MFS Variable Insurance Trust (the "Trust") is an open-end management investment
company offering insurance company separate accounts a selection of investment
vehicles for variable annuity and variable life insurance contracts (the
"Contracts"). Currently the Trust offers shares of beneficial interest of 12
separate mutual fund series (individually or collectively hereinafter referred
to as a "Series" or the "Series"), one of which is offered pursuant to this
Prospectus.
- -- MFS VALUE SERIES (the "Value Series"), which seeks capital appreciation.
-------------------
THE VALUE SERIES IS INTENDED FOR INVESTORS WHO UNDERSTAND AND ARE WILLING TO
ACCEPT THE RISKS
ENTAILED IN SEEKING LONG-TERM GROWTH OF CAPITAL. BECAUSE OF ITS INVESTMENT
POLICIES PERMITTING INVESTMENT IN FOREIGN SECURITIES, INVESTMENTS IN THE 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
PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY
REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
-------------------
SHARES OF THE TRUST ARE AVAILABLE AND ARE BEING MARKETED AS A POOLED FUNDING
VEHICLE FOR LIFE INSURANCE COMPANIES WRITING ALL TYPES OF CONTRACTS.
This Prospectus sets forth concisely the information about the Series that a
prospective investor should know before applying for the Contracts offered by

- ------------------------
(1) The Adviser has agreed to bear, subject to reimbursement, expenses for the Value Series such that the 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 from
January 1, 1999 through December 31, 2004; provided however, that this obligation may be terminated or revised at
any time. See "Information Concerning Shares of Each Series--Expenses" below. Absent this expense arrangement,
"Other Expenses" and "Total Operating Expenses" would be 1.00% and 1.75%, respectively for the Value Series.
(2) The Series has an expense offset arrangement which reduces the Series' custodian fee based upon the amount of
cash maintained by the Series with its custodian and dividend disbursing agent, and may enter into other such
arrangements and directed brokerage arrangements (which would also have the effect of reducing the Series'
expenses). Any such fee reductions are not reflected under "Other Expenses."
</TABLE>
The purpose of the expense table above is to assist investors in
understanding the various costs and expenses that a shareholder of the Series
will bear directly or indirectly. 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, Value 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 offers 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
3
<PAGE>
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 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.
3. CONDENSED FINANCIAL INFORMATION
The Series' current independent auditors are Deloitte & Touche LLP. The
Value Series had not commenced investment operations prior to December 31, 1995.
4. INVESTMENT OBJECTIVES AND POLICIES
The investment objectives and policies of the 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 the Series will be achieved.
In addition to the specific investment practices described below, the Series
may also engage in certain investment techniques as described under the caption
"Investment Techniques" below and in the SAI under the caption "Investment
Techniques." The Series' investments are subject to certain risks, as described
in the above-referenced sections of this Prospectus and the SAI and as described
below under the caption "Additional Risk Factors."
MFS VALUE SERIES -- The Value Series' investment objective is to seek capital
appreciation. Dividend income, if any, is a consideration incidental to the
Series' objective of capital appreciation.
While the Series' policy is to invest primarily in common stocks, it may
seek appreciation in other types of securities such as fixed income securities
(which may be unrated), convertible bonds, convertible preferred stocks and
warrants when relative values make such purchases appear attractive either as
individual issues or as types of securities in certain economic environments.
The Series may invest in fixed income securities rated lower than "investment
grade" (rated Ba or lower by Moody's Investors Service, Inc. ("Moody's") or BB
or lower by Standard & Poor's Ratings Services ("S&P") or Fitch Investors
Service, Inc. ("Fitch")) (commonly known as "junk bonds") or in comparable
unrated securities, when, in the opinion of the Adviser, such an investment
presents a greater opportunity for appreciation with comparable risk to an
investment in "investment grade" securities. Under normal market conditions, the
Series will invest not more than 25% of its net assets in these securities. For
a description of these ratings, see Appendix A to this Prospectus.
