMONLY  KNOWN AS "JUNK BONDS") ARE  ORDINARILY IN THE LOWER RATING CATEGORIES
OF RECOGNIZED  RATING AGENCIES  OR  ARE UNRATED  AND GENERALLY  INVOLVE  GREATER
VOLATILITY  OF PRICE  AND RISK  TO PRINCIPAL AND  INCOME THAN  SECURITIES IN THE
HIGHER RATING CATEGORIES. ACCORDINGLY, AN  INVESTMENT IN THE HIGH INCOME  SERIES
MAY NOT BE APPROPRIATE FOR ALL INVESTORS. THE EMERGING GROWTH SERIES, THE GROWTH
SERIES,  THE RESEARCH SERIES AND THE GROWTH  WITH INCOME SERIES ARE INTENDED FOR
INVESTORS WHO UNDERSTAND AND ARE WILLING TO ACCEPT THE RISKS ENTAILED IN SEEKING
LONG-TERM GROWTH OF  CAPITAL. BECAUSE  OF THEIR  INVESTMENT POLICIES  PERMITTING
INVESTMENT  IN FOREIGN  SECURITIES, INVESTMENTS IN  EACH SERIES  (EXCEPT FOR THE
LIMITED MATURITY SERIES AND THE MONEY MARKET SERIES) MAY BE SUBJECT TO A GREATER
DEGREE OF  RISK THAN  INVESTMENTS  IN OTHER  INVESTMENT COMPANIES  WHICH  INVEST
ENTIRELY IN DOMESTIC SECURITIES.
                              -------------------

  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
    EXCHANGE  COMMISSION  OR ANY  STATE SECURITIES  COMMISSION NOR  HAS THE
     SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION

(1)        The  Adviser has agreed  to bear, subject  to reimbursement, expenses  for each of  the Series' such  that a Series'
           aggregate operating expenses shall not exceed, on an annualized basis, 1.00% of the average daily net assets of  the
           Series  from November 2, 1994  through December 31, 1996, 1.25%  of the average daily net  assets of the Series from
           January 1, 1997  through December 31,  1998, and 1.50%  of the average  daily net assets  of the Series  thereafter;
           provided  however, that this obligation may be terminated or revised at any time. See "Information Concerning Shares
           of Each Series-- Expenses." Absent this expense  arrangement, "Other Expenses" and "Total Operating Expenses"  would
           be   % and   %, respectively, for each Series, based upon estimated expenses for the Series' current fiscal year.
(2)        The  Adviser has agreed to bear until December 31, 2004,  subject to reimbursement, expenses of the Series such that
           the Series' aggregate  operating expenses do  not exceed 1.00%,  on an annualized  basis, of its  average daily  net
           assets.  See  "Information Concerning  Shares of  Each  Series--Expenses." Absent  this expense  arrangement, "Other
           Expenses" and "Total Operating Expenses" would be   % and   %, respectively.
(3)        The Adviser has agreed to bear, subject to reimbursement, until December 31, 2004, expenses of the Series such  that
           the  Series' aggregate  operating expenses do  not exceed, on  an annualized basis,  0.60% of its  average daily net
           assets. See  "Information Concerning  Shares of  Each  Series--Expenses." Absent  this expense  arrangement,  "Other
           Expenses" and "Total Operating Expenses" would be   % and   %, respectively.

The  Series'  annual  operating  expenses do  not  reflect  expenses  imposed by
separate  accounts  of  Participating  Insurance  Companies  through  which   an
investment  in a series is made or their related contracts. A separate account's
expenses are disclosed in the prospectus through which the Contract relating  to
that separate account is offered for sale.

2.  INVESTMENT CONCEPT OF THE TRUST

The  Trust is an open-end, registered management investment company comprised of
the following twelve  series: Emerging  Growth Series,  Growth Series,  Research
Series,  Growth With Income Series, Total  Return Series, Utilities Series, High
Income Series, World  Governments Series,  Strategic Fixed  Income Series,  Bond
Series,  Limited  Maturity Series  and  Money Market  Series.  Each Series  is a
segregated, separately  managed  portfolio of  securities.  All of  the  Series,
except the Utilities Series, World Governments Series and Strategic Fixed Income
Series, are diversified. Additional series may be created from time to time. The
Trust  was organized as a  business trust under the  laws of The Commonwealth of
Massachusetts by a Declaration of Trust dated February 1, 1994.

The Trust currently intends to offer shares of each Series to insurance  company
separate  accounts that fund Contracts. Separate accounts may purchase or redeem
shares at  net asset  value without  any sales  or redemption  charge. Fees  and
charges imposed by a separate account, however, will affect the actual return to
the   holder  of  a  Contract.  A  separate  account  may  also  impose  certain
restrictions or limitations on the  allocation of purchase payments or  Contract
value  to one or more Series, and not  all Series may be available in connection
with a particular Contract. Prospective investors should consult the  applicable
Contract  prospectus for information regarding fees and expenses of the Contract
and separate account and any  applicable restrictions or limitations. The  Trust
assumes no responsibility for such prospectuses.

Shares  of  the Series  are offered  to the  separate accounts  of Participating
Insurance Companies  that are  affiliated  or unaffiliated  ("shared  funding").
Shares  of the Series may serve as  the underlying investments for both variable
annuity  and  variable  life  insurance  contracts  ("mixed  funding").  Due  to
differences  in tax treatment or other  considerations, the interests of various
Contract owners might at some time be in conflict. The Trust currently does  not
foresee  any such conflict. Nevertheless, the Trust's Trustees intend to monitor
events in  order to  identify any  material irreconcilable  conflicts which  may
possibly arise and to determine what action, if any, should be taken in response
thereto.  If such a conflict were to occur, one or more separate accounts of the
Participating Insurance Companies might be required to withdraw its  investments
in  one one  or more  Series. This might  force a  Series to  sell securities at
disadvantageous prices.

Individual Contract holders are not the "shareholders" of the Trust. Rather, the
Participating  Insurance  Companies   and  their  separate   accounts  are   the
shareholders  or  investors, although  such  companies may  pass  through voting
rights to their Contract holders.

The Trust's Board of Trustees provides broad supervision over the affairs of the
Trust and  the  Series. Massachusetts  Financial  Services Company,  a  Delaware
corporation  ("MFS" or the "Adviser"), is the investment adviser to each Series.
A majority of the Trustees of the Trust are not affiliated with the Adviser. The
Adviser is responsible for the management of  the assets of each Series and  the
officers  of the Trust  are responsible for the  operations. The Adviser manages
the Series'  portfolios  from day  to  day  in accordance  with  the  investment
objectives and policies of each Series. The selection of investments and the way
they  are managed  depend on the  conditions and  trends in the  economy and the
financial marketplaces.

4.  INVESTMENT OBJECTIVES AND POLICIES

Each  Series  has  different  investment  objectives  which  it  pursues through
separate investment policies, as described below. The differences in  objectives
and policies among the Series can be expected to affect the degree of market and
financial  risk to which each  Series is subject and  the return of each Series.
The investment  objectives and  policies of  each Series  may, unless  otherwise
specifically  stated, be changed by the Trustees  of the Trust without a vote of
the shareholders. Any investment  involves risk and there  is no assurance  that
the objectives of any Series will be achieved.

                                       6
<PAGE>
MFS  EMERGING GROWTH SERIES --  The Series seeks to  provide long-term growth of
capital. Dividend  and interest  income from  portfolio securities,  if any,  is
incidental to the Fund's investment objective of long-term growth of capital.

The  Series' policy  is to invest  primarily (I.E.,  at least 80%  of its assets
under normal circumstances) in common stocks of small and medium-sized companies
that are early in their life cycle but which have the potential to become  major
enterprises  (emerging  growth  companies). Such  companies  generally  would be
expected to show earnings growth over time that is well above the growth rate of
the overall economy  and the  rate of inflation,  and would  have the  products,
management  and market opportunities which are  usually necessary to become more
widely recognized as growth companies.

However, the Series may also invest in more established 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.

While the Series will invest  primarily in common stocks,  the Series may, to  a
limited  extent, seek appreciation in other  types of securities such as foreign
or convertible securities and warrants when relative values make such  purchases
appear  attractive  either as  individual issues  or as  types of  securities in
certain economic environments  (see "Additional Risk  Factors"). The Series  may
also  enter into forward foreign currency exchange contracts for the purchase or
sale  of  foreign  currency  for  hedging  purposes  and  non-hedging  purposes,
including   transactions  entered  into  for   the  purpose  of  profiting  from
anticipated changes in foreign  currency exchange rates, as  well as options  on
foreign  currencies (see  "Investment Techniques-- Forward  Contracts on Foreign
Currency" and "--Options on Foreign Currencies" below). The Series may also hold
foreign currency (see "Additional Risk Factors" below). The Series may invest up
to 25%  of  its total  assets  in  foreign securities  (not  including  American
Depositary  Receipts ("ADRs")),  which may be  traded on  foreign exchanges. The
Series may hold cash equivalents or other forms of debt securities as a  reserve
for future purchases of common stock or to meet liquidity needs.

The Series may invest in 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. Although ADRs are
issued by a U.S. depository,  they are subject to many  of the risks of  foreign
securities  such as  exchange rates and  more limited  information about foreign
issuers. (See "Additional Risk Factors" below).

The Series  may invest  in corporate  asset-backed securities  (see  "Investment
Techniques--Corporate  Asset-Backed  Securities"  below). The  Series  may write
covered call and put options and purchase call and put options on securities and
stock indices in an effort to  increase current income and for hedging  purposes
(see  "Investment Techniques--Options" below). The  Series may also purchase and
sell stock index futures  contracts and may write  and purchase options  thereon
for  hedging purposes  and for non-hedging  purposes, subject  to applicable law
(see "Investment Techniques--Futures Contracts and Options on Futures Contracts"
below).  In  addition,  the  Series  may  purchase  portfolio  securities  on  a
"when-issued"    or   on   a   "forward   delivery"   basis   (see   "Investment
Techniques--When-Issued Securities" below). The Series may also invest a portion
of  its  assets  in  "loan  participations"  (see  "Investment  Techniques--Loan
Participations" below).

While  it is not generally the Series'  policy to invest or trade for short-term
profits, the Series may dispose of a portfolio security whenever the 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. Subject to tax requirements, 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.

The nature of investing in emerging growth companies involves greater risk  than
is  customarily  associated  with  investments  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 growth companies or  the market averages in  general. Shares of  the
Series,  therefore, are subject to greater fluctuation in value than shares of a
conservative equity fund or  of a growth fund  which invests entirely in  proven
growth stocks.

                                       7
<PAGE>
The Series may invest to a limited extent in lower rated fixed income securities
or  comparable  unrated securities  (see  "Additional Risk  Factors--Lower Rated
Bonds" below).

MFS GROWTH  SERIES --  The Growth  Series' investment  objective is  to  provide
long-term growth of capital and future income rather than current income.

The Growth Series' policy is to invest, under normal market conditions, at least
65%  of its assets in  the common stocks, or  securities convertible into common
stocks, of  companies believed  to  possess better  than average  prospects  for
long-term   growth.  Emphasis  is  placed   on  the  selection  of  progressive,
well-managed companies.

The Series currently intends to invest in only those convertible securities that
are "investment grade" rated Baa or better by Moody's or BBB or better by S&P or
by Fitch or securities which  the Adviser believes to  be of similar quality  to
"investment  grade" securities. However, the Series  retains the right to invest
in convertible bonds that are in the  lower rated categories (rated Ba or  lower
by  Moody's or BB or lower  by S&P or by Fitch)  or securities which the Adviser
believes to be  of similar  quality to  these lower  rated securities  (commonly
known  as "junk bonds").  For a description  of bond ratings,  see Appendix B to
this Prospectus.

The Growth Series  may invest  in ADRs  and may invest  up to  30% (and  expects
generally  to  invest between     % and     %)  of its  total assets  in foreign
securities, including  emerging markets  securities (not  including ADRs).  (See
"Investment  Techniques" and "Additional Risk Factors" below.) The Growth Series
also may  purchase portfolio  securities on  a "when-issued"  or on  a  "forward
delivery"  basis. In addition, the Growth Series  may write covered call and put
options and purchase  call and put  options on securities  and stock indices  as
well as "yield curve" options. The Series may also purchase and sell stock index
and  foreign  currency  futures contracts  and  may write  and  purchase options
thereon (see "Investment Techniques" below).

The Growth Series may enter into forward foreign currency exchange contracts and
options on foreign  currencies (see "Investment  Techniques" below). The  Series
may  hold foreign  currency received in  connection with  investments in foreign
securities or in anticipation of purchasing foreign securities. (See "Additional
Risk Factors" below).

MFS RESEARCH SERIES -- The Research  Series' investment objective is to  provide
long-term growth of capital and future income.

The  portfolio securities of the Research  Series are selected by the investment
research analysts  in the  Equity Research  Group of  the Adviser.  The  Series'
assets are allocated to economic sectors (E.G. health care, technology, consumer
staples),  and then  to industry  groups within  these sectors  (E.G. within the
health care sector, the managed care,  drug and medical supply industries).  The
allocation  by sector and industry is determined by the analysts acting together
as a group.  Individual analysts are  then responsible for  selecting what  they
view  as the best  securities for capital appreciation  and future income within
their assigned industries.

The Research Series' policy is to invest a substantial proportion of its  assets
in  the common stocks or securities  convertible into common stocks of companies
believed to  possess  better than  average  prospects for  long-term  growth.  A
smaller   proportion  of  the  assets  may  be  invested  in  bonds,  short-term
obligations, preferred stocks or common stocks whose principal characteristic is
income  production  rather   than  growth.  Such   securities  may  also   offer
opportunities  for growth  of capital  as well  as income.  In the  case of both
growth stocks  and  income  issues,  emphasis is  placed  on  the  selection  of
progressive,   well-managed   companies.   The   Series'   non-convertible  debt
investments, if any, may consist of "investment grade" securities (rated Baa  or
better  by Moody's or BBB or better by S&P or by Fitch), and, with respect to no
more than 10% of  the Series' assets, securities  in the lower rated  categories
(rated  Ba or lower by Moody's or BB or  lower by S&P or by Fitch) or securities
which the  Adviser  believes to  be  of similar  quality  to these  lower  rated
securities  (commonly known  as "junk  bonds"). No more  than 5%  of the Series'
convertible securities, if any,  will consist of securities  in the lower  rated
categories  (rated Ba or lower by Moody's or BB  or lower by S&P or by Fitch) or
securities which the Adviser  believes to be of  similar quality to these  lower
rated  securities. For  a description  of bond ratings,  see Appendix  B to this
Prospectus. It is not the

                                       8
<PAGE>
Series' policy  to rely  exclusively  on ratings  issued by  established  credit
rating  agencies but  rather to supplement  such ratings with  the Adviser's own
independent and ongoing review of credit quality. The Series' achievement of its
investment objective may be more dependent on the Adviser's own credit  analysis
than  in the case  of a fund  investing in primarily  higher quality bonds. From
time to time, the Series' management will exercise its judgment with respect  to
the  proportions invested in growth  stocks, income-producing securities or cash
(including foreign currency) and cash equivalents depending on its view of their
relative attractiveness.

The Research  Series may  invest in  ADRs and  also may  invest up  to 20%  (and
expects  generally to invest between   % and   %) of its total assets in foreign
securities (not  including  ADRs). (See  "Additional  Risk Factors"  below).  In
addition,  the Research Series may enter  into forward foreign currency exchange
contracts. (See "Investment Techniques" below). The Series may also hold foreign
currency received in  connection with  investments in foreign  securities or  in
anticipation  of purchasing  foreign securities. (See  "Additional Risk Factors"
below).

The Research Series may  purchase securities that are  not registered under  the
Securities Act of 1933 (the "1933 Act"), including those that can be offered and
sold to "qualified institutional buyers" under Rule 144A under the 1933 Act.

MFS  GROWTH  WITH INCOME  SERIES --  The Growth  With Income  Series' investment
objectives are  to provide  reasonable current  income and  long-term growth  of
capital and income.

Under  normal market  conditions, the Growth  With Income Series  will invest at
least 65% of its assets in  common stocks or securities convertible into  common
stocks  that are believed to have long-term prospects for growth and income. The
Series currently  intends  to invest  in  convertible securities  only  if  such
securities  are "investment  grade" (rated  Baa or better  by Moody's  or BBB or
better by  S&P or  Fitch) or  securities which  the Adviser  believes to  be  of
similar  quality to "investment grade" securities.  The Series retains the right
to invest  in convertible  securities that  are in  the lower  rated  categories
(rated  Ba or lower by Moody's or BB or  lower by S&P or by Fitch) or securities
which the  Adviser  believes to  be  of similar  quality  to these  lower  rated
securities  (commonly known as "junk bonds"). For a description of bond ratings,
see Appendix B to this  Prospectus. However, the Series  may hold its assets  in
cash or invest in commercial paper, repurchase agreements or other forms of debt
securities either to provide reserves for future purchases of common stock or as
a defensive measure in certain economic environments.

The  Growth With Income Series may invest in  ADRs and may also invest up to 75%
(and expects generally to invest  between   %  and   %)  of its total assets  in
foreign  securities, including emerging markets securities (not including ADRs).
The Series may hold foreign currency received in connection with investments  in
foreign  securities and in  anticipation of purchasing  foreign securities. (See
"Investment Techniques" and "Additional Risk Factors" below).

The Growth With Income Series may purchase securities on a "when-issued" or on a
"forward delivery" basis. The Series also may invest in zero coupon bonds.  (See
"Investment Techniques" below).

The  Growth  With Income  Series  may write  covered  put and  call  options and
purchase put and  call options on  securities and on  stock indices. The  Series
also  may  enter into  stock index  and foreign  currency futures  contracts and
purchase and write options  on such futures contracts.  In addition, the  Series
may  enter into forward foreign currency exchange contracts and may purchase and
write options on foreign currencies. (See "Investment Techniques" below).

MFS TOTAL RETURN SERIES -- The Total Return Series' primary investment objective
is to obtain above-average income (compared to a portfolio entirely invested  in
equity  securities) consistent with  the prudent employment  of capital, and its
secondary objective is to provide a reasonable opportunity for growth of capital
and income, since many securities offering a better than average yield may  also
possess  growth potential. Thus, in selecting  securities for its portfolio, the
Series considers each of these objectives. Generally, at least 40% of the  Total
Return Series' assets are invested in equity securities.

The  Series'  policy is  to  invest in  a  broad list  of  securities, including
short-term obligations. The list  may be diversified not  only by companies  and
industries,  but also  by type of  security. Fixed income  securities and equity
securities (which  include:  common and  preferred  stocks; securities  such  as
bonds,  warrants  or  rights that  are  convertible into  stock;  and depositary

                                       9
<PAGE>
receipts for those  securities) may  be held by  the Series.  Some fixed  income
securities  may  also have  a  call on  common stock  by  means of  a conversion
privilege or attached warrants. The Total Return Series may vary the  percentage
of  assets invested in any one type of security in accordance with the Adviser's
interpretation of  economic and  money market  conditions, fiscal  and  monetary
policy  and underlying security values. The Series' debt investments may consist
of both "investment grade" securities (rated Baa or better by Moody's or BBB  or
better  by S&P or by Fitch) and securities  that are unrated or are in the lower
rating categories (rated  Ba or lower  by Moody's or  BB or lower  by S&P or  by
Fitch)  (commonly known as  "junk bonds") including  up to 20%  of its assets in
nonconvertible fixed income securities that are in these lower rating categories
and  comparable  unrated  securities  (see  "Additional  Risk  Factors"  below).
Generally,  most  of  the Series'  long-term  debt investments  will  consist of
"investment  grade"  securities.  See  Appendix  B  to  this  Prospectus  for  a
description  of these ratings. It is not  the Series' policy to rely exclusively
on ratings issued by established credit rating agencies but rather to supplement
such ratings with  the Adviser's own  independent and ongoing  review of  credit
quality.

The  Series may also  invest in United  States government securities, including:
(1) U.S.  Treasury  obligations, which  differ  only in  their  interest  rates,
maturities and times of issuance: U.S. Treasury bills (maturities of one year or
less);  U.S. Treasury notes (maturities of one  to ten years); and U.S. Treasury
bonds (generally maturities of greater than ten years), all of which are  backed
by  the full faith and credit of the U.S. Government; and (2) obligations issued
or guaranteed  by U.S.  Government agencies,  authorities or  instrumentalities,
some  of which  are backed by  the full faith  and credit of  the U.S. Treasury,
E.G., direct  pass-through  certificates  of the  Government  National  Mortgage
Association  ("GNMA"); some of which are supported by the right of the issuer to
borrow from the U.S. Government, E.G.,  obligations of Federal Home Loan  Banks;
and  some of  which are backed  only by the  credit of the  issuer itself, E.G.,
obligations of  the  Student  Loan Marketing  Association  (collectively,  "U.S.
Government  Securities"). The  term "U.S.  Government Securities"  also includes
interests in trusts or other entities representing interests in obligations that
are backed by the full faith and credit of the U.S. Government or are issued  or
guaranteed    by   the   U.S.   Government,   its   agencies,   authorities   or
instrumentalities.

The Total Return Series may invest in ADRs and may invest up to 20% (and expects
generally to  invest between     % and     %)  of its  total assets  in  foreign
securities,  including  emerging markets  securities  (not including  ADRs). The
Series may also hold foreign currency received in connection with investments in
foreign securities or  in anticipation  of purchasing  foreign securities.  (See
"Investment Techniques" and "Additional Risk Factors" below).

The  Total Return  Series may invest  in mortgage  pass-through securities, zero
coupon bonds,  deferred  interest bonds  and  PIK  bonds. The  Series  also  may
purchase  securities on  a "when-issued"  or on  a "forward  delivery" basis. In
addition, the Series may  invest in indexed  securities, mortgage "dollar  roll"
transactions,  loan participations  and corporate  asset-backed securities. (See
"Investment Techniques" below). The Total Return Series may purchase  securities
that  are not registered under the 1933 Act, including those that can be offered
and sold to "qualified institutional buyers" under Rule 144A under the 1933 Act.
(See "Additional Risks" below).

The Total Return Series may write covered put and call options on securities and
stock indices and purchase put and call options on securities and stock indices.
The Series may also enter into "yield curve" options and may purchase and  write
options on foreign currencies. (See "Investment Techniques" below).

The  Total Return Series may enter into stock index and foreign currency futures
contracts and may purchase and write options on futures contracts. In  addition,
the  Series may  enter into  forward foreign  currency exchange  contracts. (See
"Investment Techniques" below).

MFS UTILITIES SERIES --  The Utilities Series' investment  objective is to  seek
capital  growth and current income (income above that available from a portfolio
invested entirely in equity securities).

The Utilities Series  will seek  to achieve  its objective  by investing,  under
normal  circumstances, at  least 65% (but  up to  100% at the  discretion of the
Adviser) of  its assets  in equity  and  debt securities  of both  domestic  and
foreign  companies in  the utilities  industry. Equity  securities in  which the
Series  may  invest   include  common  stocks,   preferred  stocks,   securities

                                       10
<PAGE>
convertible  into common  stocks or preferred  stocks, and  warrants to purchase
common or preferred  stocks. At least  80% of  the debt securities  held by  the
Series will be rated at the time of investment at least Baa by Moody's or BBB by
S&P  or by Fitch will be of comparable quality as determined by the Adviser (see
"Additional Risk  Factors" below).  See  Appendix B  to  this prospectus  for  a
description  of these  ratings. The  Series may also  invest in  debt and equity
securities of issuers in  other industries, as  discussed below, although  under
normal  circumstances  not  more than  35%  of  the Series'  assets  will  be so
invested. In addition, the Series may hold  a portion of its assets in cash  and
money market instruments.

Companies  in  the  utilities  industry include  (i)  companies  engaged  in the
manufacture, production,  generation,  transmission,  sale  or  distribution  of
electric,  gas or other  types of energy,  water or other  sanitary services and
(ii) companies  engaged  in telecommunications,  including  telephone,  cellular
telephones,   telegraph,  satellite,  microwave,   cable  television  and  other
communications media (but  not companies  engaged in  public broadcasting).  The
Adviser  deems a particular company  to be in the  utilities industry if, at the
time of investment, the  Adviser determines that at  least 50% of the  company's
assets or revenues are derived from one or more of those industries.

The  portion of the  Utilities Series' assets  invested in a  particular type of
utility and  in equity  or debt  securities will  vary in  light of  changes  in
interest rates, market conditions and economic conditions and other factors. The
Series  may invest in  foreign securities, including  emerging market techniques
non-dollar denominated securities, although under normal circumstances it is not
expected that more  than 35%  of the  Series' assets  will be  so invested.  The
Series also may invest in ADRs. The Series may hold foreign currency received in
connection  with  investments  in  foreign  securities  and  in  anticipation of
purchasing foreign securities. (See "Investment Techniques" and "Additional Risk
Factors" below).  For  further  information  on the  principal  sectors  of  the
utilities industry in which the Series may invest, see Appendix D.

Since  the Utilities Series' investments are concentrated in utility securities,
the value of the Series' shares will be especially affected by factors  peculiar
to  the utilities  industry, and  may fluctuate  more widely  than the  value of
shares of a fund that invests in  a broader range of industries. The rates  many
utility  companies  may charge  their customers  are controlled  by governmental
regulatory commissions  which may  result  in a  delay  in the  utility  company
passing  along increases  in costs  to its  customers. Furthermore,  there is no
assurance that regulatory authorities will, in the future, grant rate  increases
or  that such increases will  be adequate to permit  the payment of dividends on
common stocks. Many  utility companies,  especially electric and  gas and  other
energy   related  utility  companies,  are  subject  to  various  uncertainties,
including: risks of increases in fuel  and other operating costs; the high  cost
of  borrowing  to  finance  capital  construction  during  inflationary periods;
difficulty obtaining adequate returns on invested capital, even if frequent rate
increases are approved by public service commissions; restrictions on operations
and increased costs and delays as  a result of environmental and nuclear  safety
regulations;  securing  financing  for  large  construction  projects  during an
inflationary period; difficulties  of the capital  markets in absorbing  utility
debt and equity securities; difficulty in raising capital in adequate amounts on
reasonable  terms in  periods of high  inflation and  unsettled capital markets;
technological  innovations  which  may  render  existing  plants,  equipment  or
products  obsolete;  the  potential  impact of  natural  or  man-made disasters;
difficulties in obtaining natural gas for resale or fuel for electric generation
at reasonable prices; coping  with the general  effects of energy  conservation,
particularly  in light of changing policies  regarding energy; and special risks
associated with  the  construction and  operation  of nuclear  power  generating
facilities,  including  technical factors  and costs,  and the  possibility that
federal, state and municipal government authorities may from time to time review
existing  requirements  and  impose  additional  requirements.  Certain  utility
companies,  especially gas and telephone utility companies, have in recent years
been affected  by  increased  competition,  which  could  adversely  affect  the
profitability  of such  utility companies. Furthermore,  there are uncertainties
resulting from certain  telecommunications companies'  diversification into  new
domestic  and  international  businesses  as well  as  agreements  by  many such
companies linking  future  rate increases  to  inflation or  other  factors  not
directly related to the active operating profits of the enterprise.

Foreign  utility  companies  are  also  subject  to  regulation,  although  such
regulations may or may not  be comparable to those  in the U.S. Foreign  utility
companies  may be  more heavily regulated  by their  respective governments than
utilities in the U.S.

                                       11
<PAGE>
and, as in the U.S., generally are required to seek government approval for rate
increases. In addition, since many foreign  utilities use fuel that causes  more
pollution  than those used in the U.S., such utilities may be required to invest
in pollution  control equipment  to meet  any proposed  pollution  restrictions.
Foreign  regulatory systems vary from country to  country and may evolve in ways
different from regulation in the U.S.

The Utilities Series is  permitted to invest in  securities of issuers that  are
outside  the utilities  industry, although  under normal  circumstances not more
than 35% of the Series' assets will be so invested. Such investments may include
common  stocks,  debt  securities  (including  municipal  debt  securities)  and
preferred  stocks and will be selected  to meet the Series' investment objective
of both capital  growth and current  income. These securities  may be issued  by
either  U.S. or non-U.S. companies.  Some of these issuers  may be in industries
related to the  utilities industry  and, therefore,  may be  subject to  similar
risks.

Investments  outside  the utilities  industry may  also include  U.S. Government
Securities,  as  that   term  is  defined   under  "Investment  Objectives   and
Policies--MFS Total Return Series" above. When and if available, U.S. Government
securities  may be purchased at a discount  from face value. However, the Series
does not intend to hold such securities to maturity for the purpose of achieving
potential  capital  gains,  unless  current  yields  on  the  securities  remain
attractive.

The  Utilities Series  may invest in  mortgage pass-through  securities that are
U.S. Government securities  and in  zero coupon  bonds, collateralized  mortgage
obligations,  multiclass  pass-through  securities  and  corporate  asset-backed
securities. The  Series may  purchase  securities on  a  "when-issued" or  on  a
"forward  delivery" basis.  The Series  may invest  in indexed  securities whose
value is linked to foreign  currencies, interest rates, commodities, indices  or
other  financial indicators.  In addition,  the Series  may enter  into mortgage
"dollar roll" transactions. (See "Investment Techniques" below). The Series  may
purchase  securities  that are  not registered  under  the 1933  Act but  can be
offered and sold to "qualified institutional  buyers" under Rule 144A under  the
1933 Act. (See "Additional Risk Factors" below).

The  Utilities Series may write  covered call and put  options and purchase call
and put options on domestic and foreign stock indices. The Series also may enter
into futures contracts on fixed  income securities, foreign currencies,  indices
of  foreign currencies, and indices of fixed income securities. In addition, the
Series may purchase and write options on such futures contracts. The Series  may
enter  into forward  foreign currency  exchange contracts  and may  purchase and
write options on foreign currencies. The  Series also may hold foreign  currency
received in connection with investments in foreign securities or in anticipation
of purchasing foreign securities. (See "Investment Techniques" below).

MFS  HIGH INCOME SERIES -- The investment objective of the High Income Series is
to seek high current income by  investing primarily in a professionally  managed
diversified  portfolio of  fixed income  securities, some  of which  may involve
equity features. Capital growth,  if any, is a  consideration incidental to  the
Series' objective of high current income.

Fixed  income securities  offering the  high current  income sought  by the High
Income Series  normally include  those  fixed income  securities which  offer  a
current  yield above  that generally available  on debt securities  in the three
highest rating categories of the  recognized rating agencies (commonly known  as
"junk  bonds" if  rated below the  four highest categories  of recognized rating
agencies). However, since  available yields  and yield  differentials vary  over
time, no specific level of income or yield differential can ever be assured. The
dividends paid by the Series will increase or decrease in relation to the income
received  by the Series from its investments, which would in any case be reduced
by the  expenses  of  the  Series  before such  income  is  distributed  to  its
shareholders.  For a description  of these rating categories,  see Appendix B to
this Prospectus. (See "Additional Risk Factors" below).

Fixed income securities include preferred and preference stocks and all types of
debt  obligations  of  both  domestic  and  foreign  issuers,  such  as   bonds,
debentures,  notes, equipment  lease certificates,  equipment trust certificates
(including interests in trusts or other entities representing such obligations),
conditional  sales  contracts,  commercial  paper  and  obligations  issued   or
guaranteed  by  the U.S.  Government,  any foreign  government  or any  of their
respective political  subdivisions,  agencies  or  instrumentalities  (including
obligations, such as repurchase agreements, secured by instruments).

                                       12
<PAGE>
Corporate  debt securities  may bear  fixed, fixed  and contingent,  or variable
rates of  interest  and may  involve  equity  features, such  as  conversion  or
exchange  rights  or warrants  for the  acquisition of  stock of  the same  or a
different issuer; participations  based on  revenues, sales or  profits; or  the
purchase  of common stock in a unit transaction (where corporate debt securities
and common stock  are offered as  a unit). Under  normal market conditions,  not
more than 25% of the value of the total assets of the High Income Series will be
invested in equity securities, including common stocks, warrants and rights.

Fixed  income securities that the High Income  Series may invest in also include
zero coupon bonds, deferred interest  bonds, PIK bonds, collateralized  mortgage
obligations,   multiclass  pass-through   securities,  stripped  mortgage-backed
securities, mortgage pass-through securities, corporate asset-backed securities,
loan participations and  other direct  indebtedness. The Series  may enter  into
mortgage  "dollar  roll"  transactions.  In addition,  the  Series  may purchase
securities on a "when-issued" or on a "forward delivery" basis. (See "Investment
Techniques" below).  The  Series  also  may purchase  securities  that  are  not
registered  under  the  1933 Act  but  can  be offered  and  sold  to "qualified
institutional buyers" under Rule 144A under the 1933 Act. (See "Additional  Risk
Factors" below).

The  High Income Series may invest in ADRs and may invest up to 35% (and expects
generally to  invest between     % and     %)  of its  total assets  in  foreign
securities  (not including ADRs). The Series  may hold foreign currency received
in connection  with investments  in foreign  securities and  in anticipation  of
purchasing  foreign securities. The Series has authority  to invest up to 25% of
its total assets in  securities issued or guaranteed  by foreign governments  or
their agencies or instrumentalities. (See "Additional Risk Factors" below).

The  High Income Series may invest up to 40% of the value of its total assets in
each of the electric utility and telephone industries, but will not invest  more
than  25%  in  either  of  those industries  unless  yields  available  for four
consecutive weeks in the  four highest rating categories  on new issue bonds  in
such  industry (issue size  of $50 million  or more) have  averaged in excess of
105% of yields of  new issue long-term industrial  bonds similarly rated  (issue
size  of $50 million or  more) and, in the opinion  of the Adviser, the relative
return available  from  the  electric  utility or  telephone  industry  and  the
relative  risk, marketability,  quality and  availability of  securities of such
industry justifies such an investment.

When and if available,  fixed income securities may  be purchased at a  discount
from  face value. However, the  High Income Series does  not intend to hold such
securities to maturity  for the  purpose of achieving  potential capital  gains,
unless  current yields on these securities  remain attractive. From time to time
the Series may purchase securities not paying interest at the time acquired  if,
in  the opinion of  the Adviser, such  securities have the  potential for future
income or capital appreciation.

The High Income Series may write covered  put and call options and purchase  put
and call options on domestic and foreign fixed income securities. The Series may
also  enter into "yield curve" options. The Series may purchase and sell futures
contracts on fixed income securities or indices of such securities and may write
or purchase options on such futures contracts. In addition, the Series may enter
into forward foreign currency exchange contracts and may purchase and write  put
and  call options on foreign currencies. The Series may enter into interest rate
swaps, currency swaps and other types  of available swap agreements. The  Series
also   may  purchase  and  sell  caps,  floors  and  collars.  (See  "Investment
Techniques" below).

MFS WORLD  GOVERNMENTS  SERIES  --  The  World  Governments  Series'  investment
objective is to seek not only preservation, but also growth of capital, together
with moderate current income.

The World Governments Series seeks to achieve its investment objective through a
professionally   managed,   internationally  diversified   portfolio  consisting
primarily of  debt securities  and to  a lesser  extent equity  securities.  The
Series  attempts to provide  investors with an opportunity  to enhance the value
and increase the protection of their investment against inflation and  otherwise
by  taking advantage of investment opportunities in the U.S. as well as in other
countries where  opportunities  may  be  more rewarding.  It  is  believed  that
diversification  of assets  on an  international basis  decreases the  degree to
which events  in any  one country,  including the  U.S., can  affect the  entire
portfolio.  Although the percentage of the Series' assets invested in securities
issued abroad and denominated in foreign  currencies will vary depending on  the
state of the economies

                                       13
<PAGE>
of  the  principal  countries of  the  world,  their financial  markets  and the
relationship of their currencies to the U.S. dollar, under normal conditions the
Series' portfolio is internationally diversified. However, for defensive reasons
or during times of international  political or economic uncertainty or  turmoil,
most or all of the Series' investments may be in the U.S.

Under  normal  economic  and market  conditions,  at  least 80%  of  the Series'
portfolio is invested in  debt securities, such  as bonds, debentures,  mortgage
securities,  notes,  commercial paper,  obligations  issued or  guaranteed  by a
government or any of its political subdivisions, agencies or  instrumentalities,
certificates  of deposit, as well  as debt obligations which  may have a call on
common stock  by means  of a  conversion privilege  or attached  warrants.  Debt
securities  in which the Series  may invest may also  include zero coupon bonds,
mortgage   pass-through   securities,   collateralized   mortgage   obligations,
multiclass  pass-through securities and stripped mortgage-backed securities. The
Series also may enter into mortgage "dollar roll" transactions. (See "Investment
Techniques" below). The Series may  purchase securities that are not  registered
under  the 1933  Act but  can be  offered and  sold to  "qualified institutional
buyers" under  Rule 144A  under the  1933 Act.  (See "Additional  Risk  Factors"
below).

The  World  Governments  Series  may  write  covered  put  and  call  options on
securities and purchase  put and call  options. The Series  may also enter  into
"yield  curve" options.  The Series  may enter  into futures  contracts on fixed
income securities, on foreign currencies and  on indices of securities, and  may
purchase  and write options  on such futures contracts.  In addition, the Series
may enter  into  forward foreign  currency  exchange contracts  and  options  on
foreign currencies. The Series also may enter into interest rate swaps, currency
swaps and other types of available swap agreements. The Series also may purchase
and sell caps, floors and collars. (See "Investment Techniques" below).

The  World Governments Series may invest in  ADRs. The Series may also invest up
to 100% (and  expects generally between    %  and    %) of its  total assets  in
foreign  securities including  emerging market securities  (not including ADRs).
See "Investment Techniques"  and "Additional  Risk Factors"  below. The  Adviser
will determine the amount of the World Governments Series' assets to be invested
in  the United States and the amount to be invested abroad. The U.S. assets will
be invested in high quality debt securities and the remainder of the assets will
be diversified among countries where opportunities for total return are expected
to be most attractive. It is currently expected that investments within  foreign
countries  will be primarily in government  securities to minimize credit risks.
The Series  will not  invest 25%  or more  of the  value of  its assets  in  the
securities of any one foreign government. The portfolio will be managed actively
and the asset allocations modified as the Adviser deems necessary.

The  World Governments Series will purchase non-dollar securities denominated in
the currency of  countries where the  interest rate environment  as well as  the
general economic climate provide an opportunity for declining interest rates and
currency  appreciation. If  interest rates  decline, such  non-dollar securities
will appreciate in value. If the  currency also appreciates against the  dollar,
the  total investment in  such non-dollar securities  would be enhanced further.
Conversely, a rise in interest rates or decline in currency exchange rates would
adversely affect  the  Series'  return. Investments  in  non-dollar  denominated
securities  are evaluated  primarily on  the strength  of a  particular currency
against the dollar and on the interest rate climate of that country. Currency is
judged on the basis of  fundamental economic criteria (E.G., relative  inflation
levels  and  trends,  growth rate  forecasts,  balance of  payments  status, and
economic policies) as well as technical  and political data. In addition to  the
foregoing,  interest  rates  are  evaluated on  the  basis  of  differentials or
anomalies that  may  exist between  different  countries. The  Series  may  hold
foreign  currency received in connection  with investments in foreign securities
and in  anticipation of  purchasing foreign  securities. (See  "Additional  Risk
Factors" below).

The  phrase  "preservation of  capital" when  applied  to a  domestic investment
company is generally understood to imply that the portfolio is invested in  very
low  risk securities and that the major risk is loss of purchasing power through
the effects of inflation or major changes in interest rates. However, while  the
World  Governments  Series  invests in  securities  which are  believed  to have
minimal credit risk, an error of judgment in selecting a currency or an interest
rate environment could result in a loss of capital.

                                       14
<PAGE>
It is contemplated that the World Governments Series' long-term debt investments
will consist primarily of securities which are believed by the Adviser to be  of
relatively  high quality.  If after  the Series  purchases such  a security, the
quality of the security  deteriorates significantly, the  security will be  sold
only if the Adviser believes it is advantageous to do so.

MFS  STRATEGIC  FIXED  INCOME  SERIES  --  The  Strategic  Fixed  Income Series'
investment objective is to maximize current income.

The Strategic Fixed Income  Series seeks to achieve  its objective by  investing
approximately  one-third of its assets  in each of the  following sectors of the
fixed income securities markets: (i) U.S. Government securities, as that term is
defined in "Investment Objectives and  Policies--MFS Total Return Series"  above
and  related options; (ii) debt securities  issued by foreign governments, their
political subdivisions  and  other  foreign issuers;  and  (iii)  high  yielding
corporate fixed income securities, some of which may involve equity features. By
following  this investment strategy, the Series' net asset value is likely to be
more stable than that of a fund which  invests in only one of these three  fixed
income  sectors. The  Investment Adviser  believes that  greater stability would
occur because, in general, each  sector historically has produced results  which
are  different from each other sector, so that significant changes in one sector
have tended to offset changes in other sectors. During periods of unusual market
or economic conditions  (such as a  collapse of the  high yield corporate  fixed
income  market or a  general contraction in yields  on foreign obligations), the
Series may invest up to 50% of its  assets in any one sector and may choose  not
to  invest in a sector in order  to achieve its investment objective. The Series
expects that,  under normal  market conditions,  the maturity  of its  portfolio
securities  will not exceed 30 years in  the U.S. Government sector and 25 years
in the corporate fixed income sector. At  least 80% of the Series' assets  under
normal circumstances will be invested in fixed income securities.

The  Strategic  Fixed Income  Series may  invest  in ADRs.  The Series  does not
currently intend to invest over 45% (and expects generally to invest between   %
and     %) of  its  assets in  foreign  securities, including  emerging  markets
securities  (not including ADRs), but reserves the  right to invest up to 67% of
its assets in  foreign securities,  including emerging  markets securities  (not
including  ADRs), depending on market conditions. These foreign securities shall
include securities  issued  by  foreign governments  considered  stable  by  the
Investment  Adviser  and fixed  income securities  of foreign  corporations. The
foreign government  securities  in  which  the Series  intends  to  invest  will
generally  consist of obligations supported though their authority to levy taxes
by national, state or provincial governments or similar political  subdivisions.
While  one-third of the  Series' assets normally will  be invested in securities
issued abroad and denominated  in foreign currencies ("non-dollar  securities"),
that  amount may vary  depending on the  relative yield of  such securities, the
economies of the countries in which the investments are made and such countries'
financial  markets,  the  interest  rate  climate  of  such  countries  and  the
relationship  of such countries'  currencies to the  U.S. dollar. Investments in
non-dollar securities and currency will be evaluated on the basis of fundamental
economic criteria  (E.G.,  relative inflation  levels  and trends,  growth  rate
forecasts,  balance  of  payments  status, and  economic  policies)  as  well as
technical and political data. In addition  to the foregoing, interest rates  are
evaluated  on the  basis of  differentials or  anomalies that  may exist between
different countries. The Series may  hold foreign currency for hedging  purposes
to  protect against declines in the U.S. dollar value of foreign securities held
by the Series  and against increases  in the  U.S. dollar value  of the  foreign
securities  which the Series might purchase. The Series may speculate in foreign
currency when, in the judgment of the Investment 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  rate. The Series may  invest more than 25%  of
the  value  of its  total assets  in securities  of issuers  located in  any one
country. (See "Investment Techniques" and "Additional Risk Factors" below.)

High yield  corporate  fixed income  securities  of both  domestic  and  foreign
issuers  (denominated either in  U.S. dollars or foreign  currency) in which the
Strategic Fixed Income Series may invest include preferred and preference  stock
and  all  types  of  long-  or  short-term  debt  obligations,  such  as  bonds,
debentures, notes, equipment lease  certificates, equipment trust  certificates,
conditional sales contracts and commercial paper (including obligations, such as
repurchase  agreements, secured by such instruments). High yield corporate fixed
income  securities  held  by  the  Series  are  ordinarily  unrated  or  in  the

                                       15
<PAGE>
lower  rating categories  of recognized  rating agencies.  (See "Additional Risk
Factors" below.) Corporate fixed income securities may also include zero  coupon
bonds,  deferred interest bonds and PIK bonds. Corporate fixed income securities
may involve equity features, such as  conversion or exchange rights or  warrants
for  the acquisition of stock of the  same or a different issuer; participations
based on revenues, sales or profits; or  the purchase of common stock in a  unit
transaction  (where corporate debt securities and  common stock are offered as a
unit).

The Strategic  Fixed  Income  Series may  invest  in  "when-issued"  securities,
collateralized   mortgage   obligations,  multiclass   pass-through  securities,
stripped mortgage-backed  securities,  corporate asset-backed  securities,  zero
coupon  bonds, loan  participations and  other indebtedness  and may  enter into
mortgage "dollar roll"  transactions. (See "Investment  Techniques" below.)  The
Series  may purchase securities that  are not registered under  the 1933 Act but
can be offered  and sold  to "qualified  institutional buyers"  under Rule  144A
under the 1933 Act. (See "Additional Risk Factors" below.)

The  Strategic Fixed  Income Series  may write covered  put and  call options on
securities and purchase put and call options on securities. The Series may  also
enter into "yield curve" options. The Series may enter into futures contracts on
fixed  income securities, on foreign currencies  and on indices of securities or
foreign  currencies,  and  may  purchase  and  write  options  on  such  futures
contracts.  In  addition, the  Series may  enter  into forward  foreign currency
exchange contracts and options on foreign currencies. The Series may enter  into
interest   rate  swaps,  currency  swaps  and  other  types  of  available  swap
agreements. The Series also may purchase and sell caps, floors and collars. (See
"Investment Techniques" below.)

The Strategic Fixed Income Series may invest up to 40% of the value of its total
assets in each of  the electric utility and  telephone industries, but will  not
invest  more than 25% in either of  those industries unless yields available for
four consecutive weeks in the four highest rating categories on new issue  bonds
in  such industry (issue size of $50 million or more) have averaged in excess of
105% of yields of  new issue long-term industrial  bonds similarly rated  (issue
size of $50 million or more).

When  the Investment Adviser  believes that investing  for defensive purposes is
appropriate, such as during periods of unusual market conditions, part or all of
the Strategic Fixed  Income Series' assets  may be temporarily  invested in  the
instruments  set  forth under  "Short Term  Investments for  Defensive Purposes"
below as well as in foreign  government securities of at least investment  grade
level.

MFS  BOND SERIES -- The Bond Series'  primary investment objective is to provide
as high a level of current income  as is believed to be consistent with  prudent
investment  risk. The  Series' secondary  objective is  to protect shareholders'
capital.

Under normal market conditions, all of the Bond Series' investments will be made
in accordance with the following policies:

    1.  Approximately 80% of the Series' net assets will be invested in:

        (a) non-convertible debt securities which have a rating within the  four
           highest  grades as determined by S&P (AAA,  AA, A or BBB) or Fitch or
           Moody's (Aaa, Aa, A or Baa) and comparable unrated securities; for  a
           description  of  these  rating  categories, see  Appendix  B  to this
           Prospectus;

        (b) U.S. Government Securities, as defined in "Investment Objectives and
           Policies--MFS Total Return Series" above;

        (c) non-convertible debt securities issued or guaranteed by national  or
           state banks or bank holding companies (as defined in the Federal Bank
           Holding  Company Act) which, although not rated as a matter of policy
           by S&P  or  Moody's,  are  considered  by  the  Adviser  to  have  an
           investment  quality equivalent  to securities which  may be purchased
           under item (a) above; or

        (d) commercial paper,  repurchase agreements, cash  or cash  equivalents
           (such as certificates of deposit and bankers' acceptances).

    2.  Up to 20% of the Series' total assets may be invested in non-convertible
       debt securities which are not rated within the four highest grades of S&P
       or  Moody's or Fitch as described above and comparable unrated securities

                                       16
<PAGE>
        (commonly  known as "junk bonds") and in convertible debt securities and
        preferred stocks. These convertible debt securities and preferred stocks
        may be unrated or rated below the four highest grades of S&P and Moody's
        or Fitch  described  above.  For  a description  of  these  ratings  see
        Appendix  B  to  this  Prospectus.  For a  discussion  of  the  risks of
        investing in these securities, see "Additional Risks" below.

Although the Bond  Series may  purchase Canadian and  other foreign  securities,
under normal market conditions, it may not invest more than 10% of its assets in
non-dollar  denominated,  non-Canadian  foreign  securities,  including emerging
markets securities. The Series may hold foreign currency received in  connection
with  investments in foreign securities or in anticipation of purchasing foreign
securities. (See "Investment Techniques" and "Additional Risk Factors" below).

The Bond Series may not directly purchase common stocks. However, the Series may
retain up to 10% of its total assets in common stocks which were acquired either
by conversion of fixed income securities or by the exercise of warrants attached
thereto.

U.S. Government Securities also  include interests in  trusts or other  entities
representing  interests in obligations that are issued or guaranteed by the U.S.
Government, its agencies, authorities or instrumentalities.

The Bond  Series  may  invest in  corporate  asset-backed  securities,  mortgage
pass-through  securities, zero coupon bonds, deferred interest bonds, PIK bonds,
collateralized  mortgage   obligations,  multiclass   pass-through   securities,
stripped   mortgage-backed   securities,   "when-issued"   securities,   indexed
securities and mortgage "dollar roll" transactions. (See "Investment Techniques"
below). The Series  may purchase securities  that are not  registered under  the
1933  Act but can be offered and  sold to "qualified institutional buyers" under
Rule 144A under the 1933 Act. (See "Additional Risk Factors" below).

The Bond Series may write covered put and call options and purchase put and call
options on domestic  and foreign fixed  income securities. The  Series may  also
enter  into "yield curve" options. The Bond Series may purchase and sell futures
contracts on domestic  or foreign  fixed income  securities or  indices of  such
securities  as well as  options on such  futures contracts. The  Series may also
enter into forward foreign  currency exchange contracts  and options on  foreign
currency.  In addition, the Series may  enter into interest rate swaps, currency
swaps and other types of available swap agreements. The Series also may purchase
caps, floors and collars. (See "Investment Techniques" below).

MFS LIMITED MATURITY SERIES --  The Limited Maturity Series' primary  investment
objective  is to provide as high a level  of current income as is believed to be
consistent with prudent investment risk.  The Series' secondary objective is  to
protect shareholders' capital.

In  seeking to  achieve its investment  objectives, the  Limited Maturity Series
invests, under normal  market conditions,  substantially all its  assets in  the
following securities:

    1.    Debt  securities  (including  corporate  asset-backed  securities  and
       mortgage pass-through  securities discussed  below) which  have a  rating
       within  the four highest grades as determined by S&P or Fitch (AAA, AA, A
       or BBB) or Moody's (Aaa, Aa, A or Baa) and comparable unrated securities;
       for a description  of these  rating categories,  see Appendix  B to  this
       Prospectus;

    2.   U.S.  Government Securities, as  defined in  "Investment Objectives and
       Policies--MFS Total Return Series" above; or

    3.  Commercial paper, repurchase agreements, cash or cash equivalents  (such
       as certificates of deposit and bankers' acceptances).

The Limited Maturity Series will only invest in securities rated within the four
highest grades, as determined by S&P or Moody's or Fitch, and comparable unrated
securities.  In addition, the dollar weighted average quality of the Series will
be within the three highest grades, as determined by S&P or Moody's or Fitch (or
the Adviser in the case of unrated securities).

                                       17
<PAGE>
Under normal market conditions, substantially all the securities in the  Series'
portfolio  will have  remaining maturities  of five  years or  less or estimated
remaining average lives of  five years or less.  In the case of  mortgage-backed
and  corporate  asset-backed  securities  as  well  as  collateralized  mortgage
obligations, the average  life is likely  to be substantially  shorter than  the
stated final maturity as a result of unscheduled principal prepayments.

For  purposes of  the foregoing investment  policy, securities  having a certain
maturity will be deemed to include  securities with an equivalent "duration"  of
such  securities. "Duration" is  a commonly used  measure of the  longevity of a
debt instrument that takes into account the full stream of payments received  on
a  debt instrument,  including both  interest and  principal payments,  based on
their present values.  A debt  instrument's duration is  derived by  discounting
principal  and interest payments  to their present  value using the instrument's
current yield  to maturity  and taking  the dollar-weighted  average time  until
those  payments will  be received. Contractual  rights to dispose  of a security
will be considered in calculating duration because such rights limit the  period
during which the Series bears a market risk with respect to the security.

The  Limited Maturity Series may invest in U.S. Government Securities as defined
under "Investment Objectives and Policies--MFS Total Return Series" above.

The Limited  Maturity Series  may  invest up  to 25%  of  its assets  in  dollar
denominated foreign debt securities, including emerging markets securities. (See
"Investment  Techniques" and  "Additional Risk  Factors" below).  The Series may
invest in mortgage  pass-through securities, zero  coupon bonds,  collateralized
mortgage   obligations,   corporate  asset-backed   securities   and  multiclass
pass-through securities. In addition, the Series may enter into mortgage "dollar
roll" transactions  and may  purchase  securities on  a  "when-issued" or  on  a
"forward  delivery" basis. (See "Investment  Techniques" below). The Series also
may purchase securities that are  not registered under the  1933 Act but can  be
offered  and sold to "qualified institutional  buyers" under Rule 144A under the
1933 Act.

The Limited Maturity  Series may purchase  and sell futures  contracts on  fixed
income  securities or  indices of such  securities. In addition,  the Series may
enter into  interest  rate  swaps,  currency  swaps  and  other  available  swap
agreements. The Series also may purchase and sell caps, floors and collars. (See
"Investment Techniques" below).

MFS  MONEY MARKET SERIES -- The Money  Market Series' investment objective is to
seek as high  a level of  current income  as is considered  consistent with  the
preservation of capital and liquidity.

The  Money Market Series seeks to  achieve its investment objective by investing
primarily (I.E., at least 80% of  its assets under normal circumstances) in  the
following instruments:

        (a) U.S. Government Securities, as defined in "Investment Objectives and
    Policies--MFS  Total Return  Series" above  (including repurchase agreements
    collateralized by such securities);

        (b) obligations of banks (including certificates of deposit and bankers'
    acceptances) which  at the  date of  investment have  capital, surplus,  and
    undivided profits (as of the date of their most recently published financial
    statements)  in excess  of $100,000,000; and  obligations of  other banks or
    savings and loan associations if such obligations are insured by the Federal
    Deposit Insurance  Corporation,  provided that  not  more than  10%  of  the
    Series' total assets will be invested in such insured obligations;

        (c) commercial paper which at the date of investment is rated A-1 by S&P
    or  by Fitch or P-1 by Moody's or,  if not rated, is issued or guaranteed as
    to payment  of principal  and interest  by companies  which at  the date  of
    investment  have an outstanding debt  issue rated AA or  better by S&P or by
    Fitch or Aa or better  by Moody's (for a  description of these ratings,  see
    Appendix B to this Prospectus); and

        (d)  short-term (maturing  in 13  months or  less) corporate obligations
    which at the date of investment are rated AA or better by S&P or by Fitch or
    Aa or better by Moody's.

The Money Market Series may  also invest up to 20%  of its total assets in  debt
instruments  not specifically described in (a)  through (d) above, provided that
such instruments are deemed  by the Trustees  of the Trust  to be of  comparable
high  quality and liquidity and provided that such investments are in accordance
with applicable  law. The  Money Market  Series  may invest  its assets  in  the
securities  of foreign issuers and in the securities of foreign branches of U.S.
banks such  as  negotiable  certificates of  deposit  (Eurodollars).  Since  the
portfolio of the Series may contain such securities, an investment in the Series
may  involve a greater degree of risk than an investment in a fund which invests
only in debt obligations of U.S.  domestic issuers, due to the possibility  that
there  may be less  publicly available information,  more volatile markets, less
securities regulation, less favorable tax provisions, war or expropriation. (See
"Additional Risk Factors" below).

In addition, the Money Market Series may invest  up to 75% of its assets in  all
finance  companies as a group,  all banks and bank  holding companies as a group
and all utility companies as a group  when, in the opinion of management,  yield
differentials and money market conditions suggest such investments are advisable
and  when cash is  available for such investments  and instruments are available
for purchase  which  fulfill the  Series'  objective  in terms  of  quality  and
marketability.

All  the assets of the Money Market Series will be invested in obligations which
mature in 13 months or less and  substantially all of these investments will  be
held  to maturity; however, securities collateralizing repurchase agreements may
have maturities in excess  of 13 months.  The Money Market  Series will, to  the
extent  feasible, make portfolio investments primarily  in anticipation of or in
response to changing economic and money market conditions and trends. Currently,
the dollar weighted average  maturity of the investments  of the Series may  not
exceed 90 days.

5.  INVESTMENT TECHNIQUES

LENDING  OF PORTFOLIO  SECURITIES: Each of  the Series (except  the Money Market
Series) may seek to  increase its income by  lending portfolio securities.  Such
loans will usually be made to member firms (and subsidiaries thereof) of the New
York  Stock Exchange (the "Exchange") and to member banks of the Federal Reserve
System, and would be required to be secured continuously by collateral in  cash,
cash equivalents or U.S. Treasury securities maintained on a current basis at an
amount  at least  equal to  the market  value of  the securities  loaned. If the
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 total assets of
the Series making the loans.

EMERGING MARKETS SECURITIES: Each  of the Growth  With Income Series,  Utilities
Series,  Total Return Series, World Governments Series, Limited Maturity Series,
Bond Series, Strategic Fixed Income Series and Growth Series may invest in fixed
income  securities  of   issuers  (including  foreign   governments  and   their
subdivisions,  agencies or  instrumentalities) located in  emerging markets. For
the purposes of each Series, emerging markets include any country: (i) having an
"emerging stock market"  as defined  by the  International Finance  Corporation;
(ii) with low-to middle-income economies according to the International Bank for
Reconstruction  and Development  (the World  Bank); (iii)  listed in  World Bank
publications as developing; or (iv) determined  by MFS to be an emerging  market
as  defined above.  Each Series  may invest in  fixed income  securities of: (i)
foreign  governments  or  any  of  their  political  subdivisions,  agencies  or
instrumentalities;  (ii) companies  the principal securities  trading market for
which is an emerging  market country; (iii) companies  organized under the  laws
of,  and with a principal office in,  an emerging market country; (iv) companies
whose principal  activities are  located in  emerging market  countries; or  (v)
companies  whose securities are traded in any  market that derive 50% or more of
their total revenue from either goods or services produced in an emerging market
or sold in an emerging market.

REPURCHASE AGREEMENTS: Each of the  Series may enter into repurchase  agreements
in order to earn additional income on available cash or as a temporary defensive
measure.  Under a repurchase agreement, a  Series 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 Series'  right to  liquidate  the
securities  may be  restricted (during  which time  the value  of the securities
could decline). As discussed  in the Statement  of Additional Information,  each
Series has adopted certain procedures intended to minimize any risk.

                                       19
<PAGE>
"WHEN-ISSUED"  SECURITIES: Each of  the Series (except  the Research Series, the
World Governments Series and the Money Market Series) may purchase securities on
a "when-issued"  or  on  a  "forward  delivery"  basis,  which  means  that  the
securities  will be  delivered to  the Series  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. In
general, a Series does not pay for such securities until received, and does  not
start  earning interest on the securities until the contractual settlement date.
While awaiting delivery  of securities purchased  on such bases,  a Series  will
normally invest in cash, cash equivalents and high grade debt securities.

MORTGAGE  "DOLLAR ROLL" TRANSACTIONS: Each of  the Total Return Series, the Bond
Series, the Strategic  Fixed Income  Series, the World  Governments Series,  the
Limited  Maturity Series,  the High Income  Series and the  Utilities Series may
enter  into  mortgage  "dollar  roll"  transactions  with  selected  banks   and
broker-dealers  pursuant to which a  Series sells mortgage-backed securities for
delivery in the future (generally  within 30 days) and simultaneously  contracts
to  repurchase substantially similar (same type, coupon and maturity) securities
on a specified  future date.  A Series  will only  enter into  covered rolls.  A
"covered  roll"  is  a  specific type  of  dollar  roll for  which  there  is an
offsetting cash position or a cash equivalent security position which matures on
or before the  forward settlement date  of the dollar  roll transaction. In  the
event  that the  party with whom  the Series contracts  to replace substantially
similar securities on a future date fails to deliver such securities, the Series
may not  be able  to  obtain such  securities at  the  price specified  in  such
contract  and  thus may  not  benefit from  the  price differential  between the
current sales price and the repurchase price.

CORPORATE ASSET-BACKED SECURITIES: Each of the Emerging Market Series, the Total
Return Series, the  Bond Series, the  Limited Maturity Series,  the High  Income
Series, the Strategic Fixed Income Series and the Utilities Series may invest in
corporate  asset-backed  securities.  These  securities,  issued  by  trusts and
special purpose corporations,  are backed by  a pool of  assets, such as  credit
card  and automobile loan receivables, representing  the obligations of a number
of different parties.

Corporate asset-backed securities  present certain risks.  For instance, in  the
case  of credit card receivables,  these securities may not  have the benefit of
any security interest  in the  related collateral. Credit  card receivables  are
generally  unsecured and the debtors are entitled  to the protection of a number
of state and federal consumer credit laws,  many of which give such debtors  the
right  to set off certain amounts owed on the credit cards, thereby reducing the
balance due.  Most issuers  of automobile  receivables permit  the servicers  to
retain  possession of the  underlying obligations. If the  servicer were to sell
these obligations to  another party, there  is a risk  that the purchaser  would
acquire  an interest superior to  that of the holders  of the related automobile
receivables. In addition, because of the large number of vehicles involved in  a
typical  issuance and technical  requirements under state  laws, the trustee for
the holders  of  the automobile  receivables  may  not have  a  proper  security
interest in all of the obligations backing such receivables. Therefore, there is
the  possibility  that recoveries  on repossessed  collateral  may not,  in some
cases, be  available to  support payments  on these  securities. The  underlying
assets  (E.G.,  loans)  are  also  subject  to  prepayments  which  shorten  the
securities' weighted average life and may lower their return.

Corporate  asset-backed  securities  are  often  backed  by  a  pool  of  assets
representing  the obligations  of a number  of different parties.  To lessen the
effect of  failures by  obligors  on underlying  assets  to make  payments,  the
securities   may  contain  elements  of  credit  support  which  fall  into  two
categories:  (i)  liquidity  protection;  and  (ii)  protection  against  losses
resulting  from  ultimate  default  by  an  obligor  on  the  underlying assets.
Liquidity protection  refers to  the  provision of  advances, generally  by  the
entity  administering the pool of assets, to ensure that the receipt of payments
on the underlying  pool occurs in  a timely fashion.  Protection against  losses
resulting  from ultimate default  ensures payment through  insurance policies or
letters of credit obtained by the issuer or sponsor from third parties. A Series
will not pay any additional or separate  fees for credit support. The degree  of
credit  support  provided  for  each  issue  is  generally  based  on historical
information respecting the level of  credit risk associated with the  underlying
assets.  Delinquency or  loss in  excess of that  anticipated or  failure of the
credit support could  adversely affect  the return on  an investment  in such  a
security.

ZERO  COUPON BONDS,  DEFERRED INTEREST  BONDS AND PIK  BONDS: Each  of the Total
Return Series, the  Bond Series, the  Strategic Fixed Income  Series, the  World
Governments  Series, the Growth With Income Series, the Limited Maturity Series,
the High

                                       20
<PAGE>
Income Series and  the Utilities  Series may invest  in zero  coupon bonds.  The
Total  Return Series, the Bond Series and the High Income Series may also invest
in deferred interest  bonds and  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  than  debt
obligations which make  regular payments  of interest. Each  Series 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 to
satisfy the Series' distribution obligations.

COLLATERALIZED MORTGAGE OBLIGATIONS AND MULTICLASS PASS-THROUGH SECURITIES: Each
of the Bond  Series, the Strategic  Fixed Income Series,  the World  Governments
Series,  the Limited Maturity  Series, the High Income  Series and the Utilities
Series may invest a portion of its assets in collateralized mortgage obligations
or "CMOs,"  which  are debt  obligations  collateralized by  mortgage  loans  or
mortgage   pass-through  securities.  Typically,   CMOs  are  collateralized  by
certificates issued by GNMA, the Federal National Mortgage Association  ("FNMA")
or  the  Federal  Home Loan  Mortgage  Corporation  ("FHLMC"), but  also  may be
collateralized by whole loans or private mortgage pass-through securities  (such
collateral  collectively referred to as "Mortgage Assets"). Each of these Series
may also invest a  portion of its assets  in multiclass pass-through  securities
which  are interests in a trust composed of Mortgage Assets. CMOs (which include
multiclass pass-through securities)  may be issued  by agencies, authorities  or
instrumentalities  of  the  U.S. Government  or  by private  originators  of, or
investors in, mortgage loans, including savings and loan associations,  mortgage
banks,  commercial banks, investment  banks and special  purpose subsidiaries of
the foregoing. Payments of principal of and interest on the Mortgage Assets, and
any reinvestment income thereon,  provide the funds to  pay debt service on  the
CMOs  or make scheduled distributions on the multiclass pass-through securities.
In a CMO,  a series  of bonds  or certificates  are usually  issued in  multiple
classes  with different maturities. Each  class of CMOs, often  referred to as a
"tranche", is issued  at a  specific fixed  or floating  coupon rate  and has  a
stated  maturity  or  final  distribution  date.  Principal  prepayments  on the
Mortgage Assets may  cause the  CMOs to  be retired  substantially earlier  than
their  stated maturities or final distribution dates, resulting in a loss of all
or part  of the  premium if  any has  been paid.  Certain classes  of CMOs  have
priority  over  others  with  respect  to  the  receipt  of  prepayments  on the
mortgages. Therefore, depending on the type  of CMOs in which a Series  invests,
the  investment may be subject  to a greater or  lesser risk of prepayments than
other types of mortgage-related securities.

Each  of  the  Bond  Series,  the  Strategic  Fixed  Income  Series,  the  World
Governments  Series, the Limited Maturity Series, the High Income Series and the
Utilities Series may also invest in  parallel pay CMOs and Planned  Amortization
Class  CMOs ("PAC Bonds"). Parallel pay  CMOs are structured to provide payments
of principal on each payment  date to more than  one class. PAC Bonds  generally
require  payments of a specified  amount of principal on  each payment date. PAC
Bonds are always parallel pay CMOs  with the required principal payment on  such
securities  having  the highest  priority after  interest has  been paid  to all
classes. For a further description of CMOs, parallel pay CMOs and PAC Bonds  and
the  risks  related to  transactions therein,  see  the Statement  of Additional
Information.

STRIPPED MORTGAGE-BACKED  SECURITIES: Each  of the  Bond Series,  the  Strategic
Fixed Income Series, the World Governments Series and the High Income Series may
also  invest  a portion  of its  assets  in stripped  mortgage-backed securities
("SMBS"), which are derivative multiclass mortgage securities usually structured
with two classes that  receive different proportions  of interest and  principal
distributions  from  an  underlying  pool  of  mortgage  assets.  For  a further
description of  SMBS and  the risks  related to  transactions therein,  see  the
Statement of Additional Information.

                                       21
<PAGE>
LOAN  PARTICIPATIONS AND OTHER DIRECT INDEBTEDNESS:  Each of the Emerging Growth
Series, Total Return  Series, the  High Income  Series and  the Strategic  Fixed
Income  Series may invest a  portion of its assets  in "loan participations" and
other direct indebtedness. By purchasing a loan participation, a Series acquires
some or all of the interest of a bank or other lending institution in a loan  to
a  corporate 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. A Series may also  purchase other direct indebtedness such as
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 loan
participations and other direct  indebtedness acquired by  a Series may  involve
revolving  credit  facilities  or  other  standby  financing  commitments  which
obligate a Series to pay additional cash on a certain date or on demand.

The highly leveraged nature of many such loans and other direct indebtedness may
make such loans especially vulnerable to  adverse changes in economic or  market
conditions.  Loan participations and other direct indebtedness 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
Series 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 loan
participations, other direct indebtedness and the risks related to  transactions
therein, see the Statement of Additional Information.

MORTGAGE  PASS-THROUGH SECURITIES:  Each of  the Total  Return Series,  the Bond
Series, the World Governments Series, the  Limited Maturity Series and the  High
Income   Series  may  invest  in   mortgage  pass-through  securities.  Mortgage
pass-through securities  are securities  representing  interests in  "pools"  of
mortgage  loans.  The  Utilities  Series  may  invest  in  mortgage pass-through
securities that are securities issued or guaranteed as to principal and interest
by the U.S. Government, its agencies, authorities or instrumentalities.  Monthly
payments  of interest and principal by the individual borrowers on mortgages are
passed through to the holders of the securities (net of fees paid to the  issuer
or  guarantor of  the securities)  as the  mortgages in  the underlying mortgage
pools are paid  off. Payment of  principal and interest  on some mortgage  pass-
through  securities (but not the market  value of the securities themselves) may
be guaranteed by the full faith and  credit of the U.S. Government (in the  case
of  securities guaranteed by  GNMA); or guaranteed  by U.S. Government-sponsored
corporations  (such  as  FNMA  or  FHLMC,  which  are  supported  only  by   the
discretionary  authority  of  the  U.S.  Government  to  purchase  the  agency's
obligations).  Mortgage   pass-through  securities   may  also   be  issued   by
non-governmental   issuers  (such   as  commercial   banks,  savings   and  loan
institutions, private mortgage insurance  companies, mortgage bankers and  other
secondary  market issuers).  See the Statement  of Additional  Information for a
further discussion of these securities.

INDEXED SECURITIES: Each  of the Total  Return Series, High  Income Series,  the
Bond  Series and  the Utilities  Series 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 and/or interest rates rise
or fall according to the change in one or more specified underlying instruments.
Indexed securities may  include securities  that have  embedded swap  agreements
(see  "Swaps and Related Transactions"). Indexed securities may be positively or
negatively indexed (I.E., their value 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.

SWAPS AND RELATED TRANSACTIONS: As one way of managing its exposure to different
types  of investments,  each of  the High  Income Series,  the World Governments
Series, the  Strategic Fixed  Income Series,  the Bond  Series and  the  Limited
Maturity  Series 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 Series with another party of cash payments based upon
different interest rate indexes, currencies, and other prices or rates, such  as
the    value   of   mortgage    prepayment   rates.   For    example,   in   the

                                       22
<PAGE>
typical  interest rate swap, a Series 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 principal  amount
determined by the parties.

Each  of the  High Income  Series, the  World Governments  Series, the Strategic
Fixed Income Series, the  Bond Series and the  Limited Maturity Series 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 will tend to shift a  Series' investment exposure from one type
of investment to another. For example,  if a Series 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 a Series'  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. Depending on  how
they  are used, swap agreements may  increase or decrease the overall volatility
of a Series' investments and its share price and yield.

Swap agreements are sophisticated hedging  instruments that typically involve  a
small  investment  of cash  relative to  the  magnitude of  risks assumed.  As a
result, swaps can be  highly volatile and  may have a  considerable impact on  a
Series'  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 Series 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  Statement  of  Additional  Information  for  further
information on, and the risks involved in, these activities.

OPTIONS ON SECURITIES: Each of the Emerging Growth, the Growth Series, the Total
Return Series, the  Bond Series, the  Strategic Fixed Income  Series, the  World
Governments Series, the Growth With Income Series and the High Income Series may
write  (sell) covered put and call options  and purchase put and call options on
securities. Each  of these  Series  will write  options  on securities  for  the
purpose  of increasing its return and/or to  protect the value of its portfolio.
In particular, where a  Series writes an option  that expires unexercised or  is
closed  out by the Series at  a profit, it will retain  the premium paid for the
option which will increase its gross income and will offset in part the  reduced
value  of the portfolio security underlying the option, or the increased cost of
portfolio securities to be acquired. In  contrast, however, if the price of  the
underlying  security moves adversely to the  Series' position, the option may be
exercised and the  Series will be  required to purchase  or sell the  underlying
security  at a disadvantageous price, which may  only be partially offset by the
amount of  the premium.  Series 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.

By writing a  call option  on a  security, a  Series limits  its opportunity  to
profit  from any increase in the market  value of the underlying security, since
the holder will usually exercise  the call option when  the market value of  the
underlying  security exceeds the exercise price of the call. However, the Series
retains the risk of depreciation in value of securities on which it has  written
call options.

Each  of these Series may  also purchase put or  call options in anticipation of
market fluctuations which may adversely affect the value of its portfolio or the
prices of securities that  a Series wants  to purchase at a  later date. In  the
event  that the expected  market fluctuations occur,  the Series may  be able to
offset the  resulting adverse  effect on  its portfolio,  in whole  or in  part,
through  the options purchased. The  premium paid for a  put or call option plus
any transaction costs will  reduce the benefit, if  any, realized by the  Series
upon  exercise  or liquidation  of  the option,  and,  unless the  price  of the
underlying security changes sufficiently, the option may expire without value to
the Series.

                                       23
<PAGE>
In certain instances, the Strategic Fixed Income Series and the Emerging  Growth
Series may enter into options on Treasury securities that are "reset" options or
"adjustable  strike" options. These  options provide for  periodic adjustment of
the strike price and may also provide for the periodic adjustment of the premium
during the term of the option. The Statement of Additional Information  contains
a further discussion of these investments.

OPTIONS ON STOCK INDICES: Each of the Emerging Growth Series, the Growth Series,
the  Total Return Series, the Growth With Income Series and the Utilities Series
may write (sell) covered call and put options and purchase call and put  options
on  stock indices. Each of  these Series may write  options on stock indices for
the purpose of increasing its gross income and to protect its portfolio  against
declines  in  the value  of  securities it  owns or  increases  in the  value of
securities to be acquired. When a Series 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 Series will either close out the option at a profit or
allow  it to expire unexercised. A Series  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  a
Series  for  the  writing of  the  option,  less related  transaction  costs. In
addition, if  the value  of an  underlying index  moves adversely  to a  Series'
option  position, the option may be exercised,  and the Series will experience a
loss which may only be partially offset by the amount of the premium received.

Each of these Series 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
Series' possible loss in either case will be limited to the premium paid for the
option, plus related transaction costs.

"YIELD  CURVE" OPTIONS: Each of the Growth  Series, the Total Return Series, the
Bond Series, the Strategic Fixed Income Series, the World Governments Series and
the High Income Series may  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  (an effort  to  increase  current
income) 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,  and is  settled through  cash
payments.  Accordingly, a yield curve option is profitable to the holder if this
differential widens (in the case of a call)  or narrows (in the case of a  put),
regardless  of  whether  the yields  of  the underlying  securities  increase or
decrease. Yield curve options written by  a Series will be covered as  described
in  the Statement of Additional Information.  The trading of yield curve options
is subject to all the risks associated  with trading other types of options,  as
discussed  below  under  "Additional  Risk  Factors"  and  in  the  Statement of
Additional Information. In addition, such options present risks of loss even  if
the  yield on one of  the underlying securities remains  constant, if the spread
moves in a direction or to an extent which was not anticipated.

FUTURES CONTRACTS AND  OPTIONS ON FUTURES  CONTRACTS: Each of  the Total  Return
Series,   the  Bond  Series,  the  Strategic  Fixed  Income  Series,  the  World
Governments Series, the Limited Maturity Series, the High Income Series and  the
Utilities  Series may purchase and sell Futures Contracts on foreign or domestic
fixed income securities or indices of such securities, including municipal  bond
indices  and any  other indices of  foreign or domestic  fixed income securities
that may become available  for trading. Each of  these Series may also  purchase
and  write options on  such Futures Contracts  ("Options on Futures Contracts").
Each of the Emerging Growth Series,  the Growth Series, the Total Return  Series
and  the Growth With  Income Series may  purchase and sell  Futures Contracts on
stock indices, while the  Emerging Growth Series, the  Growth Series, the  Total
Return  Series, the Strategic Fixed Income Series, the World Governments Series,
the Growth With  Income Series and  the Utilities Series  may purchase and  sell
Futures  Contracts on foreign currencies or  indices of foreign currencies. Each
of these Series may also purchase and write Options on such Futures Contracts.

Such transactions will be entered into  for hedging purposes or for  non-hedging
purposes  to  the extent  permitted by  applicable law.  Each Series  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  the  Adviser  believes   that  use  of  such  contracts   will

                                       24
<PAGE>
benefit  a Series,  if its  investment judgment  about the  general direction of
exchange rates or the stock market is incorrect, the Series' overall performance
may be poorer than if it had not  entered into any such contract and the  Series
may  realize  a loss.  A  Series will  not enter  into  any Futures  Contract if
immediately thereafter the value of all open positions in Futures Contracts held
by such Series would exceed 50% of the value of its total assets.

Purchases of Options  on Futures Contracts  may present less  risk in hedging  a
Series'  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 Series may suffer a loss on the transaction.

Futures  Contracts and Options on  Futures Contracts that are  entered into by a
Series will be traded on U.S. and foreign exchanges.

FORWARD CONTRACTS: Each of  the Emerging Growth Series,  the Growth Series,  the
Research  Series, the Total Return Series,  the Bond Series, the Strategic Fixed
Income Series, the World Governments Series, the Growth With Income Series,  the
High  Income  Series and  the Utilities  Series 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 ("Forward Contracts").  Each of these Series
may enter into Forward Contracts for  hedging purposes and (except for the  Bond
Series  and the High Income Series)  for non-hedging purposes (I.E., speculative
purposes). By  entering  into  transactions in  Forward  Contracts  for  hedging
purposes,  a  Series 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, a Series  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, Forward  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 Series may choose to, or be required to, receive delivery of the
foreign  currencies  underlying Forward  Contracts  it has  entered  into. Under
certain circumstances, such as  where the Adviser  believes that the  applicable
exchange  rate is  unfavorable at  the time the  currencies are  received or the
Adviser anticipates, for any other reason, that the exchange rate will  improve,
the Fund may hold such currencies for an indefinite period of time. A Series may
also enter into a Forward Contract on one currency 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,  a reasonable  degree  of
correlation  can  be  expected  between  movements  in  the  values  of  the two
currencies. Each  of these  Series has  established procedures  consistent  with
statements  of the Securities and Exchange  Commission (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.

OPTIONS ON FOREIGN CURRENCIES:  Each of the Emerging  Growth Series, the  Growth
Series,  the Total  Return Series, the  Bond Series, the  Strategic Fixed Income
Series, the World Governments  Series, the Growth With  Income Series, the  High
Income  Series and the Utilities  Series 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 portfolio  securities and
against increases in the  dollar cost of  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 Series 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 Series' position, it may forfeit the entire amount of the premium paid  for
the  option plus related transaction  costs. A Series may  also choose to, or be
required to, receive delivery  of the foreign  currencies underlying Options  on
Foreign

                                       25
<PAGE>
Currencies  it has entered into. Under  certain circumstances, such as where the
Adviser believes that the  applicable exchange rate is  unfavorable at the  time
the  currencies are received  or the Adviser anticipates,  for any other reason,
that the exchange rate will  improve, a Series may  hold such currencies for  an
indefinite period of time.

6.  ADDITIONAL RISK FACTORS

OPTIONS,  FUTURES CONTRACTS AND FORWARD  CONTRACTS: Although certain Series will
enter into  transactions  in  options, Futures  Contracts,  Options  on  Futures
Contracts,  Forward  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 Series' hedging strategy unsuccessful and could result in losses.
Certain  Series also may enter into  transactions in options, Futures Contracts,
Options on  Futures  Contracts and  Forward  Contracts for  other  than  hedging
purposes,  which  involves greater  risk. In  particular, such  transactions may
result in losses for a Series which  are not offset by gains on other  portfolio
positions,  thereby reducing gross income. In addition, foreign currency markets
may be extremely volatile from time to time. There also can be no assurance that
a liquid secondary market will exist for  any contract purchased or sold, and  a
Series  may be  required to  maintain a  position until  exercise or expiration,
which could result in losses. The Statement of Additional Information contains a
description of the nature and  trading mechanics of options, 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 and  indexes
underlying options, Futures Contracts and Options on Futures Contracts traded by
the Series will include both domestic and foreign securities.

LOWER  RATED BONDS: Each of the Emerging Growth Series, the Research Series, the
Total Return Series, the Bond Series, the Limited Maturity Series, the Strategic
Fixed Income Series, the High Income Series and the Utilities Series may  invest
in  fixed income securities and, in the case of the Growth Series and the Growth
with Income Series, convertible securities rated Baa by Moody's or BBB by S&P or
Fitch and  comparable  unrated  securities.  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 securities.

Each  of these Series  (except the Limited  Maturity Series) may  also invest in
securities rated Ba  or lower  by Moody's or  BB or  lower by S&P  or Fitch  and
comparable  unrated securities  (commonly known as  "junk bonds")  to the extent
described  above.  These  securities  are  considered  speculative  and,   while
generally  providing greater income 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. However, since  yields
vary  over time, no  specific level of  income can ever  be assured. These lower
rated high yielding fixed income  securities generally tend to reflect  economic
changes  and short-term corporate and industry  developments to a greater extent
than higher  rated  securities which  react  primarily to  fluctuations  in  the
general  level  of  interest  rates (although  these  lower  rated  fixed income
securities are  also  affected  by  changes  in  interest  rates,  the  market's
perception of their credit quality, and the outlook for economic growth). In the
past,  economic downturns or  an increase in interest  rates have, under certain
circumstances, caused a  higher 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 Series'  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 Series 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
Series' yield despite the actual loss  of principal. The market for these  lower
rated   fixed  income  securities  may  be  less  liquid  than  the  market  for

                                       26
<PAGE>
investment grade  fixed income  securities, and  judgment may  at times  play  a
greater  role in valuing these  securities than in the  case of investment grade
fixed income securities. Changes in the value of securities subsequent to  their
acquisition  will not affect  cash income or  yield to maturity  to a Series but
will be  reflected in  the net  asset value  of shares  of the  Series. See  the
Statement  of  Additional  Information  for  more  information  on  lower  rated
securities.

FOREIGN SECURITIES: The Limited Maturity Series may invest in dollar-denominated
foreign debt securities.  The Money Market  Series may invest  in securities  of
foreign  issuers and  in securities  of foreign branches  of U.S.  banks such as
negotiable certificates  of  deposit  (Eurodollars). The  remaining  Series  may
invest  in  dollar-denominated  and  non-dollar/denominated  foreign securities.
Investing  in  securities  of  foreign  issuers  generally  involves  risks  not
ordinarily  associated with investing  in securities of  domestic issuers. These
include changes in  currency rates, exchange  control regulations,  governmental
administration  or economic or monetary policy  (in the United States or abroad)
or  circumstances  in  dealings  between  nations.  Costs  may  be  incurred  in
connection  with conversions between  various currencies. Special considerations
may  also  include  more  limited  information  about  foreign  issuers,  higher
brokerage  costs, different  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  United States.  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.  All of  the
Series  except the Limited Maturity Series and  the Money Market Series may hold
foreign currency received in connection  with investments in foreign  securities
when,  in the judgment  of the 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  rate.  Such  Series  may  also  hold  foreign  currency  in
anticipation of purchasing foreign securities.  See the Statement of  Additional
Information  for further  discussion of  foreign securities  and the  holding of
foreign currency, as well as the associated risks.

AMERICAN DEPOSITARY RECEIPTS:  Each of  the Series except  the Limited  Maturity
Series  and the Money  Market Series may  invest in 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. Because  ADRs  trade  on United  States  securities  exchanges,  the
Adviser  does not treat them as foreign securities. However, they are subject to
many of the risks of  foreign securities such as  changes in exchange rates  and
more limited information about foreign issuers.

Each  of  the Growth  Series, Growth  With Income  Series, Total  Return Series,
Utilities Series, World Governments Series, Strategic Fixed Income Series,  Bond
Series  and Limited Maturity Series may  invest in emerging markets. In addition
to the general risks of investing in foreign securities, investments in emerging
markets involve special risks.  Securities of many  issuers in emerging  markets
may  be less  liquid and  more volatile  than securities  of comparable domestic
issuers. These securities  may be  considered speculative  and, while  generally
offering  higher income and the potential  for capital appreciation, may present
significantly greater risk.  Emerging markets may  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 the
Series is  uninvested and  no return  is earned  thereon. The  inability of  the
Series  to make  intended security  purchases due  to settlement  problems could
cause the  Series  to miss  attractive  investment opportunities.  Inability  to
dispose  of portfolio securities due to  settlement problems could result either
in losses to the  Series due to  subsequent declines in  value of the  portfolio
securities  or, if the Series has entered  into a contract to sell the security,
possible liability to  the purchaser.  Certain markets may  require payment  for
securities  before  delivery.  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 of  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

                                       27
<PAGE>
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 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.  The Series  could  be adversely
affected by delays in, or a refusal to grant, any required governmental approval
for repatriation of capital, as well as by the application to the Series 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 the Series.

RESTRICTED  SECURITIES: Each  of the  Series (except  the Growth  Series and the
Growth With Income Series) may purchase securities that are not registered under
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"). The Trust's Board of Trustees determines, based upon a
continuing review of  the trading  markets for  a specific  Rule 144A  security,
whether  such security is illiquid and thus subject to the Series' limitation on
investing not more  than 15% of  its net assets  (not more than  10% of its  net
assets  in the  case of  the Money  Market Series)  in illiquid  investments, or
liquid and  thus not  subject to  such  limitation. The  Board of  Trustees  has
adopted  guidelines and delegated  to MFS the daily  function of determining and
monitoring the  liquidity of  Rule  144A securities.  The Board,  however,  will
retain   sufficient   oversight   and   be   ultimately   responsible   for  the
determinations. The Board  will carefully  monitor each  Series' investments  in
Rule  144A  securities, focusing  on such  important  factors, among  others, as
valuation, liquidity and availability  of information. This investment  practice
could  have the effect of increasing the level of illiquidity in a Series to the
extent that qualified  institutional buyers  become for a  time uninterested  in
purchasing Rule 144A securities held in the Fund's portfolio.

NON-DIVERSIFICATION:  Each of the World  Governments Series, the Strategic Fixed
Income Series and  the Utilities Series  is "non-diversified," as  that term  is
defined  in the Investment Company Act of 1940 ( the "1940 Act"), but intends to
qualify as  a "regulated  investment  company" ("RIC")  for federal  income  tax
purposes.  This means,  in general,  that although more  than 5%  of the Series'
total assets  may be  invested in  the  securities of  one issuer  (including  a
foreign  government),  at the  close of  each  quarter of  its taxable  year the
aggregate amount of such holdings may not  exceed 50% of the value of its  total
assets, and no more than 25% of the value of its total assets may be invested in
the  securities of a single issuer. To  the extent that a non-diversified Series
at times may hold the securities of a smaller number of issuers than if it  were
"diversified"  (as defined in  the 1940 Act),  the Series will  at such times be
subject to greater  risk with respect  to its portfolio  securities than a  fund
that  invests in a broader range of securities, because changes in the financial
condition or market assessment of a single issuer may cause greater fluctuations
in the Series' total return and the net asset value of its shares.
                              -------------------

SHORT-TERM INVESTMENTS  FOR  DEFENSIVE PURPOSES  --  During periods  of  unusual
market  conditions  when  the  Adviser  believes  that  investing  for defensive
purposes is appropriate, or in order to meet anticipated redemption requests,  a
large  portion or  all of  the assets  of each  Series may  be invested  in cash
(including foreign currency) or cash equivalents including, but not limited  to,
obligations  of banks (including certificates  of deposit, bankers' acceptances,
time deposits and  repurchase agreements), commercial  paper, short-term  notes,
U.S.  Government Securities and related repurchase agreements. See Appendix A to
this Prospectus for  a description  of U.S. Government  obligations and  certain
short-term investments.

PORTFOLIO TRADING

Each Series intends to manage its portfolio by buying and selling securities, as
well as holding securities to maturity, to help attain its investment objectives
and policies.

                                       28
<PAGE>
Each  Series will engage in portfolio trading  if it believes a transaction, net
of costs (including custodian  charges), will help  in attaining its  investment
objectives. In trading portfolio securities, a Series seeks to take advantage of
market developments, yield disparities and variations in the creditworthiness of
issuers.  For a description of the strategies which may be used by the Series in
trading  portfolio  securities,  see   "Portfolio  Transactions  and   Brokerage
Commissions"  in the  Statement of  Additional Information.  Because each Series
(except the Money Market Series) is  expected to have a portfolio turnover  rate
of  over 100%, transaction costs  incurred by each such  Series and the realized
capital gains and losses of each such Series may be greater than that of a  fund
with a lesser portfolio turnover rate.

The  primary  consideration  in  placing  portfolio  security  transactions with
broker-dealers for execution  is to  obtain, and maintain  the availability  of,
execution  at  the  most  favorable  prices and  in  the  most  effective manner
possible. Consistent with the foregoing primary consideration, the Rules of Fair
Practice of the National  Association of Securities  Dealers, Inc. (the  "NASD")
and  such other policies as the Trustees of the Trust may determine, the Adviser
may consider sales of VLI  policies and VA contracts for  which the Trust is  an
investment  option, together  with sales of  shares of  other investment company
clients of MFS Fund Distributors, Inc.,  the distributor of shares of the  Trust
and  of the MFS Family of Funds, as  a factor in the selection of broker-dealers
to execute each Series'  portfolio transactions. From time  to time the  Adviser
may direct certain portfolio transactions to broker-dealer firms which, in turn,
have  agreed  to pay  a portion  of  the Series  operating expenses  (e.g., fees
charged by the  custodian of the  Series' assets). For  a further discussion  of
portfolio trading, see the Statement of Additional Information.
                              -------------------

The   Statement  of  Additional  Information  includes  a  discussion  of  other
investment policies and listing of specific investment restrictions which govern
the investment policies  of each  Series. The  specific investment  restrictions
listed  in the  Statement of Additional  Information may not  be changed without
shareholder approval (see the Statement of Additional Information). The  Series'
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 SERIES

The Trust's Board of Trustees, as part of its overall management responsibility,
oversees  various  organizations   responsible  for   each  Series'   day-to-day
management.

INVESTMENT ADVISER -- MFS manages each Series pursuant to an Investment Advisory
Agreement  with the  Trust on behalf  of each  Series dated April  14, 1994 (the
"Advisory Agreement"). MFS provides the Series with overall investment  advisory
and  administrative services, as  well as general  office facilities. Subject to
such policies as the Trustees may determine, MFS makes investment decisions  for
each  Series. For  its services and  facilities, MFS receives  a management fee,
computed and paid monthly, in an amount  equal to the following annual rates  of
the average daily net assets of each Series:

For  the  World Governments  Series' fiscal  year ended  December 31,  1994, MFS
received management  fees  under  the  Series'  Advisory  Agreement  of  $7,604.
Pursuant to the reimbursement plan discussed on page four of this prospectus for
its  fiscal year-ended  December 31,  1994 MFS  reimbursed the  World Government
Series $36,473.

Except where indicated otherwise, the  identity and background of the  portfolio
manager  for each Series is set forth below. Each portfolio manager has acted in
that capacity since the commencement of investment operations of each Series.

MFS   and  its  wholly-owned  subsidiary  MFS  Asset  Management  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 United States, Massachusetts  Investors
Trust.   Net  assets  under   the  management  of   the  MFS  organization  were
approximately $   billion on behalf of approximately   million investor accounts
as of                       .  As of  such date,  the MFS  organization  managed
approximately   $    billion  of  assets   invested  in  equity  securities  and
approximately $     billion  of  assets  invested in  fixed  income  securities.
Approximately $  billion of the assets managed by MFS are invested in securities
of  foreign issuers and non-U.S.  dollar-denominated securities of U.S. issuers.
MFS is  a  subsidiary  of  Sun  Life  of Canada  (U.S.),  which  in  turn  is  a

                                       30

subsidiary  of Sun Life Assurance Company  of Canada ("Sun Life"). The Directors
of MFS are A. Keith Brodkin, Jeffrey L. Shames, Arnold D. Scott, John D.  McNeil
and  John R. Gardner. 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 Gardner 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 United
States 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 and  a Director  of MFS,  is the  Chairman and
President and a Trustee of the Trust. W. Thomas London, Stephen E. Cavan,  James
R.  Bordewick, Jr.,  and James  O. Yost, all  of whom  are officers  of MFS, are
officers of the Trust.

From time to time, the Adviser may  purchase, redeem and exchange shares of  any
Series. The purchase by the Adviser of shares of a Series may have the effect of
lowering  that Series'  expense ratio,  while the  redemption by  the Adviser of
shares of a Series may have the effect of increasing that Series' expense ratio.

DISTRIBUTOR -- MFS Fund Distributors, Inc. ("MFD"), a wholly-owned subsidiary of
MFS, is the distributor of shares of each Series and also serves as  distributor
for certain of the other mutual funds managed by MFS.

SHAREHOLDER  SERVICING  AGENT  --  MFS Service  Center,  Inc.  (the "Shareholder
Servicing Agent"), a wholly owned  subsidiary of MFS, performs transfer  agency,
certain dividend disbursing agency and other services for each Series.

8.  INFORMATION CONCERNING SHARES OF EACH SERIES

PURCHASES AND REDEMPTIONS

The  separate accounts of the Participating  Insurance Companies place orders to
purchase and redeem  shares of  each Series based  on, among  other things,  the
amount of premium payments to be invested and surrender and transfer requests to
be  effected on that day pursuant to Contracts. Orders received by the Trust are
effected on days on which the Exchange is open for trading. For orders  received
by  the Trust before  the close of  regular trading on  the Exchange (normally 4
p.m. eastern time), such purchases and redemptions of the shares of each  Series
are  effected at the respective net asset  values per share determined as of the
close of  regular  trading on  the  Exchange  on that  same  day.  Participating
Insurance  Companies shall be the designee of  the Trust for receipt of purchase
and redemption orders from Contract holders  and receipt by such designee  shall
constitute receipt by the Trust; provided that the Trust receives notice of such
order  by 9:30 a.m. eastern time on the next following day on which the Exchange
is open for trading. Payment for shares shall be by federal funds transmitted by
wire and must be received by 2:00 p.m. eastern time on the next following day on
which the Exchange  is open for  trading after the  purchase order is  received.
Redemption  proceeds shall be by federal funds  transmitted by wire and shall be
sent by 2:00 p.m. eastern time on  the next following day on which the  Exchange
is  open for trading after  the redemption order is  received. No fee is charged
the shareholders when they redeem Series shares.

The offering of shares of any Series may  be suspended for a period of time  and
each  Series reserves the right to  refuse any specific purchase order. Purchase
orders may be  refused if, in  the Adviser's opinion,  they are of  a size  that
would  disrupt the management  of a Series.  The Trust may  suspend the right of
redemption of shares of any Series and may postpone payment for any period:  (i)
during  which the  Exchange is closed  other than customary  weekend and holiday
closings or during which  trading on the Exchange  is restricted; (ii) when  the
SEC  determines  that a  state of  emergency  exists which  may make  payment or
transfer not reasonably practicable;  (iii) as the SEC  may by order permit  for
the  protection of the security  holders of the Trust; or  (iv) at any time when
the Trust may, under applicable laws, rules and regulations, suspend payment  on
the redemption of its shares.

Should  any conflict between  Contract holders arise which  would require that a
substantial amount of net assets be withdrawn from any Series, orderly portfolio
management could be disrupted to the potential detriment of such Contract.

                                       31
<PAGE>
NET ASSET VALUE

The net asset value per share of each Series is determined each day during which
the  Exchange is open for  trading. This determination is  made once during each
such day as of  the close of  regular trading on the  Exchange by deducting  the
amount  of the  Series' liabilities  from the  value of  the Series'  assets and
dividing the  difference by  the number  of shares  of the  Series  outstanding.
Values  of assets in  a Series' portfolio  are determined on  the basis of their
market or other fair value (amortized cost value in the case of the Money Market
Series),  as  described  in  the   Statement  of  Additional  Information.   All
investments,  assets and  liabilities are expressed  in U.S.  dollars based upon
current currency exchange rates.

DISTRIBUTIONS
Substantially all  of  each  Series'  (except  the  Money  Market  Series')  net
investment income for any calendar year is declared as dividends and paid to its
shareholders  as dividends on an annual basis. In addition, each Series 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 to its
shareholders from short-term  capital gains. In  determining the net  investment
income  available  for distribution,  a Series  may rely  on projections  of its
anticipated net investment  income (which may  include short-term capital  gains
from  the sales  of securities  or other  assets, and,  if allowed  by a Series'
investment restrictions, premiums  from options  written), over  a longer  term,
rather than its actual net investment income for the period.

Substantially  all of  the Money  Market Series'  net investment  income for any
calendar year is  declared as dividends  daily and paid  to its shareholders  as
dividends  on a monthly basis. Generally, those dividends are distributed on the
last business day of  the month in  the form of additional  shares of the  Money
Market  Series at the rate  of one share (and  fraction thereof) for each dollar
(and  fraction  thereof)  of  dividend  income  or,  at  the  election  of   the
shareholder,  in cash. Shares purchased become entitled to dividends declared as
of the first day following the date of investment.

Shareholders of any  of the Series  may elect to  receive dividends and  capital
gain distributions in either cash or additional shares.

TAX STATUS

Each  Series of the Trust is treated as a separate entity for federal income tax
purposes. In order to minimize the taxes each Series would otherwise be required
to pay, each  Series intends  to qualify each  year as  a "regulated  investment
company"  under Subchapter M  of the Internal  Revenue Code of  1986, as amended
("the Code"), and to make distributions  to its shareholders in accordance  with
the  timing requirements imposed by the Code. It is not expected that any of the
Series will be required to pay entity level federal income or excise taxes.

Shares of the Series are offered only to the Participating Insurance  Companies'
separate  accounts that fund  Contracts. See the  applicable Contract prospectus
for a  discussion  of the  federal  income tax  treatment  of (1)  the  separate
accounts  that  purchase and  hold  Series shares  and  (2) the  holders  of the
Contracts  that  are  funded  through   those  accounts.  In  addition  to   the
diversification  requirements  of Subchapter  M of  the  Code, each  Series also
intends to diversify its assets as  required by Code Section 817(h)(1), and  the
regulations  thereunder. See  also "Tax Status"  in the  Statement of Additional
Information."

DESCRIPTION OF SHARES, VOTING RIGHTS AND LIABILITIES

Each Series currently  has one class  of shares, entitled  Shares of  Beneficial
Interest  (without par value).  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 with respect  to that Series, but  shares of all  Series
vote  together  in  the  election  of  Trustees  and  selection  of accountants.
Additionally, each Series will vote separately on any other matter that  affects
solely  that Series, but will  otherwise vote together with  all other Series on
all other  matters.  The  Trust  does not  intend  to  hold  annual  shareholder
meetings.  The 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 Statement of Additional Information.

                                       32
<PAGE>
Each  share of a Series represents an equal proportionate interest in the Series
with each share,  subject to the  liabilities of the  particular Series.  Shares
have   no  pre-emptive  or   conversion  rights.  Shares   are  fully  paid  and
non-assessable. Should  a Series  be liquidated,  shareholders are  entitled  to
share  PRO RATA  in the net  assets available for  distribution to shareholders.
Shares  will  remain  on  deposit  with  the  Shareholder  Servicing  Agent  and
certificates will not be issued.

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  is  limited to  circumstances  in which  both  inadequate
insurance  existed (E.G., fidelity bonding and omission insurance) and the Trust
itself was unable to meet its obligations.

As of December 31, 1994, Century Life  of America on behalf of Century  Variable
Annuity Account, 2000 Heritage Way, Waverly, Florida 50677-9208 was the owner of
69.22% of the outstanding shares of the World Governments Series. As of December
31,  1994, Massachusetts Financial  Services Company Inc.,  500 Bolyston Street,
Boston, Massachusetts  02116-3740 was  the approximate  owner of  29.99% of  the
outstanding shares of the World Governments Series.

PERFORMANCE INFORMATION

Each  Series' performance may  be quoted in  advertising in terms  of yield and,
except for  the Money  Market  Series, total  return.  Performance is  based  on
historical   results  and  is  not  intended  to  indicate  future  performance.
Performance quoted for a  Series includes the effect  of deducting that  Series'
expenses,  but  may  not  include  charges  and  expenses  attributable  to  any
particular insurance  product.  Excluding these  charges  from quotations  of  a
Series'  performance  has  the  effect  of  increasing  the  performance quoted.
Performance for a  Series will  vary based on,  among other  things, changes  in
market  conditions, the  level of  interest rates and  the level  of the Series'
expenses. For further information about the World Governments Series performance
for the  fiscal year  ended December  31, 1994,  please see  the Series'  annual
report. A copy of the annual report may be obtained without charge by contacting
the Shareholder Servicing Agent (see back cover for address and phone number.)

MONEY  MARKET SERIES: From time to time,  quotations of the Money Market Series'
"yield"  and  "effective  yield"  may  be  included  in  advertisements,   sales
literature or reports to shareholders or prospective investors. The yield of the
Money  Market Series refers to the net investment income generated by the Series
over a specified  seven-day period (the  ending date of  which will be  stated).
Included  in "net  investment income" is  the amortization of  market premium or
accretion  of  market  and  original   issue  discount.  This  income  is   then
"annualized."  That is, the amount of income generated by the Series during that
week is assumed to be  generated during each week over  a 365 day period and  is
shown  as a  percentage. The  effective yield  is expressed  similarly but, when
annualized, the income earned by  an investment in the  Series is assumed to  be
reinvested.  The effective yield will be  slightly higher than the yield because
of the compounding effect of this assumed reinvestment.

OTHER SERIES: From time to time, quotations of a Series' total return and  yield
may  be included in advertisements, sales  literature or reports to shareholders
or prospective investors. The total return of a Series refers to return assuming
an investment has been held in the Series  for one year and for the life of  the
Series  (the ending date of  which will be stated).  The total return quotations
may be expressed in terms  of average annual or  cumulative rates of return  for
all  periods quoted.  Average annual total  return refers to  the average annual
compound rate of return  of an investment in  a Series. Cumulative total  return
represents  the cumulative change  in value of  an investment in  a Series. Both
will assume that all dividends and capital gains distributions were  reinvested.
The yield of a Series refers to net investment income generated by a Series over
a specified 30-day (or one month) period. This income is then "annualized." That
is,  the amount  of income generated  by the  Series during that  30-day (or one
month) period is assumed to be generated over a 12-month period and is shown  as
a percentage of net asset value.

EXPENSES

The  Trust pays the compensation of the Trustees who are not officers of MFS and
all expenses of each Series (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 each  Series; fees  and expenses  of
independent  auditors, of legal counsel, and of any transfer agent, registrar or
dividend disbursing agent of each Series; expenses of repurchasing and redeeming
shares and

                                       33
<PAGE>
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  Investors Bank &  Trust Company, the
Trust's Custodian, for  all services  to each Series,  including safekeeping  of
funds  and securities and  maintaining required books  and accounts; expenses of
calculating the  net asset  value of  shares  of each  Series; and  expenses  of
shareholder  meetings.  Expenses  relating  to  the  issuance,  registration and
qualification of shares of each Series and the preparation, printing and mailing
of prospectuses are borne by each Series 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
are allocated between the Series in a manner believed by management of the Trust
to be fair and equitable.

Subject  to termination or revision at the  discretion of MFS, MFS has agreed to
pay until December  31, 2004  the foregoing  expenses of  the World  Governments
Series (except for fees paid under the Advisory Agreement) such that the Series'
aggregate operating expenses do not exceed, on an annualized basis, 1.00% of its
average  daily net assets. Such payments by  MFS are subject to reimbursement by
the World Governments Series  which will be accomplished  by the payment by  the
Series  of an expense  reimbursement fee 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 the aggregate operating
expenses of the Series would  not exceed, on an  annualized basis, 1.00% of  its
average daily net assets. The expense reimbursement agreement terminates for the
World  Governments Series  on the  earlier of  the date  on which  payments made
thereunder by the Series equal the  prior payment of such reimbursable  expenses
by MFS or December 31, 2004.

Subject  to termination or revision at the  discretion of MFS, MFS has agreed to
pay expenses of each of the Series (except the World Governments Series and  the
Money  Market  Series)  such  that the  respective  Series'  aggregate operating
expenses shall not exceed,  on an annualized basis,  1.00% of the average  daily
net  assets of the respective Series from  November 2, 1994 through December 31,
1996, 1.25%  of the  average daily  net  assets of  the respective  Series  from
January  1, 1997 through December  31, 1998, and 1.50%  of the average daily net
assets of the respective Series thereafter. Such payments by MFS are subject  to
reimbursement  by each Series which  will be accomplished by  the payment of the
Series of an expense  reimbursement fee to  MFS computed and  paid monthly at  a
percentage  of  the respective  Series' average  daily net  assets for  its then
current fiscal year, with a limitation  that immediately after such payment  the
aggregate  operating expenses of  the respective Series would  not exceed, on an
annualized basis, 1.00% of the average daily net assets of the respective Series
through December  31,  1996,  1.25% of  the  average  daily net  assets  of  the
respective  Series from January 1, 1997 through  December 31, 1998, and 1.50% of
the average daily net assets of  the respective Series thereafter. This  expense
reimbursement  agreement terminates for  each such Series on  the earlier of the
date on which payments made thereafter by the respective Series equal the  prior
payment of such reimbursable expenses by MFS or December 31, 2004.

Subject  to termination or revision at the  discretion of MFS, MFS has agreed to
pay until December 31, 2004, expenses of the Money Market Series (the  "Series")
such  that  the Series'  aggregate operating  expenses shall  not exceed,  on an
annualized basis, 0.60% of the average daily net assets of the Series; provided,
however, that this obligation may  be terminated or revised  at any time by  MFS
without  the consent of the Trust or the Series by notice in writing from MFS to
the Trust  on  behalf  of the  Series.  Such  payments by  MFS  are  subject  to
reimbursement  by the Series, which  will be accomplished by  the payment by the
Series of an expense  reimbursement fee to  MFS computed and  paid monthly at  a
percentage  of the average daily  net assets of the  Series for its then current
fiscal year, with a limitation that immediately after such payment the aggregate
operating expenses of the Series would not exceed, on an annualized basis, 0.60%
of its average daily net assets.  This expense reimbursement terminates for  the
Series  on the  earlier of the  date on  which payments made  thereunder by such
Series equal the prior payments of such reimbursable expenses by MFS or December
31, 2004.

               DESCRIPTION OF OBLIGATIONS ISSUED OR GUARANTEED BY
           U.S. GOVERNMENT AGENCIES, AUTHORITIES OR INSTRUMENTALITIES

U.S.  GOVERNMENT  OBLIGATIONS --  are issued  by the  U.S. Treasury  and include
bills,  certificates   of   indebtedness,   notes  and   bonds.   Agencies   and
instrumentalities  of the U.S. Government are established under the authority of
an act of Congress  and include, but  are not limited  to, the Tennessee  Valley

Home Loan Banks, Federal  Intermediate Credit Banks and  Federal Land Banks,  as
well as those listed below.

Government.

GNMA  CERTIFICATES  --  are  mortgage-backed  securities,  with  timely  payment
guaranteed  by the full faith and credit of the U.S. Government, which represent
a partial ownership interest in a pool of mortgage loans issued by lenders  such
as  mortgage bankers, commercial  banks and savings  and loan associations. Each
mortgage loan included in the pool is also insured or guaranteed by the  Federal
Housing   Administration,  the  Veterans  Administration  or  the  Farmers  Home

the  U.S. Treasury; still  others, such as  bonds issued by  SLMA, are supported
only by the credit of  the instrumentality. No assurance  can be given that  the
U.S. Government will provide financial support to instrumentalities sponsored by
the  U.S. Government as it is not obligated  by law, in certain instances, to do
so.

                          DESCRIPTION OF BOND RATINGS

The ratings of Moody's, S&P and Fitch represent their opinions as to the quality
of various debt instruments. It should be emphasized, however, that ratings  are
not  absolute standards of quality. Consequently, debt instruments with the same
maturity, coupon and rating may have different yields while debt instruments  of
the same maturity and coupon with different ratings may have the same yield.

                        MOODY'S INVESTORS SERVICE, INC.

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 fluctuations of protective  elements
may  be of greater amplitude  or there may be  other elements present which make
the long-term risks 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 sometime 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. Such  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;

                                      B-1
<PAGE>
    3.  there is a lack of essential data pertaining to the issue or issuer; and

    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.

                        STANDARD & POOR'S RATINGS GROUP

AAA:  Debt rated AAA has  the highest rating assigned  by S&P's. 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  circumstances  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.

C1:  The rating C1  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
rating 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.

                                      B-2
<PAGE>
A-1 AND P-1 COMMERCIAL PAPER RATINGS

Description of S&P and Moody's highest commercial paper ratings:

The  rating "A"  is the  highest commercial  paper rating  assigned by  S&P, and
issues so rated are regarded as having the greatest capacity for timely payment.
Issues in  the "A"  category are  delineated  with the  numbers 1,  2 and  3  to
indicate  the relative degree of safety.  The A-1 designation indicates that the
degree of safety regarding timely payment is either overwhelming or very strong.
Those A-1 issues determined to possess overwhelming safety characteristics  will
be denoted with a plus (+) sign designation.

The  rating  P-1 is  the highest  commercial paper  rating assigned  by Moody's.
Issuers rated P-1 have a superior ability for repayment. P-1 repayment  capacity
will  normally be evidenced by the following characteristics: (1) leading market
positions in well  established industries;  (2) high  rates of  return on  funds
employed;  (3) conservative  capitalization structure with  moderate reliance on
debt and ample asset protection; (4) broad margins in earnings coverage of fixed
financial charges and high  internal cash generation;  and (5) well  established
access  to  a  range  of  financial markets  and  assured  sources  of alternate
liquidity.

                         FITCH INVESTORS SERVICE, INC.

AAA: Bonds considered to be investment grade and of the highest credit  quality.
The  obligor  has an  exceptionally strong  ability to  pay interest  and prepay
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 of principal.

PLUS(+) MINUS(-): Plus and minus signs are used with a rating symbol to indicate
the  relative position  of a  credit within the  rated category.  Plus and minus
signs, however, are not used in the 'AAA' category.

NR indicates that Fitch does not rate the specific issue.

                                      B-3
<PAGE>
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  a  "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.

                  PRINCIPAL SECTORS OF THE UTILITIES INDUSTRY

The principal sectors of the utility industry in which the Utilities Series  may
invest are discussed below.

ELECTRIC -- The electric utility industry consists of companies that are engaged
principally  in  the  generation,  transmission  and  sale  of  electric energy,
although many  also provide  other  energy-related services.  Domestic  electric
utility  companies, in general,  recently have been  favorably affected by lower
fuel and financing costs and the  full or near completion of major  construction
programs.  In addition,  many of  these companies  recently have  generated cash
flows in excess  of current  operating expenses  and construction  expenditures,
permitting  some  degree of  diversification  into unregulated  businesses. Some
electric utilities have also taken advantage of the right to sell power  outside
of  their traditional geographic areas.  Electric utility companies historically
have been  subject to  the risks  associated with  increases in  fuel and  other
operating   costs,  high  interest  costs   on  borrowings  needed  for  capital
construction programs, costs associated  with compliance with environmental  and
safety regulations and changes in the regulatory climate.

In  the  U.S., the  construction and  operation of  nuclear power  facilities is
subject to  increased scrutiny  by,  and evolving  regulations of,  the  Nuclear
Regulatory   Commission  and  state  agencies  having  comparable  jurisdiction.
Increased scrutiny might  result in  higher operating costs  and higher  capital
expenditures,  with the risk that the regulators may disallow inclusion of these
costs in rate authorizations or the risk that a company may not be permitted  to
operate  or  complete  construction of  a  facility. In  addition,  operators of
nuclear power plants may be subject to significant costs for disposal of nuclear
fuel and for the de-commissioning of such plants.

TELECOMMUNICATIONS -- The telephone industry  is large and highly  concentrated.
Companies that distribute telephone services and provide access to the telephone
networks  comprise the greatest portion of  this segment. Telephone companies in
the U.S. are still experiencing the effects of the breakup of American Telephone
& Telegraph Company, which  occurred in 1984. Since  1984, companies engaged  in
telephone  communication services  have expanded  their non-regulated activities
into other businesses, including  cellular telephone services, data  processing,
equipment  retailing,  computer software  and  hardware services,  and financial
services. This  expansion has  provided  significant opportunities  for  certain
telephone  companies to  increase their earnings  and dividends  at faster rates
than  had  been  allowed  in  traditionally  regulated  businesses.   Increasing
competition,  technological innovations  and other  structural changes, however,
could adversely affect the profitability of such utilities.

GAS --  Gas  transmission companies  and  gas distribution  companies  are  also
undergoing  significant changes. In the  U.S., interstate transmission companies
are regulated by the Federal Energy Regulatory Commission, which is reducing its
regulation of the  industry. Many companies  have diversified into  oil and  gas
exploration  and development, making returns more sensitive to energy prices. In
the recent  decade,  gas  utility  companies have  been  adversely  affected  by
disruptions  in  the  oil industry  and  have  also been  affected  by increased
concentration  and  competition.  In  the  opinion  of  the  Adviser,   however,
environmental  considerations  could improve  the  gas industry  outlook  in the
future. For example, natural gas is  the cleanest of the hydrocarbon fuels,  and
this may result in incremental shifts in fuel consumption toward natural gas and
away from oil and coal.

WATER  -- Water supply utilities are  companies that collect, purify, distribute
and sell  water. In  the  U.S. and  around the  world,  the industry  is  highly
fragmented  because  most  of  the  supplies  are  owned  by  local authorities.
Companies in this industry are generally  mature and are experiencing little  or
no per capita volume growth.

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

There  can be no assurance that the positive developments noted above, including
those relating to  changing regulation, will  occur or that  risk factors  other
than those noted above will not develop in the future.

management investment company  (a "mutual fund")  consisting of twelve  separate
series:  MFS Emerging Growth  Series (the "Emerging  Growth Series"), MFS Growth
Series (the "Growth Series"), MFS  Research Series (the "Research Series"),  MFS
Growth  With Income Series  (the "Growth With Income  Series"), MFS Total Return
Series (the  "Total  Return  Series"),  MFS  Utilities  Series  (the  "Utilities

"Prospectus").

Each Series' investment adviser and distributor is, respectively,  Massachusetts
Financial  Services Company ("MFS" or the  "Adviser") and MFS Fund Distributors,
Inc. ("MFD" or the "Distributor"), each a Delaware corporation.

2.  INVESTMENT TECHNIQUES

LENDING OF PORTFOLIO  SECURITIES: Each of  the Series (except  the Money  Market
Series)  may seek to  increase its income by  lending portfolio securities. Such
loans will usually be made only to  member firms of the New York Stock  Exchange
(the  "Exchange") (and  subsidiaries thereof)  and member  banks of  the Federal
Reserve System, and would be required  to be secured continuously by  collateral
in  cash,  cash  equivalents  or  United  States  ("U.S.")  Treasury  securities
maintained on a current basis at an amount at least equal to the market value of
the securities loaned. A Series would have  the right to call a loan and  obtain
the securities loaned at any time on customary industry settlement notice (which
will  not usually exceed  five business days).  For the duration  of a loan, the
Series would continue  to receive the  equivalent of the  interest or  dividends
paid  by the issuer on the securities loaned and would also receive compensation
from the investment of the collateral.  The Series would not, however, have  the
right  to vote any securities  having voting rights during  the existence of the
loan, but the Series 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 to be of
good standing, and when, in the judgment of the Adviser, the consideration which
can be  earned  currently from  securities  loans  of this  type  justifies  the
attendant  risk.  If the  Adviser  determines to  make  securities loans,  it is
intended that the value  of the securities  loaned would not  exceed 30% of  the
value of a Series' total assets.

REPURCHASE  AGREEMENTS: Each of the Series  may enter into repurchase agreements
with sellers who are member firms (or  a subsidiary thereof) of the Exchange  or
members  of  the  Federal  Reserve System,  recognized  primary  U.S. Government
securities dealers or  institutions which the  Adviser has determined  to be  of
comparable  creditworthiness. The securities  that a Series  purchases and holds
through its agent are U.S. Government securities, the values of 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 Series,  or the purchase  and repurchase prices  may be the same,
with interest at a standard rate due to the Series together with the  repurchase
price  on repurchase. In either  case, the income to  the Series is unrelated to
the interest rate on the Government securities.

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 Series will have the right to liquidate the securities. If at the time
the Series 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 Series' exercise of  its
right  to liquidate the securities  may be delayed and  result in certain losses
and costs to the  Series. Each Series has  adopted and follows procedures  which
are  intended to minimize the risks  of repurchase agreements. For example, each
Series only enters into repurchase  agreements after the Adviser has  determined
that  the  seller  is  creditworthy,  and  the  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 a Series has the right to make  margin
calls  at any time  if the value of  the securities falls  below the agreed upon
margin.

"WHEN-ISSUED" SECURITIES: Each of  the Series (except  the Research Series,  the
World Governments Series and the Money Market Series) may purchase securities on
a  "when-issued" or  on a  "forward delivery"  basis. Although  a Series  is not
limited as to the amount of these  securities for which it may have  commitments
to  purchase on such bases,  it is expected that  under normal circumstances the
Series will not commit more than 20% of its total assets to such purchases. When
a Series commits  to purchase these  securities on a  "when-issued" or  "forward
delivery" basis, it will set up procedures consistent with the General Statement
of  Policy of the Securities and Exchange Commission (the "SEC") concerning such
purchases. Since that policy currently recommends that an amount of the  Series'
assets  equal to the  amount of the purchase  be held aside  or segregated to be
used to pay  for the commitment,  the Series will  always have cash,  short-term
money market instruments or high quality debt securities sufficient to cover any
commitments  or to limit any potential risk.  Although no Series intends to make
such purchases for speculative purposes and each Series 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  Series  may have

                                       2
<PAGE>
to sell assets which have been set aside in order to meet redemptions. Also,  if
a  Series  determines it  is  necessary to  sell  the "when-issued"  or "forward
delivery" securities before  delivery, the Series  may incur a  loss because  of
market  fluctuations since the  time the commitment  to purchase such securities
was made.

MORTGAGE "DOLLAR ROLL" TRANSACTIONS: Each of  the Total Return Series, the  Bond
Series,  the Strategic  Fixed Income Series,  the World  Governments Series, the
Limited Maturity Series,  the High Income  Series and the  Utilities Series  may
enter  into  mortgage  "dollar roll"  transactions  pursuant to  which  it sells
mortgage-backed  securities  for  delivery  in  the  future  and  simultaneously
contracts  to repurchase substantially similar  securities on a specified future
date. During the roll period, a  Series foregoes principal and interest paid  on
the mortgage-backed securities. A Series is compensated for the lost interest by
the  difference between  the current  sales price  and the  lower price  for the
future purchase (often referred  to as the  "drop") as well  as by the  interest
earned  on  the  cash  proceeds  of  the initial  sale.  A  Series  may  also be
compensated by receipt of  a commitment fee.  In the event  that the party  with
whom  the  Series contracts  to replace  substantially  similar securities  on a
future date fails  to deliver such  securities, the  Series may not  be able  to
obtain  such securities at the price specified in such contract and thus may not
benefit from the  price differential  between the  current sales  price and  the
repurchase price.

CORPORATE ASSET-BACKED SECURITIES: Each of the Emerging Growth Series, the Total
Return Series, the Bond Series, the Limited Maturity Series, the Strategic Fixed
Income  Series, the High  Income Series and  the Utilities Series  may invest in
corporate asset-backed  securities.  These  securities,  issued  by  trusts  and
special  purpose corporations, are  backed by a  pool of assets,  such as credit
card and automobile loan receivables,  representing the obligations of a  number
of different parties.

Corporate  asset-backed securities present  certain risks. For  instance, in the
case of credit card  receivables, these securities may  not have the benefit  of
any  security interest  in the related  collateral. Credit  card receivables are
generally unsecured and the debtors are  entitled to the protection of a  number
of  state and federal consumer credit laws,  many of which give such debtors the
right to set off certain amounts owed on the credit cards, thereby reducing  the
balance  due. Most  issuers of  automobile receivables  permit the  servicers to
retain possession of the  underlying obligations. If the  servicer were to  sell
these  obligations to another  party, there is  a risk that  the purchaser would
acquire an interest superior  to that of the  holders of the related  automobile
receivables.  In addition, because of the large number of vehicles involved in a
typical issuance and technical  requirements under state  laws, the trustee  for
the  holders  of  the automobile  receivables  may  not have  a  proper security
interest in all of the obligations backing such receivables. Therefore, there is
the possibility  that recoveries  on  repossessed collateral  may not,  in  some
cases,  be available  to support  payments on  these securities.  The underlying
assets  (E.G.,  loans)  are  also  subject  to  prepayments  which  shorten  the
securities weighted average life and may lower their return.

Corporate  asset-backed  securities  are  often  backed  by  a  pool  of  assets
representing the obligations  of a number  of different parties.  To lessen  the
effect  of  failures by  obligors  on underlying  assets  to make  payments, the
securities  may  contain  elements  of  credit  support  which  fall  into   two
categories:   (i)  liquidity  protection  and  (ii)  protection  against  losses
resulting from  ultimate  default  by  an  obligor  on  the  underlying  assets.
Liquidity  protection  refers to  the provision  of  advances, generally  by the
entity administering the pool of assets, to ensure that the receipt of  payments
on  the underlying  pool occurs in  a timely fashion.  Protection against losses
resulting from ultimate  default ensures payment  through insurance policies  or
letters of credit obtained by the issuer or sponsor from third parties. A Series
will  not pay any additional or separate  fees for credit support. The degree of
credit support  provided  for  each  issue  is  generally  based  on  historical
information  respecting the level of credit  risk associated with the underlying
assets. Delinquency or  loss in  excess of that  anticipated or  failure of  the
credit  support could  adversely affect  the return on  an investment  in such a
security.

COLLATERALIZED MORTGAGE OBLIGATIONS AND MULTICLASS PASS-THROUGH SECURITIES: Each
of the Bond  Series, the Strategic  Fixed Income Series,  the World  Governments
Series,  the Limited Maturity  Series, the High Income  Series and the Utilities
Series may invest a portion of its assets in collateralized mortgage obligations
or "CMOs",  which  are debt  obligations  collateralized by  mortgage  loans  or
mortgage  pass-through securities  (such collateral referred  to collectively as
"Mortgage Assets").  Unless  the  context indicates  otherwise,  all  references
herein to CMOs include multiclass pass-through securities.

Interest  is paid or accrues on all classes  of the CMOs on a monthly, quarterly
or semi-annual basis. The principal of  and interest on the Mortgage Assets  may
be allocated among the several classes of a series of a CMO in innumerable ways.
In   a  common  structure,  payments   of  principal,  including  any  principal
prepayments, on the Mortgage Assets are applied to the classes of the series  of
a  CMO in the order of their  respective stated maturities or final distribution
dates, so that no payment of principal will  be made on any class of CMOs  until
all  other classes having an earlier  stated maturity or final distribution date
have been paid in full. Certain  CMOs may be stripped (securities which  provide
only the principal or interest factor of the underlying security). See "Stripped
Mortgage-Backed  Securities" below for a discussion of the risks of investing in
these stripped securities and of  investing in classes consisting of  principals
of interest payments or principal payments.

Each  of the  Bond Series,  the World  Governments Series,  the Limited Maturity
Series, the  High Income  Series and  the Utilities  Series may  also invest  in
parallel  pay CMOs and  Planned Amortization Class  CMOs ("PAC Bonds"). Parallel
pay CMOs are structured to provide payments of principal on each payment date to
more than  one class.  These simultaneous  payments are  taken into  account  in
calculating  the stated maturity date or  final distribution date of each class,
which, as with other CMO structures, must be retired by its stated maturity date
or final distribution date but may be retired earlier.

STRIPPED MORTGAGE-BACKED  SECURITIES: Each  of the  Bond Series,  the  Strategic
Fixed Income Series, the World Governments Series and the High Income Series may
invest a portion of its assets in

                                       3
<PAGE>
stripped  mortgage-backed  securities ("SMBS")  which are  derivative multiclass
mortgage securities  issued by  agencies  of or  instrumentalities of  the  U.S.
Government,  or  by  private originators  of,  or investors  in  mortgage loans,
including savings and  loan institutions, mortgage  banks, commercial banks  and
investment banks.

SMBS  are usually structured with two classes that receive different proportions
of the interest and  principal distributions from a  pool of mortgage assets.  A
common  type of SMBS will have one class receiving some of the interest and most
of the principal from  the Mortgage Assets, while  the other class will  receive
most  of the interest  and the remainder  of the principal.  In the most extreme
case, one class  will receive  all of the  interest (the  interest-only or  "IO"
class)   while  the  other  class  will   receive  all  of  the  principal  (the
principal-only or  "PO" class).  The yield  to maturity  on an  IO is  extremely
sensitive  to  the  rate of  principal  payments, including  prepayments  on the
related underlying Mortgage Assets, and a  rapid rate of principal payments  may
have  a material  adverse effect  on such security's  yield to  maturity. If the
underlying Mortgage Assets  experience greater than  anticipated prepayments  of
principal,  a Series may  fail to fully  recoup its initial  investment in these
securities. The market value  of the class consisting  primarily or entirely  of
principal  payments generally  is unusually volatile  in response  to changes in
interest rates. Because SMBS were only recently introduced, established  trading
markets for these securities have not yet developed, although the securities are
traded among institutional investors and investment banking firms.

LOAN  PARTICIPATIONS AND OTHER DIRECT INDEBTEDNESS:  Each of the Emerging Growth
Series, Total Return  Series, the  Strategic Fixed  Income Series  and the  High
Income Series may purchase loan participations and other direct indebtedness. In
purchasing  a loan participation, a Series acquires  some or all of the interest
of a bank or other lending institution  in a loan to a corporate borrower.  Many
such  loans are secured,  although some may  be unsecured. Such  loans may be in
default at the time  of purchase. Loans and  other direct indebtedness that  are
fully secured offer a Series 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 or other direct
indebtedness would  satisfy the  corporate borrower's  obligation, or  that  the
collateral can be liquidated.

These loans and other direct indebtedness are made generally to finance internal
growth,  mergers, acquisitions, stock repurchases,  leveraged buy-outs and other
corporate activities.  Such  loans  and  other  direct  indebtedness  loans  are
typically  made by a syndicate of  lending institutions, represented by an agent
lending institution  which  has  negotiated  and  structured  the  loan  and  is
responsible  for collecting interest, principal and other amounts due on its own
behalf and on behalf of the others  in the syndicate, and for enforcing its  and
their  other rights  against the borrower.  Alternatively, such  loans and other
direct indebtedness may be structured as a novation, pursuant to which a  Series
would  assume all of  the rights of the  lending institution in a  loan or as an
assignment, pursuant  to which  the Series  would purchase  an assignment  of  a
portion  of a lender's  interest in a  loan or other  direct indebtedness either
directly from the lender or through an intermediary. A Series may also  purchase
trade  or other claims against companies,  which generally represent money owned
by the company  to a supplier  of goods or  services. These claims  may also  be
purchased at a time when the company is in default.

Certain of the loan participations and the other direct indebtedness acquired by
a  Series may  involve revolving  credit facilities  or other  standby financing
commitments which obligate the Series to  pay additional cash on a certain  date
or  on demand. These  commitments may have  the effect of  requiring a Series to
increase its  investment in  a  company at  a time  when  the Series  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 Series is  committed to advance  additional funds, it  will at all times
hold and  maintain  in  a segregated  account  cash  or other  high  grade  debt
obligations in an amount sufficient to meet such commitments.

A  Series' ability to  receive payment of principal,  interest and other amounts
due in connection with these investments will depend primarily on the  financial
condition of the borrower. In selecting the loan participations and other direct
indebtedness  which a Series will  purchase, the Adviser will  rely upon its own
(and not the original lending institution's) credit analysis of the borrower. As
the Series may be required to  rely upon another lending institution to  collect
and pass onto the Series amounts payable with respect to the loan and to enforce
the  Series' rights under the loan and other direct indebtedness, an insolvency,
bankruptcy or reorganization of the lending institution may delay or prevent the
Series from receiving such amounts. In  such cases, the Series 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  participation
for   purposes   of   certain   investment   restrictions   pertaining   to  the
diversification of  the  Series'  portfolio investments.  The  highly  leveraged
nature  of many such loans and other direct indebtedness may make such loans and
other direct indebtedness especially vulnerable  to adverse changes in  economic
or  market conditions. Investments  in such loans  and other direct indebtedness
may involve additional risk to a Series. For example, if a loan or other  direct
indebtedness  is foreclosed, a Series could become part owner of any collateral,
and would the costs and liabilities associated with owning and disposing of  the
collateral. In addition, it is conceivable that under emerging legal theories of
lender  liability, a Series could  be held liable as  a co-lender. It is unclear
whether loans  and  other forms  of  direct indebtedness  offer  securities  law
protections  against fraud and  misrepresentation. In the  absence of definitive
regulatory guidance, each Series relies on the Adviser's research in an  attempt
to  avoid situations where fraud and  misrepresentation could adversely affect a
Series. In addition, loan participations 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
Series may be unable to sell such  investments at an opportune time or may  have
to  resell them at less  than fair market value. To  the extent that the Adviser
determines that any such investments are illiquid, a Series will include them in
the investment limitations described below.

MORTGAGE PASS-THROUGH  SECURITIES: Each  of the  Total Return  Series, the  Bond
Series,  the World Governments Series, the  Limited Maturity Series and the High
Income Series may invest in mortgage

                                       4
<PAGE>
pass-through  securities.   The  Utilities   Series  may   invest  in   mortgage
pass-through securities that are securities issued or guaranteed as to principal
and   interest   by  the   U.S.   Government,  its   agencies,   authorities  or
instrumentalities. Mortgage pass-through securities are securities  representing
interests  in  "pools"  of  mortgage loans.  Monthly  payments  of  interest and
principal by the  individual borrowers on  mortgages are passed  through to  the
holders  of the securities (net  of fees paid to the  issuer or guarantor of the
securities) as the mortgages in the underlying mortgage pools are paid off.  The
average  lives of mortgage pass-throughs are  variable when issued because their
average lives depend on prepayment rates.  The average life of these  securities
is  likely to  be substantially  shorter than their  stated final  maturity as a
result of unscheduled principal prepayment. Prepayments on underlying  mortgages
result  in a loss of anticipated  interest, and all or part  of a premium if any
has been  paid, and  the actual  yield  (or total  return) to  the Fund  may  be
different  than the quoted yield on  the securities. Mortgage premiums generally
increase with falling interest  rates and decrease  with rising interest  rates.
Like  other  fixed income  securities,  when interest  rates  rise the  value of
mortgage pass-through security  generally will decline;  however, when  interest
rates  are  declining,  the  value  of  mortgage  pass-through  securities  with
prepayment features  may not  increase as  much as  that of  other  fixed-income
securities.

Payment  of principal and interest on some mortgage pass-through securities (but
not the market value of the securities themselves) may be guaranteed by the full
faith and credit of the U.S. Government (in the case of securities guaranteed by
the Government National Mortgage Association ("GNMA"); or guaranteed by agencies
or instrumentalities  of  the U.S.  Government  (such as  the  Federal  National
Mortgage  Association ("FNMA")  or the  Federal Home  Loan Mortgage Corporation,
(FHLMC) which are  supported only  by the  discretionary authority  of the  U.S.
Government   to  purchase  the   agency's  obligations).  Mortgage  pass-through
securities may also be  issued by non-governmental  issuers (such as  commercial
banks,  savings  and loan  institutions,  private mortgage  insurance companies,
mortgage bankers and  other secondary  market issuers). Some  of these  mortgage
pass-through  securities  may  be supported  by  various forms  of  insurance or
guarantees.

Interests in pools  of mortgage-related  securities differ from  other forms  of
debt  securities, which  normally provide  for periodic  payment of  interest in
fixed amounts  with principal  payments  at maturity  or specified  call  dates.
Instead,  these  securities provide  a monthly  payment  which consists  of both
interest and principal payments. In effect, these payments are a  "pass-through"
of  the  monthly payments  made by  the individual  borrowers on  their mortgage
loans, net of  any fees  paid to  the issuer  or guarantor  of such  securities.
Additional  payments are caused  by prepayments of  principal resulting from the
sale, refinancing or  foreclosure of  the underlying  property, net  of fees  or
costs  which may  be incurred.  Some mortgage  pass-through securities  (such as
securities issued by the GNMA)  are described as "modified pass-through."  These
securities  entitle the holder  to receive all  interests and principal payments
owed on  the  mortgages in  the  mortgage pool,  net  of certain  fees,  at  the
scheduled  payment dates regardless of whether  the mortgagor actually makes the
payment.

The principal  governmental guarantor  of  mortgage pass-through  securities  is
GNMA.  GNMA is a wholly owned  U.S. Government corporation within the Department
of Housing and Urban Development. GNMA is authorized to guarantee, with the full
faith and credit  of the U.S.  Government, the timely  payment of principal  and
interest  on securities issued by institutions approved by GNMA (such as savings
and loan  institutions, commercial  banks and  mortgage bankers)  and backed  by
pools  of FHA-insured or VA-guaranteed  mortgages. These guarantees, however, do
not apply to the market value or yield of mortgage pass-through securities. GNMA
securities are  often purchased  at a  premium over  the maturity  value of  the
underlying  mortgages.  This  premium is  not  guaranteed  and will  be  lost if
prepayment occurs.

Government-related guarantors (I.E., whose guarantees are not backed by the full
faith and credit  of the  U.S. Government)  include FNMA  and FHLMC.  FNMA is  a
government-sponsored  corporation owned entirely by  private stockholders. It is
subject to general regulation by the Secretary of Housing and Urban Development.
FNMA purchases conventional residential  mortgages (I.E., mortgages not  insured
or   guaranteed  by   any  governmental   agency)  from   a  list   of  approved
seller/servicers which include  state and federally  chartered savings and  loan
associations, mutual savings banks, commercial banks, credit unions and mortgage
bankers.  Pass-through securities  issued by  FNMA are  guaranteed as  to timely
payment by FNMA of principal and interest.

FHLMC is also a government-sponsored corporation owned by private  stockholders.
FHLMC  issues Participation  Certificates ("PCs")  which represent  interests in
conventional mortgages (I.E., not federally  insured or guaranteed) for  FHLMC's
national  portfolio. FHLMC  guarantees timely  payment of  interest and ultimate
collection of  principal regardless  of the  status of  the underlying  mortgage
loans.

Commercial  banks,  savings and  loan  institutions, private  mortgage insurance
companies, mortgage  bankers  and other  secondary  market issuers  also  create
pass-through  pools of mortgage loans. Such  issuers may also be the originators
and/or servicers of the underlying mortgage-related securities. Pools created by
such non-governmental issuers  generally offer  a higher rate  of interest  than
government  and government-related pools because there are no direct or indirect
government or agency guarantees of payments in the former pools. However, timely
payment of  interest and  principal of  mortgage  loans in  these pools  may  be
supported  by  various forms  of insurance  or guarantees,  including individual
loan, title, pool and hazard insurance and letters of credit. The insurance  and
guarantees  are  issued  by  governmental  entities,  private  insurers  and the
mortgage poolers.  There  can be  no  assurance  that the  private  insurers  or
guarantors  can meet their obligations under the insurance policies or guarantee
arrangements.  A  Series  may  also  buy  mortgage-related  securities   without
insurance or guarantees.

INDEXED  SECURITIES: Each  of the Total  Return Series, High  Income Series, the
Bond Series and the  Utilities Series may purchase  securities whose prices  are
indexed  to  the prices  of  other securities,  securities  indices, currencies,
precious metals or  other commodities,  or other  financial indicators.  Indexed
securities may include securities that have embedded swap agreements (see "Swaps
and  Related Transactions"), typically,  but not always,  are debt securities or
deposits whose value at maturity or coupon rate

                                       5
<PAGE>
is determined by reference to  a specific instrument or statistic.  Gold-indexed
securities,  for example, typically provide for a maturity value that depends on
the price of gold, resulting  in a security whose price  tends to rise and  fall
together  with gold prices. 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  values  may decline
substantially if the issuer's  creditworthiness deteriorates. Recent issuers  of
indexed   securities  have  included  banks,   corporations,  and  certain  U.S.
government agencies.

SWAPS AND  RELATED TRANSACTIONS:  Each  of the  High  Income Series,  the  World
Governments  Series, the Strategic Fixed Income  Series, the Bond Series and the
Limited Maturity Series 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 Series'
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  Series is  not
limited to any particular form or variety of swap agreement if MFS determines it
is consistent with the Series' investment objective and policies.

Each  of the  High Income  Series, the  World Governments  Series, the Strategic
Fixed Income  Series, the  Bond  Series and  the  Limited Maturity  Series  will
maintain  cash  or appropriate  liquid assets  with its  custodian to  cover its
current obligations under  swap transactions.  If a  Series enters  into a  swap
agreement on a net basis (I.E., the two payment streams are netted out, with the
Series  receiving or paying, as the case may  be, only the net amount of the two
payments), the Series  will maintain cash  or liquid assets  with its  Custodian
with  a daily value at least equal to the excess, if any, of the Series' accrued
obligations under  the swap  agreement over  the accrued  amount the  Series  is
entitled  to  receive  under the  agreement.  If  a Series  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  Series' 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  is  incorrect  in  its  forecasts  of  such  factors,  the   investment
performance  of a  Series 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 Series,  the Series must  be prepared to  make such payments  when due. In
addition, if the counterparty's creditworthiness declined, the value of the swap
agreement would be likely to decline, potentially resulting in losses.

If the counterparty defaults, a Series' risk of loss consists of the net  amount
of  payments that the  Series is contractually entitled  to receive. Each Series
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.

OPTIONS  ON SECURITIES: Each  of the Emerging Growth  Series, the Growth Series,
the Total Return Series, the Bond Series, the Strategic Fixed Income Series, the
World Governments Series,  the Growth  With Income  Series and  the High  Income
Series  may write (sell) covered put and call options, and purchase put and call
options, on securities. Call and put options written by a Series may be  covered
in the manner set forth below.

A  call option written by a Series is  "covered" if the Series 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 Series 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 Series in  cash, short-term money  market instruments or  high quality  debt
securities in a segregated account with its custodian. A put option written by a
Series  is  "covered"  if the  Series  maintains cash,  short-term  money market
instruments or high-quality debt securities 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 equal to or greater than the exercise price of
the  put written or  where the exercise price  of the put held  is less than the
exercise price of the put written if the difference is maintained by the  Series
in  cash, short-term money market instruments or high-quality debt securities in
a segregated  account with  its custodian.  Put and  call options  written by  a
Series 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.

Effecting a closing transaction in the case of a written call option will permit
a  Series to write another call option  on the underlying security with either a
different exercise price or expiration date or

                                       6
<PAGE>
both, or in the  case of a written  put option will permit  the Series to  write
another  put option to the extent that  the exercise price thereof is secured by
deposited  cash,  short-term  money  market  instruments  or  high-quality  debt
securities.  Such transactions  permit a  Series to  generate additional premium
income,  which  will  partially  offset  declines  in  the  value  of  portfolio
securities  or  increases  in  the  cost of  securities  to  be  acquired. Also,
effecting a  closing transaction  will  permit the  cash  or proceeds  from  the
concurrent  sale of any  securities subject to  the option to  be used for other
investments of a Series,  provided that another option  on such security is  not
written. If a Series desires to sell a particular security from its portfolio on
which  it has  written a call  option, it  will effect a  closing transaction in
connection with the option prior to or concurrent with the sale of the security.

A Series will realize a profit from a closing transaction if the premium paid in
connection with the closing of an option written by the Series is less than  the
premium  received  from  writing  the  option, or  if  the  premium  received in
connection with the closing of an option purchased by a Series is more than  the
premium  paid for the original purchase. Conversely, a Series will suffer a loss
if the premium paid or received in connection with a closing transaction is more
or less, respectively,  than the premium  received or paid  in establishing  the
option  position. Because increases  in the market  price of a  call option will
generally reflect increases in the market price of the underlying security,  any
loss  resulting from  the repurchase  of a call  option previously  written by a
Series is  likely to  be offset  in  whole or  in part  by appreciation  of  the
underlying security owned by the Series.

The Series may write options in connection with buy-and-write transactions; that
is,  a Series may purchase a security and  then write a call option against that
security. The  exercise price  of the  call a  Series determines  to write  will
depend 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. Buy-and-write  transactions using in-the-money
call options may be used  when it is expected that  the price of the  underlying
security  will  decline  moderately  during  the  option  period.  Buy-and-write
transactions using out-of-the-money call options may be used when it is expected
that the premiums received from writing the call option plus the appreciation in
the market price of  the underlying security  up to the  exercise price will  be
greater  than the appreciation in the price of the underlying security alone. If
the call options are exercised in such transactions, a Series' maximum gain will
be the  premium received  by it  for  writing the  option, adjusted  upwards  or
downwards  by the difference between the  Series' purchase price of the security
and the exercise price, less related  transaction costs. If the options are  not
exercised  and the price of the underlying security declines, the amount of such
decline will be offset in part, or entirely, by the premium received.

The  writing  of  covered  put  options  is  similar  in  terms  of  risk/return
characteristics  to  buy-and-write  transactions.  If the  market  price  of the
underlying security rises  or otherwise  is above  the exercise  price, the  put
option  will expire worthless and a Series'  gain will be limited to the premium
received, less related transaction costs. If the market price of the  underlying
security  declines or otherwise is below the  exercise price, a Series may elect
to close the position or retain the option until it is exercised, at which  time
the  Series will be  required to take  delivery of the  security at the exercise
price; a Series' return will be the  premium received from the put option  minus
the  amount by  which the  market price  of the  security is  below the exercise
price,  which  could  result  in  a  loss.  Out-of-the-money,  at-the-money  and
in-the-money put options may be used by a Series in the same market environments
that call options are used in equivalent buy-and-write transactions.

A  Series  may also  write  combinations of  put and  call  options on  the same
security, known  as "straddles,"  with the  same exercise  price and  expiration
date.  By writing a  straddle, a Series undertakes  a simultaneous obligation to
sell and 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 Series  will be  required to  sell  the
underlying  security at a below market price.  This loss may be offset, however,
in whole or 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  the security remains stable and neither  the
call  nor the put is  exercised. In those instances 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, a Series  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 Series 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 capital  loss unless  the security
subsequently appreciates in value. The writing of options on securities will not
be undertaken by a Series solely for hedging purposes, and could involve certain
risks which are not present in the case of hedging transactions. Moreover,  even
where  options are  written for  hedging purposes,  such transactions 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.

A  Series may purchase options  for hedging purposes or  to increase its return.
Put options  may  be purchased  to  hedge against  a  decline in  the  value  of
portfolio  securities. If  such decline  occurs, the  put options  will permit a
Series to sell the securities at the exercise price, or to close out the options
at a profit. By using put options in  this way, a Series will reduce any  profit
it might otherwise have realized in the underlying security by the amount of the
premium paid for the put option and by transaction costs.

A  Series may purchase call options to hedge against an increase in the price of
securities that  the  Series  anticipates  purchasing in  the  future.  If  such
increase  occurs,  the  call  option  will permit  the  Series  to  purchase the
securities at the exercise price, or to  close out the options at a profit.  The
premium  paid for  the call  option plus any  transaction costs  will reduce the
benefit, if any, realized by a Series

                                       7

upon exercise of the  option, and, unless the  price of the underlying  security
rises sufficiently, the option may expire worthless to the Series.

In  certain instances, the Emerging Growth Series and the Strategic Fixed Income
Series may enter  into options  on U.S.  Treasury securities  which provide  for
periodic  adjustment of the strike  price and may also  provide for the periodic
adjustment of the premium during the term of each such option. Like other  types
of  options, these transactions, which may be  referred to as "reset" options or
"adjustable strike options," grant the purchaser  the right to purchase (in  the
case  of a "call") or sell (in the case of a "put"), a specified type and series
of U.S. Treasury security  at any time  up to a stated  expiration date (or,  in
certain  instances,  on  such date).  In  contrast  to other  types  of options,
however, the price  at which the  underlying security may  be purchased or  sold
under a "reset" option is determined at various intervals during the term of the
option,  and such price fluctuates from interval to interval based on changes in
the market value of the underlying security. As a result, the strike price of  a
"reset"  option,  at the  time  of exercise,  may  be less  advantageous  to the
Emerging Growth Series than if the strike price had been fixed at the initiation
of the option. In addition, the premium paid for the purchase of the option  may
be  determined at the termination, rather than the initiation, of the option. If
the premium is paid  at termination, the  Series assumes the  risk that (i)  the
premium may be less than the premium which would otherwise have been received at
the  initiation of the option because of such factors as the volatility in yield
of the underlying Treasury security over the term of the option and  adjustments
made  to  the strike  price of  the option,  and (ii)  the option  purchaser may
default on its obligation to pay the premium at the termination of the option.

OPTIONS ON STOCK INDICES: Each of the Emerging Growth Series, the Growth Series,
the Total Return Series, the Growth With Income Series and the Utilities  Series
may  write (sell) covered call and put options and purchase call and put options
on stock indices. In contrast to an option  on a security, an option on a  stock
index  provides the  holder with  the right  but not  the obligation  to make or
receive a cash settlement upon exercise of the option, rather than the right  to
purchase  or sell a security. The amount of  this settlement is equal to (i) the
amount, if any, by which the fixed exercise price of the option exceeds (in  the
case  of a call)  or is below  (in the case of  a put) the  closing value of the
underlying index on  the date  of exercise, multiplied  by (ii)  a fixed  "index
multiplier."

A  Series may  cover call  options on stock  indices by  owning securities whose
price changes, in  the opinion of  the 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 Series
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
Series 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. A Series 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  Series  in cash,  short-term  money  market  instruments or
high-quality debt  securities in  a  segregated account  with its  custodian.  A
Series  may cover put  options on stock indices  by maintaining cash, short-term
money market instruments or high-quality debt  securities with a value equal  to
the  exercise price in a segregated account  with its custodian, or by holding a
put on the same stock index 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 where the exercise price of the put held is
less than the exercise price of the put written if the difference is  maintained
by  the Series in cash, short-term money market instruments or high-quality debt
securities 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.

A  Series  will receive  a  premium from  writing a  put  or call  option, which
increases the Series' 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 Series has
written a call  option falls  or remains  the same,  the Series  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, a Series will  realize a loss in its
call  option  position,  which  will  reduce  the  benefit  of  any   unrealized
appreciation in the Series' stock investments. By writing a put option, a Series
assumes the risk of a decline in the index. To the extent that the price changes
of  securities owned  by a  Series correlate  with changes  in the  value of the
index, writing covered put options on indices will increase a Series' losses  in
the  event of a market  decline, although such losses will  be offset in part by
the premium received for writing the option.

A Series 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
Series  will seek to offset a decline in the value of securities it owns through
appreciation of the put option. If the  value of a Series' investments does  not
decline  as anticipated, or  if the value  of the option  does not increase, the
Series' 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 Series' security holdings.

The purchase of call options on stock indices may be used by a Series 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 Series holds uninvested cash  or
short-term debt securities awaiting investment. When purchasing call options for
this purpose, a Series 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 Series 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.

                                       8
<PAGE>
The  index underlying a stock index option may be a "broad-based" index, such as
the Standard & Poor's 500 Index or the New York
Stock Exchange Composite Index,  the changes in value  of which ordinarily  will
reflect  movements in the stock market  in general. In contrast, certain options
may be based  on narrower  market indices,  such as  the Standard  & Poor's  100
Index,  or on indices of securities of particular industry groups, such as those
of oil and gas or technology companies. A stock index assigns relative values to
the stocks included in the  index and the index  fluctuates with changes in  the
market values of the stocks so included. The composition of the index is changed
periodically.

YIELD  CURVE OPTIONS: Each  of the Growth  Series, the Total  Return Series, the
Bond Series, the Strategic Fixed Income Series, the World Governments Series and
the High Income Series  may also enter  into options on  the "spread," or  yield
differential,  between two fixed income  securities, in transactions referred to
as "yield curve" options. 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 prices of the individual securities, and is settled through cash
payments. Accordingly, a yield curve option is profitable to the holder if  this
differential  widens (in the case of a call)  or narrows (in the case of a put),
regardless of  whether  the yields  of  the underlying  securities  increase  or
decrease.

Yield  curve  options may  be used  for the  same purposes  as other  options on
securities. Specially, a Series may purchase  or write such options for  hedging
purposes.  For example, a Series may purchase  a call option on the yield spread
between two  securities,  if it  owns  one  of the  securities  and  anticipates
purchasing  the other security and  wants to hedge against  an adverse change in
the yield spread between the two securities. A Series may also purchase or write
yield curve  options for  other than  hedging purposes  (I.E., in  an effort  to
increase its current income) if, in the judgment of the Adviser, the Series will
be  able  to profit  from  movements in  the spread  between  the yields  of the
underlying securities. The trading of yield  curve options is subject to all  of
the  risks associated with the  trading of other types  of options. In addition,
however, such options  present risk  of loss  even if the  yield of  one of  the
underlying securities remains constant, if the spread moves in a direction or to
an  extent which was  not anticipated. Yield  curve options written  by a Series
will be "covered". A call (or put) option is covered if the Series holds another
call (or put) option on the spread between the same two securities and maintains
in a segregated account with its  custodian cash or cash equivalents  sufficient
to  cover the Series' net liability under  the two options. Therefore, a Series'
liability for  such a  covered option  is generally  limited to  the  difference
between  the amount  of the  Series' liability under  the option  written by the
Series less the value of the option held by the Series. Yield curve options  may
also  be  covered  in  such  other  manner as  may  be  in  accordance  with the
requirements of the counterparty with which the option is traded and  applicable
laws  and  regulations.  Yield  curve options  are  traded  over-the-counter and
because they have been only recently introduced, established trading markets for
these securities have not yet developed.

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 a certain
percentage of a  Series' assets  (the "SEC illiquidity  ceiling"). Although  the
Adviser  disagrees with this position, the Adviser intends to limit each Series'
writing of over-the-counter options in accordance with the following  procedure.
Except  as provided  below, a Series  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  which a Series has in place with
such primary dealers  will provide  that the Series  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 Series 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-money. A Series will treat all or a part
of the formula price as illiquid for purposes of the SEC illiquidity ceiling.  A
Series  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 SEC illiquidity ceiling.

FUTURES CONTRACTS: Each of the Bond  Series, the Strategic Fixed Income  Series,
the  World  Governments Series,  the Limited  Maturity  Series, the  High Income
Series and  the  Utilities  Series  may  purchase  and  sell  futures  contracts
("Futures  Contracts") on foreign or domestic fixed income securities or indices
of such securities. Each of the  Emerging Growth Series, the Growth Series,  the
Total  Return Series  and the  Growth With Income  Series may  purchase and sell
Futures Contracts on stock indexes, while the Emerging Growth Series, the Growth
Series, the Total Return Series, the  World Governments Series, the Growth  With
Income  Series, the Strategic  Fixed Income Series and  the Utilities Series may
purchase and sell Futures Contracts on foreign currencies or indices of  foreign
currencies. Such investment strategies will be used for hedging purposes and for
non-hedging purposes, subject to applicable law.

A  Futures Contract is a bilateral agreement providing for the purchase and sale
of a specified type and amount of a financial instrument or foreign currency, or
for the making  and acceptance of  a cash settlement,  at a stated  time in  the
future  for  a fixed  price. By  its terms,  a Futures  Contract provides  for a
specified settlement date on which, in the case of the majority of interest rate
and foreign currency futures contracts, the fixed income securities or  currency
are  delivered by the seller and paid for  by the purchaser, or on which, in the
case of stock  index futures  contracts and  certain interest  rate and  foreign
currency  futures  contracts,  the difference  between  the price  at  which the
contract was entered into  and the contract's closing  value is settled  between
the  purchaser and seller in cash. Futures Contracts differ from options in that
they are bilateral agreements,  with both the purchaser  and the seller  equally
obligated  to complete  the transaction.  Futures Contracts  call for settlement
only on the expiration date and cannot  be "exercised" at any other time  during
their term.

                                       9
<PAGE>
The  purchase or sale of a Futures Contract differs from the purchase or sale of
a security or the  purchase of an option  in that no purchase  price is paid  or
received.  Instead, an amount of cash or  cash equivalents, which varies but may
be as low as 5% or less of the value of the contract, must be deposited with the
broker as "initial margin." Subsequent payments to and from the broker, referred
to as "variation margin," are made on a daily basis as the value of the index or
instrument underlying the Futures Contract  fluctuates, making positions in  the
Futures Contract more or less valuable - a process known as "mark-to-market."

Purchases  or sales  of stock  index futures  contracts are  used to  attempt to
protect a Series' current or intended stock investments from broad  fluctuations
in stock prices. For example, a Series may sell stock index futures contracts in
anticipation  of or during a market decline to attempt to offset the decrease in
market value of the Series' securities portfolio that might otherwise result. If
such decline occurs, the loss in value of portfolio securities may be offset, in
whole or part,  by gains on  the futures position.  When a Series  is not  fully
invested  in the securities market and anticipates a significant market advance,
it may purchase  stock index  futures contracts in  order to  gain rapid  market
exposure  that  may,  in part  or  entirely,  offset increases  in  the  cost of
securities that the Series intends to purchase. As such purchases are made,  the
corresponding  positions in stock index futures contracts will be closed out. In
a substantial  majority of  these transactions,  the Series  will purchase  such
securities  upon termination of  the futures position,  but under unusual market
conditions, a long futures position may be terminated without a related purchase
of securities.

Interest rate Futures Contracts may be  purchased or sold to attempt to  protect
against  the effects of interest  rate changes on a  Series' current or intended
investments in fixed income securities. For example, if a Series owned long-term
bonds and interest rates were expected to increase, that Series might enter into
interest rate futures  contracts for the  sale of debt  securities. Such a  sale
would  have much the same effect as selling  some of the long-term bonds in that
Series' portfolio.  If  interest rates  did  increase,  the value  of  the  debt
securities  in  the  portfolio would  decline,  but  the value  of  that Series'
interest rate futures contracts would  increase at approximately the same  rate,
thereby  keeping the net asset value of that Series from declining as much as it
otherwise would have.

Similarly, if interest  rates were  expected to decline,  interest rate  futures
contracts  may be purchased to hedge  in anticipation of subsequent purchases of
long-term bonds at  higher prices. Since  the fluctuations in  the value of  the
interest  rate futures contracts should be similar to that of long-term bonds, a
Series could protect itself against the  effects of the anticipated rise in  the
value  of long-term bonds without actually  buying them until the necessary cash
became available or the market had  stabilized. At that time, the interest  rate
futures  contracts could be liquidated and that Series' cash reserves could then
be used to buy  long-term bonds on  the cash market.  A Series could  accomplish
similar  results by  selling bonds with  long maturities and  investing in bonds
with short maturities  when interest  rates are expected  to increase.  However,
since  the  futures market  is  more liquid  than the  cash  market, the  use of
interest rate futures contracts as a hedging technique allows a Series to  hedge
its interest rate risk without having to sell its portfolio securities.

As  noted in  the Prospectus,  a Series may  purchase and  sell foreign currency
futures contracts for  hedging purposes, to  attempt to protect  its current  or
intended   investments  from  fluctuations  in  currency  exchange  rates.  Such
fluctuations could reduce the dollar  value of portfolio securities  denominated
in foreign currencies, or increase the cost of foreign-denominated securities to
be  acquired, even if  the value of  such securities in  the currencies in which
they are denominated remains constant. A Series may sell futures contracts on  a
foreign  currency, for  example, where it  holds securities  denominated in such
currency and it anticipates a decline in the value of such currency relative  to
the  dollar. In the event  such decline occurs, the  resulting adverse effect on
the value of foreign-denominated securities may be offset, in whole or in  part,
by gains on the futures contracts.

Conversely,  a  Series  could protect  against  a  rise in  the  dollar  cost of
foreign-denominated securities to be acquired by purchasing futures contracts on
the relevant currency, which  could offset, in whole  or in part, the  increased
cost  of  such securities  resulting  from a  rise in  the  dollar value  of the
underlying currencies. Where  a Series  purchases futures  contracts under  such
circumstances,  however, and  the prices  of securities  to be  acquired instead
decline, the Series  will sustain  losses on  its futures  position which  could
reduce  or eliminate the benefits of the reduced cost of portfolio securities to
be acquired.

OPTIONS ON FUTURES CONTRACTS: Each Series that may buy or sell Futures Contracts
(see "Futures Contracts" above)  also may purchase and  write options to buy  or
sell  those  Futures  Contracts in  which  it  may invest  ("Options  on Futures
Contracts"). Such investment strategies  will be used  for hedging purposes  and
for non-hedging purposes, subject to applicable law.

An Option on a Futures Contract provides the holder with the right to enter into
a  "long" position  in the underlying  Futures Contract,  in the case  of a call
option, or a "short" position in the underlying Futures Contract, in the case of
a put option, at a  fixed exercise price up to  a stated expiration date or,  in
the  case of certain options,  on such date. Upon exercise  of the option by the
holder, the  contract market  clearinghouse  establishes a  corresponding  short
position  for the  writer of  the option,  in the  case of  a call  option, or a
corresponding long position in the  case of a put option.  In the event that  an
option  is exercised, the  parties will be  subject to all  the risks associated
with the trading of Futures Contracts, such as payment of initial and  variation
margin  deposits. In addition,  the writer of  an Option on  a Futures Contract,
unlike the holder, is  subject to initial and  variation margin requirements  on
the option position.

A position in an Option on a Futures Contract may be terminated by the purchaser
or  seller  prior  to  expiration  by  effecting  a  closing  purchase  or  sale
transaction, subject to the availability of a liquid secondary market, which  is
the  purchase or sale of  an option of the same  series (I.E., the same exercise
price and  expiration date)  as the  option previously  purchased or  sold.  The
difference between the premiums paid and received represents the trader's profit
or loss on the transaction.

Options  on Futures Contracts that are written  or purchased by a Series on U.S.
exchanges are  traded on  the same  contract market  as the  underlying  Futures
Contract, and, like Futures Contracts, are

                                       10
<PAGE>
subject to regulation by the Commodities Futures Trading Commission (the "CFTC")
and  the  performance  guarantee  of the  exchange  clearinghouse.  In addition,
Options on Futures Contracts may be traded on foreign exchanges.

A Series may cover the writing of call Options on Futures Contracts (a)  through
purchases  of  the underlying  Futures 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 Series in cash or securities in a segregated account with  its
custodian.  A Series may cover  the writing of put  Options on Futures Contracts
(a) through sales of the underlying Futures Contract, (b) through segregation of
cash, short-term money market instruments or high quality debt securities 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
where  the exercise price of the put held is less than the exercise price of the
put written if the  difference is maintained by  the Series in cash,  short-term
money market instruments or high quality debt securities 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 Series, the
Series will be required  to sell the underlying  Futures Contract which, if  the
Series  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 Series is  exercised, the Series will be required
to purchase the underlying Futures Contract which, if the Series has covered its
obligation through  the  sale of  such  Contract,  will close  out  its  futures
position.

The  writing  of  a call  option  on  a Futures  Contract  for  hedging purposes
constitutes a partial hedge against declining prices of the securities or  other
instruments required to be delivered under the terms of the Futures Contract. If
the  futures price at  expiration of the  option is below  the exercise price, a
Series 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 Series' portfolio holdings. The writing of a put option  on
a  Futures Contract constitutes a partial hedge against increasing prices of the
securities or other instruments required to be delivered under the terms of  the
Futures  Contract. If the  futures price at  expiration of the  option is higher
than the exercise  price, a Series  will retain  the full amount  of the  option
premium  which provides  a partial  hedge against any  increase in  the price of
securities which the  Series intends  to purchase.  If a  put or  call option  a
Series  has written  is exercised, the  Series 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 the
changes in the value  of its futures positions,  a Series' losses from  existing
Options  on Futures  Contracts may  to some  extent be  reduced or  increased by
changes in the value of portfolio securities.

The Series  may  purchase Options  on  Futures Contracts  for  hedging  purposes
instead  of 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  changes in interest or exchange rates,  a
Series  could,  in  lieu  of selling  Futures  Contracts,  purchase  put options
thereon. In the event that such decrease  occurs, it may be offset, in whole  or
in  part, by a profit on the option.  Conversely, where it is projected that the
value of  securities  to  be  acquired  by  a  Series  will  increase  prior  to
acquisition, due to a market advance or changes in interest or exchange rates, a
Series  could purchase call Options on Futures Contracts, rather than purchasing
the underlying Futures Contracts.

FORWARD CONTRACTS ON FOREIGN CURRENCY: Each  of the Emerging Growth Series,  the
Growth  Series, the Research  Series, the Total Return  Series, the Bond Series,
the Strategic Fixed Income Series, the World Governments Series, the Growth With
Income Series, the High  Income Series and the  Utilities Series may enter  into
forward foreign currency exchange contracts for hedging and non-hedging purposes
(collectively,  "Forward Contracts"). Forward Contracts  may be used for hedging
to attempt  to  minimize the  risk  to the  Fund  from adverse  changes  in  the
relationship  between the U.S. dollar and  foreign currencies. The Series intend
to enter into Forward Contracts for hedging purposes similar to those  described
above  in connection with  foreign currency futures  contracts. In particular, a
Forward Contract to sell a currency may be entered into in lieu of the sale of a
foreign currency futures  contract where a  Series seeks to  protect against  an
anticipated  increase in the  exchange rate for a  specific currency which could
reduce the dollar value  of portfolio securities  denominated in such  currency.
Conversely,  a Series  may enter  into a  Forward Contract  to purchase  a given
currency to  protect  against  a  projected increase  in  the  dollar  value  of
securities  denominated in such currency which  the Series intends to acquire. A
Series also may enter  into a Forward  Contract in order to  assure itself of  a
predetermined   exchange  rate  in  connection  with  a  fixed  income  security
denominated in  a foreign  currency.  In addition,  the  Series may  enter  into
Forward  Contracts for "cross hedging" purposes (E.G., the purchase or sale of a
Forward  Contract  on  one  type  of  currency,  as  a  hedge  against   adverse
fluctuations in the value of a second type of currency).

If  a hedging transaction in Forward Contracts is successful, the decline in the
value of portfolio securities  or other assets  or the increase  in the cost  of
securities  or other assets to  be acquired may be offset,  at least in part, by
profits on the  Forward Contract.  Nevertheless, by entering  into such  Forward
Contracts,  a Series may be required to forego  all or a portion of the benefits
which otherwise could have  been obtained from  favorable movements in  exchange
rates  or natural resources prices. The Series do not intend, in most instances,
to hold Forward Contracts entered into until maturity, at which time they  would
be  required to deliver or accept delivery  of the underlying currency, but will
usually seek  to  close  out  positions  in  such  contracts  by  entering  into
offsetting  transactions, which will serve to fix a Series' profit or loss based
upon the  value of  the contracts  at  the time  the offsetting  transaction  is
executed.

                                       11
<PAGE>
The  Series 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, a  Series may  purchase a  given foreign currency
through a Forward Contract if, in the judgment of the Adviser, the value of such
currency is expected to rise relative to the U.S. dollar. Conversely, the Series
may sell the currency  through a Forward Contract  if the Adviser believes  that
its value will decline relative to the dollar.

A  Series  entering  into  such  transactions  will  profit  if  the anticipated
movements in foreign  currency exchange  rates occurs, which  will increase  its
gross income. Where exchange rates do not move in the direction or to the extent
anticipated, however, the Series may sustain losses, which will reduce its gross
income.  Such transactions, therefore, could be considered speculative and could
involve significant risk of loss.

Each Series 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  the
Series  satisfies  this  requirement  through  segregation  of  assets,  it will
maintain, in a segregated account,  cash, cash equivalents or high-quality  debt
securities,  which will be marked to market on a daily basis, in an amount equal
to the value of its commitments  under Forward Contracts. While these  contracts
are  not presently  regulated by  the CFTC,  the CFTC  may in  the future assert
authority to regulate Forward Contracts. In  such event, the Series' ability  to
utilize Forward Contracts in the manner set forth above may be restricted.

OPTIONS  ON FOREIGN CURRENCIES:  Each of the Emerging  Growth Series, the Growth
Series, the Total  Return Series, the  Bond Series, the  Strategic Fixed  Income
Series,  the World Governments  Series, the Growth With  Income Series, the High
Income Series and the Utilities Series may purchase and write options on foreign
currencies for hedging  purposes in a  manner similar to  that in which  futures
contracts  on foreign  currencies, or Forward  Contracts, will  be utilized. 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 Series  may
purchase  put options on the foreign currency. If the value of the currency does
decline, the Series will have the right to sell such currency for a fixed amount
in dollars and will thereby offset, in whole 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, the Series 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 Series deriving from purchases of foreign currency options will 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 Series 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.

A  Series may write options on foreign  currencies for the same types of hedging
purposes. For example,  where the  Series anticipates  a decline  in the  dollar
value  of foreign-denominated securities due to adverse fluctuations in exchange
rates it could, instead of purchasing a  put option, write a call option on  the
relevant  currency. If the expected decline  occurs, the option will most likely
not be exercised, and  the diminution in value  of portfolio securities will  be
offset by the amount of the premium received.

Similarly,  instead of purchasing a call  option to hedge against an anticipated
increase in the dollar cost of securities to be acquired, a Series could write a
put option  on  the  relevant  currency  which, if  rates  move  in  the  manner
projected,  will expire unexercised and allow the Series to hedge such increased
cost up to  the amount of  the premium.  Foreign currency options  written by  a
Series  will generally be covered  in a manner similar  to the covering of other
types of options. 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, and only if rates move in the expected direction. If this
does  not occur, the option  may be exercised and a  Series 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  Series 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.

ADDITIONAL RISK FACTORS:
OPTIONS, FUTURES AND FORWARD TRANSACTIONS

RISK OF IMPERFECT CORRELATION OF  HEDGING INSTRUMENTS WITH A SERIES'  PORTFOLIO.
The  Series' ability effectively to  hedge all or a  portion of their portfolios
through  transactions  in  options,   Futures  Contracts,  Options  on   Futures
Contracts,  Forward Contracts  and options on  foreign currencies  depend on the
degree to which price movements in the underlying index or instrument  correlate
with  price movements in the relevant portion  of the Series' portfolios. In the
case of futures and options based on an index, the portfolio will not  duplicate
the  components of the  index, and 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. The  use  of Forward
Contracts for "cross hedging" purposes may involve greater correlation risks. As
a result, the correlation probably will  not be exact. Consequently, the  Series
bear  the risk that the price of  the portfolio securities being hedged will not
move in the same amount or direction as the underlying index or obligation.

For example,  if a  Series purchases  a put  option on  an index  and the  index
decreases    less   than   the    value   of   the    hedged   securities,   the

                                       12
<PAGE>
Series would experience a loss which is not completely offset by the put option.
It  is also possible that there may  be a negative correlation between the index
or obligation underlying an option or Futures Contract in which the Series has a
position and the portfolio securities the  Series is attempting to hedge,  which
could  result in  a loss on  both the  portfolio and the  hedging instrument. In
addition, a Series may enter into  transactions in Forward Contracts or  options
on  foreign  currencies in  order  to hedge  against  exposure arising  from the
currencies underlying such instruments.  In such instances,  the Series will  be
subject  to the additional risk of  imperfect correlation between changes in the
value of the currencies underlying such  forwards or options and changes in  the
value of the currencies being hedged.

It  should be noted that  stock index futures contracts  or options based upon a
narrower index of securities, such as those of a particular industry group,  may
present greater risk than options or futures based on a broad market index. This
is  due to  the fact  that a  narrower index  is more  susceptible to  rapid and
extreme fluctuations as a result  of changes in the value  of a small number  of
securities. Nevertheless, where a Series enters into transactions in options, or
futures  on narrowly-based indexes for hedging  purposes, movements in the value
of the index  should, if  the hedge is  successful, correlate  closely with  the
portion of the Series' portfolio or the intended acquisitions being hedged.

The  trading of  Futures Contracts,  options and  Forward Contracts  for hedging
purposes entails the additional risk of imperfect correlation between  movements
in  the  futures  or option  price  and the  price  of the  underlying  index or
obligation. The anticipated spread  between the prices may  be distorted due  to
the  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  options,  futures  and  forward markets.  In  this  regard,  trading  by
speculators   in  options,  futures  and  Forward  Contracts  has  in  the  past
occasionally  resulted  in  market  distortions,  which  may  be  difficult   or
impossible to predict, particularly near the expiration of such contracts.

The  trading of Options on Futures Contracts  also entails the risk that changes
in the value of the underlying Futures Contracts will not be fully reflected  in
the  value of the option. The  risk of imperfect correlation, however, generally
tends to diminish  as the maturity  date of the  Futures Contract or  expiration
date of the option approaches.

Further,  with  respect  to options  on  securities, options  on  stock indexes,
options on currencies and Options on  Futures Contracts, the Series are  subject
to  the risk of market  movements between the time  that the option is exercised
and the time of  performance thereunder. This could  increase the extent of  any
loss suffered by a Series in connection with such transactions.

In  writing a covered  call option on  a security, index  or futures contract, a
Series also incurs the risk that changes in the value of the instruments used to
cover the position will not correlate closely  with changes in the value of  the
option  or underlying index or instrument. For  example, where a Series covers a
call option written  on a stock  index through segregation  of securities,  such
securities may not match the composition of the index, and the Series may not be
fully  covered. As a result, the Series could  be subject to risk of loss in the
event of adverse market movements.

The writing of  options on securities,  options on stock  indexes or Options  on
Futures  Contracts constitutes only a partial  hedge against fluctuations in the
value of a Series' portfolio.  When a Series writes  an option, it will  receive
premium  income in return for  the holder's purchase of  the right to acquire or
dispose of  the underlying  obligation. In  the  event that  the price  of  such
obligation does not rise sufficiently above the exercise price of the option, in
the  case of a call, or fall below the exercise price, in the case of a put, the
option will  not be  exercised and  the Series  will retain  the amount  of  the
premium,  less related transaction costs, which  will constitute a partial hedge
against any decline that may have occurred in the Series' portfolio holdings  or
any increase in the cost of the instruments to be acquired.

Where  the price of the underlying obligation moves sufficiently in favor of the
holder to warrant exercise of the option, however, and the option is  exercised,
the Series will incur a loss which may only be partially offset by the amount of
the  premium  it received.  Moreover,  by writing  an  option, a  Series  may be
required to forego the benefits which might otherwise have been obtained from an
increase in the value of  portfolio securities or other  assets or a decline  in
the value of securities or assets to be acquired.

In  the event of the occurrence of any of the foregoing adverse market events, a
Series' overall return may be  lower than if it had  not engaged in the  hedging
transactions.

Those  Series  that may  enter transactions  in options  (except for  Options on
Foreign Currencies), Futures Contracts, Options on Futures Contracts and Forward
Contracts for  hedging  purposes  may  also enter  into  such  transactions  for
non-hedging  purposes.  Non-hedging  transactions  in  such  investments involve
greater risks and may result in losses  which may not be offset by increases  in
the  value of portfolio securities  or declines in the  cost of securities to be
acquired. The  Series  will  only  write covered  options,  such  that  cash  or
securities  necessary to  satisfy an option  exercise will be  segregated at all
times, unless the option is 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. Nevertheless, the  method of covering an  option employed by  a
Series  may not  fully protect it  against risk of  loss and, in  any event, the
Series could suffer losses on the option  position which might not be offset  by
corresponding  portfolio gains. Entering into transactions in Futures Contracts,
Options on  Futures  Contracts and  Forward  Contracts for  other  than  hedging
purposes could expose the Series to significant risk of loss if foreign currency
exchange rates do not move in the direction or to the extent anticipated.

With respect to the writing of straddles on securities, a Series incurs the risk
that  the price of the  underlying security will not  remain stable, that one of
the options written will be  exercised and that the  resulting loss will not  be
offset  by the  amount of the  premiums received.  Such transactions, therefore,
create an  opportunity for  increased  return by  providing  a Series  with  two
simultaneous  premiums on the same security,  but involve additional risk, since
the Series may  have an option  exercised against it  regardless of whether  the
price of the security increases or decreases.

                                       13
<PAGE>
RISK  OF A  POTENTIAL LACK OF  A LIQUID  SECONDARY MARKET. Prior  to exercise or
expiration, a futures or option position can only be terminated by entering into
a closing purchase  or sale transaction.  This requires a  secondary market  for
such  instruments on the  exchange on which the  initial transaction was entered
into. While the  Series will  enter into options  or futures  positions only  if
there  appears  to  be a  liquid  secondary  market therefor,  there  can  be no
assurance that such  a market  will exist for  any particular  contracts at  any
specific  time. In that  event, it may not  be possible to  close out a position
held by a  Series, and  the Series  could be required  to purchase  or sell  the
instrument  underlying  an option,  make or  receive a  cash settlement  or meet
ongoing variation margin requirements. Under  such circumstances, if the  Series
has  insufficient  cash  available  to  meet  margin  requirements,  it  will be
necessary to liquidate portfolio securities or other assets at a time when it is
disadvantageous to  do  so. The  inability  to  close out  options  and  futures
positions,  therefore,  could  have an  adverse  impact on  the  Series' ability
effectively to hedge their portfolios, and could result in trading losses.

The liquidity of a secondary market in a Futures Contract or option thereon  may
be  adversely  affected  by  "daily price  fluctuation  limits,"  established by
exchanges, which limit  the amount  of fluctuation in  the price  of a  contract
during  a  single trading  day. Once  the daily  limit has  been reached  in the
contract, no  trades may  be entered  into at  a price  beyond the  limit,  thus
preventing  the liquidation  of open futures  or option  positions and requiring
traders to make additional  margin deposits. Prices have  in the past moved  the
daily limit on a number of consecutive trading days.

The  trading of  Futures Contracts and  options is  also subject to  the risk of
trading  halts,  suspensions,  exchange  or  clearinghouse  equipment  failures,
government  intervention,  insolvency of  a brokerage  firm or  clearinghouse or
other disruptions  of normal  trading activity,  which could  at times  make  it
difficult  or impossible  to liquidate existing  positions or  to recover excess
variation margin payments.

MARGIN. Because  of low  initial margin  deposits  made upon  the opening  of  a
futures  or forward  position and  the writing  of an  option, such transactions
involve substantial leverage.  As a  result, relatively small  movements in  the
price  of the  contract can  result in  substantial unrealized  gains or losses.
Where a Series enters  into such transactions for  hedging purposes, any  losses
incurred  in connection therewith should, if the hedging strategy is successful,
be offset, in whole or in part, by increases in the value of securities or other
assets held by  the Series or  decreases in  the prices of  securities or  other
assets  the  Series  intends  to  acquire.  Where  a  Series  enters  into  such
transactions for other than hedging purposes, the margin requirements associated
with such transactions could expose the Series to greater risk.

TRADING AND  POSITION LIMITS.  The exchange  on which  futures and  options  are
traded  may impose limitations governing the  maximum number of positions on the
same side of the market and  involving the same underlying instrument which  may
be  held by a  single investor, whether  acting alone or  in concert with others
(regardless of  whether  such  contracts  are held  on  the  same  or  different
exchanges  or held  or written in  one or more  accounts or through  one or more
brokers). Further, the CFTC  and the various  contract markets have  established
limits  referred to as "speculative position limits"  on the maximum net long or
net short position which any person may hold or control in a particular  futures
or  option contract. An exchange may order the liquidation of positions found to
be  in  violation  of  these  limits  and  it  may  impose  other  sanctions  or
restrictions.  The  Adviser does  not believe  that  these trading  and position
limits will have any adverse impact on the strategies for hedging the portfolios
of the Series.

RISKS OF OPTIONS ON FUTURES CONTRACTS. The amount of risk a Series assumes  when
it purchases an Option on a Futures Contract is the premium paid for the option,
plus  related transaction  costs. In order  to profit from  an option purchased,
however, it  may  be necessary  to  exercise the  option  and to  liquidate  the
underlying  Futures  Contract, subject  to the  risks of  the availability  of a
liquid offset market  described herein.  The writer of  an Option  on a  Futures
Contract  is subject  to the risks  of commodity futures  trading, including the
requirement of initial and variation margin payments, as well as the  additional
risk  that movements in the price of the option may not correlate with movements
in the price of the underlying security, index, currency or Futures Contract.

RISKS OF  TRANSACTIONS  RELATED  TO  FOREIGN  CURRENCIES  AND  TRANSACTIONS  NOT
CONDUCTED  ON  U.S.  EXCHANGES.  Transactions in  Forward  Contracts  on foreign
currencies,  as  well  as  futures   and  options  on  foreign  currencies   and
transactions   executed  on  foreign  exchanges,  are  subject  to  all  of  the
correlation, liquidity and  other risks  outlined above.  In addition,  however,
such  transactions are  subject to  the risk  of governmental  actions affecting
trading in or the  prices of currencies underlying  such contracts, which  could
restrict or eliminate trading and could have a substantial adverse effect on the
value  of positions held by a Series. Further, the value of such positions could
be adversely  affected by  a  number of  other  complex political  and  economic
factors applicable to the countries issuing the underlying currencies.

Further,  unlike  trading  in  most  other types  of  instruments,  there  is no
systematic reporting  of  last sale  information  with respect  to  the  foreign
currencies  underlying contracts thereon. As a result, the available information
on which trading systems will be based may not be as complete as the  comparable
data on which a Series makes investment and trading decisions in connection with
other  transactions. Moreover, because the foreign  currency market is a global,
24-hour market, events could occur in that market which will not be reflected in
the forward, futures or options market  until the following day, thereby  making
it more difficult for the Series to respond to such events in a timely manner.

Settlements  of  exercises  of  over-the-counter  Forward  Contracts  or foreign
currency options generally must occur within the country issuing the  underlying
currency,  which in  turn requires  traders to accept  or make  delivery of such
currencies in conformity with any  U.S. or foreign restrictions and  regulations
regarding the maintenance of foreign banking relationships, fees, taxes or other
charges.

Unlike  transactions  entered  into  by  the  Series  in  Futures  Contracts and
exchange-traded options, options  on foreign currencies,  Forward Contracts  and
over-the-counter  options  on  securities  are not  traded  on  contract markets
regulated by  the  CFTC or  (with  the  exception of  certain  foreign  currency
options) the SEC. To the

                                       14
<PAGE>
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.   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.

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
Series'  position unless  the institution  acts as  broker and  is able  to find
another counterparty  willing to  enter into  the transaction  with the  Series.
Where no such counterparty is available, it will not be possible to enter into a
desired transaction. There also may be no liquid secondary market in the trading
of  over-the-counter contracts, and a Series could be required to retain options
purchased or  written,  or  Forward  Contracts  entered  into,  until  exercise,
expiration  or maturity. This in turn could  limit the Series' ability to profit
from open positions or to reduce losses experienced, and could result in greater
losses.

Further, over-the-counter transactions are  not subject to  the guarantee of  an
exchange  clearinghouse, and a Series  will therefore be subject  to the risk of
default by,  or the  bankruptcy of,  the financial  institution serving  as  its
counterparty.  One or more  of such institutions also  may decide to discontinue
their role  as  market-makers in  a  particular currency  or  security,  thereby
restricting  the Series' ability  to enter into  desired hedging transactions. A
Series will enter into an  over-the-counter transaction only with parties  whose
creditworthiness has been reviewed and found satisfactory by the Adviser.

Options  on securities, options on stock  indexes, Futures Contracts, Options on
Futures Contracts and options on foreign  currencies may be traded on  exchanges
located in foreign countries. Such transactions 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.

Options on foreign currencies traded on national securities exchanges are within
the jurisdiction of the SEC, as  are other securities traded on such  exchanges.
As  a result, many of the protections provided to traders on organized exchanges
will be available with respect to such transactions. In particular, all  foreign
currency  option positions  entered into on  a national  securities exchange are
cleared and guaranteed by the Options Clearing Corporation (the "OCC"),  thereby
reducing the risk of counterparty default. Further, a liquid secondary market in
options  traded on a national securities  exchange may be more readily available
than  in  the  over-the-counter  market,  potentially  permitting  a  Series  to
liquidate  open positions  at a  profit prior to  exercise or  expiration, or to
limit losses in the event of adverse market movements.

The purchase and sale of  exchange-traded foreign currency options, however,  is
subject  to the risks of the availability of a liquid secondary market described
above, as well  as the risks  regarding adverse market  movements, margining  of
options   written,  the  nature   of  the  foreign   currency  market,  possible
intervention by governmental authorities and the effects of other political  and
economic  events.  In addition,  exchange-traded  options on  foreign currencies
involve certain risks not presented by the over-the-counter market. For example,
exercise and settlement  of such options  must be made  exclusively through  the
OCC, which has established banking relationships in applicable foreign countries
for  this  purpose. As  a result,  the OCC  may, if  it determines  that foreign
governmental restrictions  or  taxes would  prevent  the orderly  settlement  of
foreign  currency option exercises, or would result  in undue burdens on the OCC
or its clearing member,  impose special procedures  on exercise and  settlement,
such  as technical changes in the mechanics  of delivery of currency, the fixing
of dollar settlement prices or prohibitions on exercise.

POLICIES ON THE USE  OF FUTURES AND  OPTIONS ON FUTURES  CONTRACTS. In order  to
assure  that the Series will not be deemed to be a "commodity pool" for purposes
of the Commodity  Exchange Act, regulations  of the CFTC  require that a  Series
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  the Series'  assets. In  addition,  the Series  must comply  with the
requirements  of  various  state  securities   laws  in  connection  with   such
transactions.

Each Series 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  such Series' total assets. Moreover, a Series 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 a Series purchases a Futures Contract, an amount of cash or securities will
be  deposited in  a segregated  account with  the Series  custodian so  that the
amount so segregated will at all times equal the value of the Futures  Contract,
thereby insuring that the use of such futures is unleveraged.

RISKS OF INVESTING IN LOWER RATED BONDS

Each  of the Emerging Growth  Series, the Growth Series,  the Growth With Income
Series, the  Research Series,  the Total  Return Series,  the Bond  Series,  the
Limited  Maturity Series,  the Strategic  Fixed Income  Series, the  High Income
Series and the Utilities Series may invest in fixed income securities rated  Baa
by  Moody's  Investors Service,  Inc. ("Moody's")  or BBB  by Standard  & Poor's
Ratings Group ("S&P") or Fitch Investors Service, Inc. ("Fitch") and  comparable
unrated   securities.  These  securities,  while  normally  exhibiting  adequate
protection parameters, have speculative

                                       15
<PAGE>
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 of these  Series (except the  Limited Maturity Series)  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 (commonly known as "junk bonds") to  the
extent  described in the  Prospectus. No minimum rating  standard is required by
the Series. These  securities are  considered speculative  and, while  generally
providing  greater  income 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 reflect 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  fixed income  securities are  also
affected  by changes in interest  rates). In the past,  economic downturns or an
increase in interest rates  have, under certain  circumstances, caused a  higher
incidence  of default by  the issuers of these  securities and may  do so in the
future, especially in the case of highly leveraged issuers. 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 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 may  refer to  ratings issued  by established  credit rating
agencies, it is not the Series' policy to rely exclusively on ratings issued  by
these  rating agencies, but rather to supplement such ratings with the Adviser's
own independent and ongoing review of  credit quality. To the extent the  Series
invests  in  these lower  rated securities,  the  achievement of  its investment
objectives may be more  dependent on the Adviser's  own credit analysis than  in
the  case of a fund  investing in higher quality  fixed income securities. These
lower rated securities  may also  include zero coupon  bonds, deferred  interest
bonds and PIK bonds.

FOREIGN SECURITIES:

The  Limited  Maturity  Series  may invest  in  dollar-denominated  foreign debt
securities. The Money  Market Series  may invest  in the  securities of  foreign
issuers  and  in the  securities  of foreign  branches  of U.S.  banks,  such as
negotiable certificates  of  deposit  (Eurodollars). The  remaining  Series  may
invest  in dollar-denominated and non  dollar-denominated foreign securities. As
discussed  in  the  Prospectus,   investing  in  foreign  securities   generally
represents a greater degree of risk than investing in domestic securities due to
possible  exchange rate fluctuations, less  publicly available information, more
volatile markets, less securities regulation, less favorable tax provisions, war
or expropriation. As a result of its investments in foreign securities, a Series
may receive  interest or  dividend payments,  or  the proceeds  of the  sale  or
redemption of such securities,in the foreign currencies in which such securities
are denominated. Under certain circumstances, such as where the Adviser believes
that  the applicable exchange rate is unfavorable at the time the currencies are
received or the  Adviser anticipates, for  any other reason,  that the  exchange
rate will improve, a Series may hold such currencies for an indefinite period of
time.  While the holding of currencies will permit a Series to take advantage of
favorable movements in the applicable exchange rate, such strategy also  exposes
the  Series to risk of loss if exchange rates move in a direction adverse to the
Series' position. Such losses  could reduce any profits  or increase any  losses
sustained  by the  Series from  the sale or  redemption of  securities and could
reduce the dollar value of interest or dividend payments received.

AMERICAN DEPOSITARY RECEIPTS

Each of  the Series  except the  Limited Maturity  Series and  the Money  Market
Series   may  invest  in   American  Depositary  Receipts   ("ADRs")  which  are
certificates issued  by a  U.S.  depositary (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. A Series 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. A  Series 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 Series' custodian in  five days. A Series 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 the 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 foreign currency.

PORTFOLIO TRADING

The  Emerging Growth Series,  the Growth Series, the  Research Series, the Total
Return Series, the Bond  Series, the Strategic Fixed  Income Series, the  Growth
With  Income Series, the Limited Maturity Series, the High Income Series and the
Utilities Series expect to have  a portfolio turnover rate  of up to    %,    %,
  %,      %,     %,     %,     %,     %,     %,  and     %  respectively, during

                                       16

the current fiscal year. The World  Governments Series has a portfolio  turnover
rate of 62% for the fiscal year ended December 31, 1994.
                              -------------------

A  Series' limitations, policies and ratings  restrictions 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.

3.  INVESTMENT RESTRICTIONS

Each  Series  has adopted  the following  restrictions  which cannot  be changed
without the approval of the holders of a majority of the Series' shares  (which,
as  used in this  Statement of Additional  Information, means the  lesser of (i)
more than 50% of the outstanding shares of the Trust or a Series, as applicable,
or (ii) 67%  or more  of the outstanding  shares of  the Trust or  a Series,  as
applicable,  present at a meeting if holders of more than 50% of the outstanding
shares of the Trust or a Series, as applicable, are represented in person or  by
proxy). Except for Investment Restriction (1), these investment restrictions and
policies  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 any of the restrictions.

The Trust, on behalf of any Series, may not:

                                  (1)
        borrow    amounts    in   excess    of   33    1/3%   of    its   assets
including  amounts  borrowed  and   then  only  as   a  temporary  measure   for
  extraordinary or emergency purposes;

                                  (2)
        underwrite securities issued by other persons except
  insofar  as  the Series  may technically  be deemed  an underwriter  under the
  Securities Act of  1933, as amended  (the "1933 Act")  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  currencies  and any  type  of
  option, Futures Contracts and Forward Contracts) in the ordinary course of its
  business.  The Series reserves the freedom of  action to hold and to sell real
  estate,  mineral  leases,  commodities   or  commodity  contracts   (including
  currencies  and any type  of option, Futures  Contracts 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 swap,  option, Forward Contracts and Futures  Contracts
  and  collateral arrangements with respect to  initial and variation margin are
  not deemed to be the issuance of a senior security;

        make   loans    to   other(5) persons.   For    these   purposes,    the
  purchase  of 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
  Series' 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 gross assets would be invested
  in securities of issuers whose principal  business activities are in the  same
  industry (except (i) there is no limitation with respect to obligations issued
  or guaranteed by the U.S. Government or its agencies and instrumentalities and
  repurchase agreements collateralized by such obligations, (ii) the High Income
  Series  may invest  up to  40% of  its gross  assets in  each of  the electric
  utility and telephone industries, (iii) the Money Market Series may invest  up
  to  75% of its assets in all finance  companies as a group, all banks and bank
  holding companies as a group and all utility companies as a group when in  the
  opinion  of management yield differentials and money market conditions suggest
  and when cash is available for  such investment and instruments are  available
  for  purchase which  fulfill that  Series' objective  in terms  of quality and
  marketability, (iv) the Strategic Fixed Income Series may invest up to 40%  of
  its  assets in each of  the electric utility and  telephone industries and (v)
  the Utilities Series  will invest  at least  25% of  its gross  assets in  the
  utilities industry).

In addition, each Series has adopted the following nonfundamental policies which
may  be changed by the vote of the Trust's Board of Trustees without shareholder
approval. The Trust, on behalf of any Series, 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 Series' assets (taken at market value)  (10% of assets in the case of  the
  Money  Market  Series)  would  be  invested  in  such  securities.  Repurchase
  agreements maturing in more than seven days will be deemed to be illiquid  for
  purposes  of  the Series'  limitation  on investment  in  illiquid securities.
  Securities that are not registered under the 1933 Act 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% (10% in the case of
  the Money Market Series) limitation;

                                  (2)
        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;

                                  (3)
        purchase    any   securities   or    evidences   of   interest   therein
  on margin, except that the Series may obtain such short-term credit as may  be
  necessary  for the clearance of any transaction and except that the Series may
  make margin deposits  in connection  with any  type of  swap, option,  Futures
  Contracts and Forward Contracts;

                                  (4)
        sell   any   security   which   the   Series   does   not   own   unless
  by virtue of its ownership of other  securities the Series 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;

                                       17
<PAGE>
                                  (5)
        pledge,   mortgage   or   hypothecate   in   excess   of   33   1/3%  of
  its gross assets.  For purposes of  this restriction, collateral  arrangements
  with  respect  to any  type  of swap,  option,  Futures Contracts  and Forward
  Contracts  and  payments  of  initial  and  variation  margin  in   connection
  therewith, are not considered a pledge of assets;

                                  (6)
        purchase    or    sell    any    put    or    call    option    or   any
combination  thereof,  provided  that  this  shall  not  prevent  the  purchase,
  ownership,  holding or sale of (i) warrants  where the grantor of the warrants
  is the issuer  of the underlying  securities or  (ii) put or  call options  or
  combinations thereof with respect to securities, indices of securities, swaps,
  foreign currencies and Futures Contracts;

                                  (7)
        invest for the purpose of exercising control or
  management;

                                  (8)
        hold    obligations   issued    or   guaranteed   by    any   one   U.S.
  Governmental agency or instrumentality, at the end of any calendar quarter (or
  within 30 days thereafter), to the extent such holdings would cause the Series
  to fail to  comply with  the diversification requirements  imposed by  Section
  817(h)  of the Internal Revenue Code of 1986, as amended (the "Code"), and the
  Treasury regulations issued thereunder on segregated asset accounts that  fund
  variable contracts.

 Boston, Massachusetts 02116.

Mr.  Brodkin and each officer hold  comparable positions with certain affiliates

The Trust pays the compensation of  non-interested Trustees (who will receive  a
fee  of $     per  year plus $      per meeting and  committee meeting attended,
together with such trustee's out-of-pocket expenses.

Set forth  in  Exhibit A  hereto  is  certain information  concerning  the  cash
compensation paid to non-interested Trustees.

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 liabilities of  the Trust or its  shareholders, it is finally  adjudicated
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 interest of the Trust.  In
the  case of settlement, such indemnification will not be provided unless it has
been determined pursuant  to the  Declaration of  Trust, that  such officers  or
Trustees have not engaged in willful misfeasance, bad faith, gross negligence or
reckless disregard of their duties.

INVESTMENT ADVISER

MFS  and its predecessor organizations have a history of money management dating
from 1924. MFS is a subsidiary of  Sun Life Assurance Company of Canada  (U.S.),
which  in turn  is a subsidiary  of Sun  Life Assurance Company  of Canada ("Sun
Life").

INVESTMENT ADVISORY AGREEMENT

MFS manages  the  assets of  each  Series  pursuant to  an  Investment  Advisory
Agreement  with the Trust  on behalf of each  Series dated as  of April 14, 1994
(the "Advisory  Agreement"). MFS  provides the  Series with  overall  investment
advisory  and  administrative services,  as well  as general  office facilities.
Subject to such  policies as the  Trustees may determine,  MFS makes  investment
decisions for

                                       18
<PAGE>
the  Series. For these  services and facilities, the  Adviser receives an annual
management fee, computed and paid monthly, as disclosed in the Prospectus  under
the heading "Management of the Series."

For the Fund's fiscal year ended December 31, 1994, MFS received management fees
under  the  Advisory Agreement  of $7,604.  Pursuant  to the  reimbursement plan
discussed in  the Expense  Summary  section of  the  prospectus for  its  fiscal
year-ended  December  31,  1994,  MFS reimbursed  the  World  Governments Series
$36,473.

In order to  comply with  the expense  limitations of  certain state  securities
commissions,  MFS will reduce its management fee or otherwise reimburse a Series
for any  expenses,  exclusive  of interest,  taxes  and  brokerage  commissions,
incurred by the Series in any fiscal year to the extent such expenses exceed the
most  restrictive of such  state expense limitations.  MFS will make appropriate
adjustments to such reductions and  reimbursements in response to any  amendment
or rescission of the various state requirements.

MFS  pays the compensation of the Trust's officers  and of any Trustee who is an
officer  of  MFS.  MFS  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  Series'  investments,  effecting  its  portfolio
transactions and, in general, administering its affairs.

The Advisory Agreement  with the  Trust will remain  in effect  until August  1,
1995,  and will continue in effect thereafter with respect to any Series only if
such continuance is  specifically approved  at least  annually by  the Board  of
Trustees  or  by  vote  of a  majority  of  the Series'  shares  (as  defined in
"Investment 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. The Advisory Agreement terminates automatically if it is assigned and may
be terminated with respect to any Series  without penalty by vote of a  majority
of  the Series'  shares (as defined  in "Investment Restrictions")  or by either
party on not  more than  60 days'  nor less than  30 days'  written notice.  The
Advisory  Agreement with respect to  each Series provides that  if MFS ceases to
serve as the investment adviser to the  Series, the Series will change its  name
so  as to delete the term  "MFS" and that MFS may  render services to others and
may permit other fund clients to use the term "MFS" in their names. The Advisory
Agreement also provides that neither MFS  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
Series,  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.

CUSTODIAN

Investors Bank & Trust Company (the "Custodian") is the custodian of the Trust's
assets.  The  Custodian's responsibilities  include safekeeping  and controlling
each  Series'  cash  and  securities,  handling  the  receipt  and  delivery  of
securities,  determining  income  and  collecting interest  and  dividends  on a
Series' 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 shares  of the  Series.  The Custodian  does not  determine  the
investment policies of the Series or decide which securities the Series will buy
or sell. Each Series may, however, invest in securities of the Custodian and may
deal  with the Custodian as principal  in securities transactions. The Custodian
has contracted with MFS for MFS to perform certain accounting functions  related
to  certain transactions for  which the Adviser receives  remuneration on a cost
basis.  State  Street  Bank  and  Trust  Company  serves  as  the  dividend  and
distribution disbursing agent of the Series.

SHAREHOLDER SERVICING AGENT

MFS  Service Center,  Inc. (the  "Shareholder Servicing  Agent"), a wholly-owned
subsidiary of MFS and a registered  transfer agent, is each Series'  shareholder
servicing  agent, pursuant to  a Shareholder Servicing  Agent Agreement with the
Trust on  behalf  of  the Series,  dated  as  of April  14,  1994  (the  "Agency
Agreement"). 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
shares  of the Series. For these  services, the Shareholder Servicing Agent will
receive a fee based on the net assets of each Series, computed and paid monthly.
In addition, the Shareholder Servicing Agent will be reimbursed by a Series  for
certain  expenses incurred by  the Shareholder Servicing Agent  on behalf of the
Series. For  the  fiscal  year  ended  December 31,  1994,  the  Fund  paid  the
Shareholder  Servicing  Agent fees  of $992  under  the Agency  Agreement. State
Street Bank and Trust  Company, the dividend  and distribution disbursing  agent
for  the  Series,  has  contracted  with  the  Shareholder  Servicing  Agent  to
administer and perform  certain dividend and  distribution disbursing  functions
for the Series.

DISTRIBUTOR

MFD,  a  wholly-owned  subsidiary of  MFS,  serves  as the  distributor  for the
continuous offering of shares of the Trust pursuant to a Distribution  Agreement
dated as of April 14, 1994 (the "Distribution Agreement").

As  agent, MFD currently offers  shares of each Series  on a continuous basis to
the separate  accounts of  Participating Insurance  Companies in  all states  in
which  the Series  or the  Trust may from  time to  time be  registered or where
permitted by  applicable  law.  The Distribution  Agreement  provides  that  MFD
accepts  orders for shares at net asset value  as no sales commission or load is
charged. MFD has made no firm commitment to acquire shares of any Series.

The Distribution Agreement will remain in  effect until August 1, 1995 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 Restrictions") and in either case, by
a majority of the Trustees who are not parties to such 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.

5.  PORTFOLIO TRANSACTIONS AND BROKERAGE
COMMISSIONS

Specific decisions  to purchase  or sell  securities for  a Series  are made  by
employees  of  MFS, who  are appointed  and supervised  by its  senior officers.
Changes in a Series' investments are reviewed by the Trust's Board of  Trustees.
A  Series' portfolio manager may serve other clients of MFS or any subsidiary of
MFS in a similar capacity.

The primary  consideration  in  placing  portfolio  security  transactions  with
broker-dealers  for  execution is  to obtain  and  maintain the  availability of
execution at  the  most  favorable  prices and  in  the  most  effective  manner
possible.  MFS has complete freedom as to  the markets in and the broker-dealers
through which  it seeks  this result.  MFS attempts  to achieve  this result  by
selecting  broker-dealers  to execute  portfolio transactions  on behalf  of the
Series and other clients of MFS  on the basis of their professional  capability,
the  value  and quality  of their  brokerage  services, and  the level  of their
brokerage  commissions.  In  the  case  of  securities,  such  as  fixed  income
securities, which are principally traded in the over-the-counter market on a net
basis  through dealers acting for their own account and not as brokers (where no
stated commissions  are  paid  but  the prices  include  a  dealer's  markup  or
markdown),  MFS normally seeks to deal  directly with the primary market makers,
unless in its  opinion, better prices  are available elsewhere.  In the case  of
securities  purchased from underwriters,  the cost of  such securities generally
includes a  fixed underwriting  commission or  concession. Securities  firms  or
futures  commission merchants may receive  brokerage commissions on transactions
involving options, Futures Contracts  and Options on  Futures Contracts and  the
purchase  and  sale  of  underlying securities  upon  exercise  of  options. The
brokerage  commissions  associated  with  buying  and  selling  options  may  be
proportionately   higher   than   those  associated   with   general  securities
transactions. From time to time, soliciting dealer fees are available to MFS  on
the  tender of  a Series' portfolio  securities in so-called  tender or exchange
offers. Such soliciting dealer fees are  in effect recaptured for the Series  by
MFS. At present no other recapture arrangements are in effect.

Under  the  Advisory  Agreements  and  as  permitted  by  Section  28(e)  of the
Securities Exchange Act of  1934, as amended,  MFS may cause a  Series to pay  a
broker-dealer which provides brokerage and research services to MFS an amount of
commission  for effecting a securities transaction for a Series in excess of the
amount other  broker-dealers  would have  charged  for the  transaction  if  MFS
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 MFS's
overall responsibilities to the Series or to its other clients. Not all of  such
services are useful or of value in advising a Series.

The  term "brokerage and research  services" includes advice as  to the value of
securities, the  advisability  of  purchasing or  selling  securities,  and  the
availability  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.

Although  commissions paid on every transaction will, in the judgment of MFS, 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  the
Series'  and  MFS's  other  clients  in part  for  providing  advice  as  to the
availability 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 MFS  for no  consideration other  than
brokerage  or underwriting commissions. Securities may be bought or sold through
such broker-dealers, but at  present, unless otherwise directed  by a Series,  a
commission  higher than one  charged elsewhere will  not be paid  to such a firm
solely because it  provided Research  to MFS.  The Trustees  (together with  the
Trustees  of  the other  MFS Funds)  have directed  MFS to  allocate a  total of
$20,000 of  commission business  from  the various  MFS  Funds to  the  Pershing
Division of Donaldson, Lufkin & Jenrette as consideration for the annual renewal
of  the Lipper  Directors' Analytical  Data Service  (which provides information
useful to the Trustees in reviewing the relationship between each Fund and MFS).

The investment management personnel  of MFS attempt to  evaluate the quality  of
Research  provided by brokers. Results of this  effort are sometimes used by MFS
as  a  consideration  in   the  selection  of   brokers  to  execute   portfolio
transactions. However, MFS is unable to quantify the amount of commissions which
will  be  paid as  a result  of such  Research because  a substantial  number of
transactions will be effected through  brokers which provide Research but  which
were selected principally because of their execution capabilities.

The  management  fee that  each Series  pays to  MFS  will not  be reduced  as a
consequence of the  receipt of brokerage  and research services  by MFS. To  the
extent  a Series' portfolio  transactions are used to  obtain such services, the
brokerage commissions paid by the Series will exceed those that might  otherwise
be  paid, by an amount which cannot be presently determined. Such services would
be useful and of value  to MFS in serving both  a Series and other clients  and,
conversely,  such services  obtained by the  placement of  brokerage business of
other clients would  be useful to  MFS in  carrying out its  obligations to  the
Series.  While such services are not expected to reduce the expenses of MFS, MFS
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 Series'
portfolio as well  as for  that of  one or  more of  the other  clients of  MFS.
Investment  decisions for a  Series 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

                                       20
<PAGE>
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 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  Series is  concerned. In  other  cases, however,  it  is
believed  that  a Series'  ability to  participate  in volume  transactions will
produce better executions for the Series.

6.  TAX STATUS

Shares of  the  Series  are  offered  only  to  the  separate  accounts  of  the
Participating  Insurance  Companies  that  fund  Contracts.  See  the applicable
Contract prospectus for a discussion of the special taxation of those  companies
with respect to those accounts and of the Contract holders.

Each Series of the Trust intends to elect and qualify each year for treatment 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  each Series'  gross
income,  the  amount  of each  Series'  distributions, and  the  composition and
holding period of each Series' portfolio assets. Because each Series intends  to
distribute all of its net investment income and net realized capital and foreign
currency  gains to shareholders in accordance  with the timing and certain other
requirements imposed by the Code, it is not expected that any of the Series will
be required to pay any federal income  or excise taxes, although a Series  which
has foreign-source income may be subject to foreign withholding taxes. If any of
the  Series should fail  to qualify as  a "regulated investment  company" in any
year, that Series would  incur a regular corporate  federal income tax upon  its
taxable income.

Each Series intends to diversify its assets as required by section 817(h) of the
Code  and the regulations thereunder. These  requirements, which are in addition
to the diversification requirements of  Subchapter M, place certain  limitations
on  the proportion of each Series' assets  that may be represented by any single
investment and securities  from the same  issuer. For these  purposes each  U.S.
Government  agency or instrumentality  is treated as a  separate issuer, while a
particular foreign government and its agencies, instrumentalities and  political
subdivisions  all are considered one  issuer. If a Series  should fail to comply
with these requirements, variable annuity and variable life insurance  contracts
that  invest in the  Series would not  be treated as  annuity, endowment or life
insurance contracts under the Code.

Distributions of  net capital  gains,  whether made  in  cash or  in  additional
shares, are taxable to shareholders as long-term capital gains without regard to
the   length  of  time   the  shareholders  have   held  their  shares.  Certain
distributions of a Series which are declared in October, November, or  December,
to  shareholders of record in such month and paid the following January, will be
taxable to shareholders as if received on December 31 of the year in which  they
are declared.

Any  investment  by a  Series  in zero  coupon  bonds, deferred  interest bonds,
payment-in-kind bonds,  certain  stripped  securities,  and  certain  securities
purchased  at a market discount will cause  the Series 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 Series, the Series may be required
to  liquidate portfolio  securities that  it might  otherwise have  continued to
hold.

A Series' transactions in options, Futures Contracts, Forward Contracts, foreign
currencies, swaps  and  related  transactions,  to  the  exent  allowed  by  its
investment  objectives, will be subject to special tax rules that may affect the
amount,  timing,  and   character  of   Series  income   and  distributions   to
shareholders.  For  example, certain  positions  held by  a  Series 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, as
well as  gain or  loss associated  with  such positions  closed out  during  the
taxable  year, will be treated as 60%  long-term and 40% short-term capital gain
or loss. Certain positions held by a Series 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 Series losses, adjustments in the  holding periods of Series securities,  and
conversion  of short-term into  long-term capital losses.  Certain tax elections
exist for straddles which may alter the effects of these rules. Each Series will
limit its  activities  in  options, Futures  Contracts,  Forward  Contracts  and
foreign  currencies  to  the  extent  necessary  to  meet  the  requirements  of
Subchapter M of the Code.

Special tax  considerations apply  with  respect to  a  Series that  invests  in
foreign  securities. Foreign  exchange gains and  losses realized  by the Series
will generally  be  treated  as  ordinary income  and  losses.  Use  of  foreign
currencies  for non-hedging purposes may be limited in order to avoid a tax on a
Series. Investment by a Series in certain "passive foreign investment companies"
may also be limited in order to avoid a tax on the Series.

Investment income received by a Series from sources within foreign countries 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  Series
to  a reduced rate of tax  or an exemption from tax  on such income; the Series'
intend to qualify for treaty reduced rates where available. It is not  possible,
however,  to determine a Series  effective rate of foreign  tax in advance since
the amount of the Series' assets to be invested within various countries is  not
known.

7.  NET INCOME AND DISTRIBUTIONS

MONEY  MARKET SERIES: The net income attributable  to the Money Market Series is
determined each day during which  the Exchange is open  for trading. (As of  the
date  of  this Statement  of Additional  Information, the  Exchange is  open for
trading every weekday except  for the following holidays  (or the days on  which
they are

                                       21
<PAGE>
observed):   New  Year's  Day,  Presidents'  Day,  Good  Friday,  Memorial  Day,
Independence Day, Labor  Day, Thanksgiving  Day, Christmas  Day.) (For  taxation
information on distributions, see "Tax Status" above.)

For  this purpose,  the net  income attributable to  shares of  the Money Market
Series (from the time of the immediately preceding determination thereof)  shall
consist  of (i) all interest income accrued on the portfolio assets of the Money
Market Series, (ii) less all actual and accrued expenses of Money Market  Series
determined  in  accordance with  generally  accepted accounting  principles, and
(iii)  plus  or  minus  net  realized  gains  and  losses  and  net   unrealized
appreciation  or depreciation on the assets of the Money Market Series. Interest
income shall include discount earned  (including both original issue and  market
discount) on discount paper accrued ratably to the date of maturity.

Since  the net  income is  declared as a  dividend each  time the  net income is
determined, the net asset value per share (I.E., the value of the net assets  of
the  Money Market Series divided by the number of shares outstanding) remains at
$1.00  per  share  immediately  after  each  such  determination  and   dividend
declaration.   Any  increase  in  the   value  of  a  shareholder's  investment,
representing the reinvestment of dividend income, is reflected by an increase in
the number of shares in its account.

It is expected the shares  of the Money Market Series  will have a positive  net
income  at the  time of each  determination thereof.  If for any  reason the net
income determined  at any  time is  a negative  amount, which  could occur,  for
instance,  upon default by an  issuer of a portfolio  security, the Money Market
Series would first offset the negative  amount with respect to each  shareholder
account  from the dividends declared during the  month with respect to each such
account. If and to  the extent that such  negative amount exceeds such  declared
dividends at the end of the month (or during the month in the case of an account
liquidated  in its entirety), the Money Market Series could reduce the number of
its outstanding shares by treating each  shareholder of the Money Market  Series
as  having contributed to its capital that  number of full and fractional shares
of the Money Market Series in  the account of such shareholder which  represents
its  proportion of such excess. Each shareholder the Money Market Series will be
deemed to  have  agreed to  such  contribution  in these  circumstances  by  its
investment in the Money Market Series. This procedure would permit the net asset
value  per share of the Money Market Series to be maintained at a constant $1.00
per share.

ALL OTHER SERIES:  Each Series  other than the  Money Market  Series intends  to
distribute  to its shareholders annually dividends substantially equal to all of
its net  investment  income. Such  Series'  net investment  income  consists  of
non-capital  gain income  less expenses. Such  Series' intend  to distribute net
realized short-  and  long-term  capital  gains,  if  any,  at  least  annually.
Shareholders  will be  informed of the  tax consequences  of such distributions,
including whether any portion represents a  return of capital, after the end  of
each  calendar  year. (For  additional  taxation information,  see  "Tax Status"
above.)

8.  DETERMINATION OF NET ASSET VALUE;
   PERFORMANCE INFORMATION

NET ASSET VALUE

The net asset value per share of each Series is determined each day during which
the Exchange is open  for trading. This determination  is made once during  each
such  day as of  the close of regular  trading on the  Exchange by deducting the
amount of a Series' liabilities  from the value of  its assets and dividing  the
difference by the number of shares of the Series outstanding.

MONEY  MARKET SERIES: Portfolio securities of the Money Market Series are valued
at amortized cost, which the Trustees have determined in good faith  constitutes
fair  value for  the purposes  of complying  with the  1940 Act.  This valuation
method will continue to be used until  such time as the Trustees determine  that
it  does not constitute  fair value for  such purposes. The  Money Market Series
will limit  its  portfolio  to  those  investments  in  U.S.  dollar-denominated
instruments which the Board of Trustees determines present minimal credit risks,
and  which are of high qualify as determined  by any major rating service or, in
the case  of any  instrument that  is not  so rated,  of comparable  quality  as
determined  by the Board of Trustees. The Money Market Series has also agreed to
maintain a dollar-weighted  average maturity of  90 days or  less and to  invest
only  in securities  maturing in 13  months or  less. The Board  of Trustees has
established procedures designed to  stabilize the net asset  value per share  of
the  Money Market Series, as computed for the purposes of sales and redemptions,
at $1.00 per share. If  the Trustees determine that  a deviation from the  $1.00
per  share price  may exist  which may  result in  a material  dilution or other
unfair result to investors or  existing shareholders, they will take  corrective
action  as they regard as necessary  and appropriate, which action could include
the sale of instruments prior to maturity (to realize capital gains or  losses);
shortening  average portfolio  maturity; withholding dividends;  or using market
quotations for valuation purposes.

ALL OTHER  SERIES:  Securities,  futures  contracts and  options  in  a  Series'
portfolio  (other than short-term obligations) for which the principal market is
one or  more securities  or commodities  exchanges 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.  Debt securities  (other  than
short-term  obligations but including listed issues)  in a Series' 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  institutional-sized trading  in
similar  groups of securities,  yields, quality, coupon  rate, maturity, type of
issue, trading characteristics and other market data, without exclusive reliance
upon quoted prices or exchange or over-the-counter prices, since such valuations
are believed  to reflect  more accurately  the fair  value of  such  securities.
Short-term

                                       22
<PAGE>
obligations,  if any, in a Series' portfolio are valued at amortized cost, which
constitutes fair  value  as determined  by  the Board  of  Trustees.  Short-term
securities  with a remaining maturity in excess  of 60 days will be valued based
upon dealer  supplied  valuations.  Portfolio  securities  and  over-the-counter
options,  for which  there are  no quotations or  valuations are  valued at fair
value as  determined in  good faith  by  or at  the direction  of the  Board  of
Trustees.

PERFORMANCE INFORMATION

MONEY MARKET SERIES: The Money Market Series will provide current annualized and
effective  annualized yield quotations based on the daily dividends of shares of
the Money Market  Series. These  quotations may  from time  to time  be used  in
advertisements, shareholder reports or other communications to shareholders.

Any  current yield quotation of the Money Market  Series which is used in such a
manner as to  be subject to  the provisions of  Rule 482(d) under  the 1933  Act
shall consist of an annualized historical yield, carried at least to the nearest
hundredth  of one  percent, based  on a specific  seven calendar  day period and
shall be calculated by dividing the net change in the value of an account having
a balance of one share of that class at the beginning of the period by the value
of the account at the  beginning of the period  and multiplying the quotient  by
365/7.  For this purpose the net change in account value would reflect the value
of additional shares purchased with dividends declared on the original share and
dividends declared on both  the original share and  any such additional  shares,
but  would not reflect any realized gains  or losses from the sale of securities
or any  unrealized  appreciation or  depreciation  on portfolio  securities.  In
addition, any effective yield quotation of the Money Market Series so used shall
be  calculated by  compounding the  current yield  quotation for  such period by
multiplying such quotation by 7/365, adding 1 to the product, raising the sum to
a power  equal  to  365/7,  and  subtracting 1  from  the  result.  These  yield
quotations  should not be considered as representative of the yield of the Money
Market Series in the future since the yield will vary based on the type, quality
and maturities  of  the  securities  held  in  its  portfolio,  fluctuations  in
short-term interest rates and changes in the Money Market Series expenses.

ALL OTHER SERIES:

TOTAL  RATE OF RETURN --  Each Series, other than  the Money Market Series, will
calculate its  total  rate  of return  of  its  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)  to reach the  value of that  investment at the  end of the periods.
Each Series may also calculate total  rates of return which represent  aggregate
performance  over a  period or  year-by-year performance.  The aggregate average
annual total rate of return for shares  of the World Governments Series for  the
period  from June 10, 1994 (commencement of operations) to December 31, 1994 was
0.79% (including the effect of the  sales charge) and 0.79% (without the  effect
of the sales charge).

YIELD  -- Any yield quotation for a  Series, other than the Money Market Series,
is based on the annualized  net investment income per  share of that Series  for
the 30-day period. The yield for such a Series is calculated by dividing its net
investment  income earned during the  period by the offering  price per share of
that Series  on  the last  day  of the  period.  The resulting  figure  is  then
annualized.  Net investment income  per share is determined  by dividing (i) the
dividends and interest of that Series during the period, minus accrued  expenses
of  that Series  for the  period by (ii)  the average  number of  shares of that
Series entitled  to  receive  dividends  during the  period  multiplied  by  the
offering  price per share on  the last day of  the period. The yield calculation
for shares of the World Governments Series for the 30-day period ended  December
31, 1994 was 7.46% taking into account certain fee waivers.

CURRENT  DISTRIBUTION RATE -- Yield, which  is calculated according to a formula
prescribed by the Securities and Exchange  Commission, is not indicative of  the
amounts  which were or will be paid  to the Fund's 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
current  distribution rate for shares of the World Governments Series for the 12
month period ended December 31, 1994 was 2.65%.

From time  to time  each Series  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,
Morningstar,  Lipper Analytical  Services, Inc., Variable  Annuity Research Data
Service, CDA Wiesenberger, Shearson Lehman and Salomon Bros. Indices,  Ibbotson,
Business Week, Lowry Associates, Media General, Investment Company Data, The New
York Times, Your 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.  Series' performance  may also  be compared  to the  performance of  other
mutual funds tracked by financial or business publications or periodicals.

The  Series  may  also  quote  evaluations  mentioned  in  independent  radio or
television broadcasts.

From time to time the  Series may use charts and  graphs to illustrate the  past
performance of various indices such as those mentioned above.

9.  DESCRIPTION OF SHARES, VOTING RIGHTS AND LIABILITIES

The  Trust's Declaration of Trust permits the  Trustees of the Trust 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  the twelve series identified  on page 2 hereof.
The Declaration  of  Trust  further  authorizes  the  Trustees  to  classify  or
reclassify  any series of shares into one  or more classes. The Trustees have no
current intention to classify  more than one  class of shares.  Each share of  a
Series  represents an equal proportionate interest  in the assets of the Series.
Upon liquidation of a Series, shareholders  of the Series are entitled to  share
PRO  RATA  in  the  net  assets of  the  Series  available  for  distribution to
shareholders. The Trust reserves the right to create and issue additional series
or classes of shares, in which case  the shares of each class 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, shareholders
have under certain  circumstances the right  to remove one  or more Trustees  in
accordance  with the provisions  of Section 16(c)  of the 1940  Act. No material
amendment may be made to the  Declaration of Trust without the affirmative  vote
of  a majority of the  Trust's shares. Shares have  no pre-emptive or conversion
rights. Shares are  fully paid and  non-assessable. The Trust  may enter into  a
merger  or consolidation, or sell 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 outstanding
shares voting as a single class, or of the affected series of the Trust, as  the
case  may be, except  that if the  Trustees of the  Trust 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  (as defined in "Investment
Restrictions") will be sufficient. The Trust or any series of the Trust may also
be terminated (i) upon liquidation and  distribution of its assets, if  approved
by  the vote of the holders of two-thirds  of its outstanding shares, or (ii) by
the Trustees by written notice to the shareholders of the Trust of the  affected
series. 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  it  shall  maintain  appropriate  insurance  (for example,
fidelity bonding and errors and omissions  insurance) for the protection of  the
Trust,  its  shareholders,  Trustees, officers,  employees  and  agents covering
possible tort or 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

                                       24
<PAGE>
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 willful misfeasance, bad  faith, gross negligence,  or reckless disregard  of
the duties involved in the conduct of his office.

NOTES:

(1) The MFS Variable Insurance Trust (the "Trust") was organized on February  1,
    1994   as  a  business   trust  under  the  laws   of  The  Commonwealth  of
    Massachusetts. The Trust currently  consists of twelve  series of shares  or
    funds  (the "Series"):  MFS Emerging Growth  Series, MFS  Growth Series, MFS
    Research Series, MFS Growth with Income Series, MFS Total Return Series, MFS
    Utilities Series, MFS High Income Series, MFS World Governments Series,  MFS
    Strategic  Fixed Income Series, MFS Bond Series, MFS Limited Maturity Series
    and MFS Money Market Series. Each  Series, except for the World  Governments
    Series, has been inactive since that date except for matters relating to its
    organization and the Trust's registration as an investment company under the
    Investment  Company Act  of 1940  and the sale  of 860  shares of beneficial
    interest (except  the  MFS Money  Market  Series)  and of  8,600  shares  of
    beneficial interest of the MFS Money Market Series (the "initial shares") to
    Massachusetts Financial Services Company.
(2)  Organization expenses  are being deferred  and will be  amortized over five
    years beginning with the commencement  of investment operations. The  amount
    paid  by any  Series on any  redemption by  Massachusetts Financial Services
    Company, or  any current  holder  of any  Series'  initial shares,  will  be
    reduced  by the  pro rata portion  of any  unamortized organization expenses
    which the number  of initial shares  redeemed bears to  the total number  of
    initial shares outstanding immediately prior to such redemption.

                          INDEPENDENT AUDITORS' REPORT

To the Board of Trustees of MFS Variable Insurance Trust and Shareholders of MFS
OTC Series, MFS Growth Series, MFS Research Series, MFS Growth with Income
Series, MFS Total Return Series, MFS Utilities Series, MFS High Income Series,
MFS World Governments Series, MFS Strategic Fixed Income Series, MFS Bond
Series, MFS Limited Maturity Series, MFS Money Market Series:

We have audited the accompanying statements of assets and liabilities of MFS OTC
Series,  MFS Growth Series, MFS Research  Series, MFS Growth with Income Series,
MFS Total Return Series, MFS Utilities Series, MFS High Income Series, MFS World
Governments Series,  MFS Strategic  Fixed Income  Series, MFS  Bond Series,  MFS
Limited Maturity Series, MFS Money Market Series, (the "Series") (comprising the
MFS  Variable  Insurance Trust  (the "Trust"))  as of  December 31,  1994. These
financial statements  are  the responsibility  of  the Trust's  management.  Our
responsibility  is to express an opinion  on these financial statements based on
our audits.

We  conducted  our  audits  in  accordance  with  generally  accepted   auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the  statements of assets and liabilities  is
free  of material  misstatement. An audit  includes examining, on  a test basis,
evidence supporting the amounts and disclosures  in the statement of assets  and
liabilities. 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 of the  statements
of assets and liabilities provide a reasonable basis for our opinion.

In our opinion, such statements of assets and liabilities present fairly, in all
material  respects, the financial position of each of the Series at December 31,
1994 in conformity with generally accepted accounting principles.

ITEM 27.  INDEMNIFICATION

          Section 5.3 of the Registrant's Declaration of Trust (filed with
Registrant's Registration Statement on February 1, 1994) provides that every
person who is or has been a Trustee or officer of the Registrant shall be
indemnified by the Registrant against all liability and against all expenses
reasonably incurred or paid by him in connection with any claim, action, suit or
proceeding in which he becomes involved as a party or otherwise by virtue of his
being or



<PAGE>




having been a Trustee or officer and against amounts paid or incurred by him in
the settlement thereof.  However, Section 5.3 further provides that no
indemnification shall be provided to a Trustee or officer:

          (i)   against any liability to the Registrant or the shareholders of
the Registrant by reason of a final adjudication by the court or other body
before which the proceeding was brought that he engaged in willful misfeasance,
bad faith, gross negligence or reckless disregard of the duties involved in the
conduct of his office;

          (ii)  with respect to any matter as to which he shall have been
finally adjudicated not to have acted in good faith in the reasonable belief
that his action was in the best interest of the Registrant; or

          (iii) in the event of a settlement involving a payment by a Trustee
or officer or other disposition not involving a final adjudication as provided
in paragraph (i) or (ii) above resulting in a payment by a Trustee or officer,
unless there has been either a determination that such Trustee or officer did
not engage in willful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in the conduct of his office by the court or
other body approving the settlement or other disposition or by a reasonable
determination, based upon a review of readily available facts (as opposed to a
full trial-type inquiry) that he did not engage in such conduct:

          (A)   by vote of a majority of the Disinterested Trustees (as defined
below) acting on the matter (provided that a majority of the Disinterested
Trustees then in office act on the matter); or

          (B)   by written opinion of independent legal counsel.

          The term "Disinterested Trustee" is defined as one who is not an
interested person of the Registrant and against whom none of such actions, suits
or other proceedings or another action, suit or other proceeding on the same or
similar grounds is then or had been pending.

          Expenses of preparation and presentation of a defense to any claim,
action, suit, or proceeding of the character described in Section 5.3 of the
Registrant's Declaration of Trust shall be advanced by the Registrant prior to
final disposition thereof upon receipt of an undertaking by or on behalf of the
recipient to repay such amount if it is ultimately determined that he is not
entitled to indemnification under Section 5.3, provided that either:

          (i)   such undertaking is secured by a surety bond or some other
appropriate security or the Registrant shall be insured against losses arising
out of any such advances; or

          (ii)  a majority of the Disinterested Trustees acting on the matter
(provided that a majority of the Disinterested Trustees then in office act on
the matter) or an independent legal counsel in a written opinion, shall
determine, based upon a review of readily available facts (as opposed to a full
trial-type inquiry), that there is reason to believe that the recipient
ultimately will be found entitled to indemnification.



<PAGE>

   

          Section 9 of the form of Shareholder Servicing Agent Agreement between
the Registrant and MFS Service Center, Inc. ("MFSC"), which was filed with the
Securities and Exchange Commission on October 20, 1994, specifies that the
Registrant will indemnify MFSC against and hold MFSC harmless from any and all
losses, claims, damages, liabilities or expenses (including reasonable counsel
fees and expenses) resulting from any claim, demand, action or suit not
resulting from MFSC's bad faith or negligence, and arising out of, or in
connection with, MFSC's duties on behalf of the Registrant under such Agreement.
In addition, Section 9 provides that the Registrant will indemnify MFSC against
and hold MFSC harmless from any and all losses, claims, damages, liabilities or
expenses (including reasonable counsel fees and expenses) resulting from any
claim, demand, action or suit as a result of MFSC acting in accordance with any
instructions reasonably believed by MFSC to have been executed or orally
communicated by any person duly authorized by the Registrant or its principal
underwriter, or as a result of acting in accordance with written or oral advice
reasonably believed by MFSC to have been given by counsel for the Registrant, or
as a result of acting in accordance with any instrument or share certificate
reasonably believed by MFSC to have been genuine and signed, countersigned or
executed by any person or persons authorized to sign, countersign or execute the
same (unless contributed to by MFSC's gross negligence or bad faith).
    

          The Trustees and officers of the Registrant and the personnel of the
Registrant's investment adviser and distributor will be insured as of the
effective date of this Registration Statement under an errors and omissions
liability insurance policy.  The Registrant and its officers are also insured
under the fidelity bond required by Rule 17g-1 under the Investment Company Act
of 1940, as amended.

ITEM 31.  MANAGEMENT SERVICES

           Not applicable.

ITEM 32.  UNDERTAKINGS

          (a)  Not applicable.

          (b)  Not applicable.

          (c)  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, 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.

          (d)  The registrant undertakes to furnish each person to whom a
prospectus is delivered with a copy of the Registrant's latest annual report to
shareholders upon request and without charge.