Consistent with its investment objective and policies described above, the
Series may also invest up to 50% (and generally expects to invest not more than
25%) of its net assets in foreign securities (including emerging market
securities and Brady Bonds) which are not traded on a U.S. exchange. There is no
formula as to the percentage of assets that may be invested in any one type of
security. Cash, commercial paper, short-term obligations, repurchase agreements
or debt securities are held to provide for future purchases of common stock or
other securities and may also be held as a temporary defensive measure when the
Adviser determines security markets to be overvalued.

<PAGE>
5. INVESTMENT TECHNIQUES
LENDING OF PORTFOLIO SECURITIES: The 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, U.S. Treasury securities or an
irrevocable letter of credit 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 10% of the value of the net assets of the Series making the
loans.
EMERGING MARKET SECURITIES: Consistent with its respective objectives, the
Series may invest in securities of issuers whose principal activities are
located in emerging market countries. Emerging market countries include any
country determined by the Adviser to have an emerging market economy, taking
into account a number of factors, including whether the country has a low- to
middle- income economy according to the International Bank for Reconstruction
and Development, the country's foreign currency debt rating, its political and
economic stability and the development of its financial and capital markets. The
Adviser determines whether an issuer's principal activities are located in an
emerging market country by considering such factors as its country of
organization, the principal trading market for its securities and the source of
its revenues and assets. The issuer's principal activities generally are deemed
to be located in a particular country if: (a) the security is issued or
guaranteed by the government of that country or any of its agencies, authorities
or instrumentalities; (b) the issuer is organized under the laws of, and
maintains a principal office in that country; (c) the issuer has its principal
securities trading market in that country; (d) the issuer derives 50% or more of
its total revenues from goods sold or services performed in that country; or (e)
the issuer has 50% or more of its assets in that country.
BRADY BONDS: The Series may invest in Brady Bonds, which are securities
created through the exchange of existing commercial bank loans to public and
private entities in certain emerging markets for new bonds in connection with
debt restructurings under a debt restructuring plan introduced by former U.S.
Secretary of the Treasury, Nicholas F. Brady (the "Brady Plan"). Brady Plan debt
restructurings have been implemented to date in Argentina, Brazil, Bulgaria,
Costa Rica, Dominican Republic, Ecuador, Jordan, Mexico, Nigeria, Panama, the
Philippines, Poland, Uruguay and Venezuela. Brady Bonds have been issued only
recently, and for that reason do not have a long payment history. Brady Bonds
may be collateralized or uncollateralized, are issued in various currencies (but
primarily the U.S. dollar) and are actively traded in over-the-counter secondary
markets. U.S. dollar-denominated, collateralized Brady Bonds, which may be
fixed-rate bonds or floating-rate bonds, are generally collateralized in full as
to principal by U.S. Treasury zero coupon bonds having the same maturity as the
bonds. Brady Bonds are often viewed as having three or four valuation
components: the collateralized repayment of principal at final maturity; the
collateralized interest payments; the uncollateralized interest payments; and
any uncollateralized repayment of principal at maturity (these uncollateralized
amounts constituting the "residual risk"). In light of the residual risk of
Brady Bonds and the history of defaults of countries issuing Brady Bonds with
respect to commercial bank loans by public and private entities, investments in
Brady Bonds may be viewed as speculative.
REPURCHASE AGREEMENTS: The Series may enter into repurchase agreements in
order to earn 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 SAI, each Series has adopted certain procedures intended to
minimize risk.
"WHEN-ISSUED" SECURITIES: The 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
5
<PAGE>
security. In general, the 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, the Series will normally invest in cash, cash equivalents and high
grade debt securities.
RESTRICTED SECURITIES: The Series may purchase securities that are not
registered under the Securities Act of 1933 (the "1933 Act") ("restricted
securities"), including those that can be offered and sold to "qualified
institutional buyers" under Rule 144A under the 1933 Act ("Rule 144A
securities"). 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 liquid and thus not subject to the Series' limitation on investing
not more than 15% of its net assets in illiquid investments. 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 the 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 decreasing the level of liquidity in the Series to the extent that
qualified institutional buyers become for a time uninterested in purchasing Rule
144A securities held in the Series' portfolio.
ZERO COUPON BONDS, DEFERRED INTEREST BONDS AND PIK BONDS: The Series may
invest in zero coupon bonds, and 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.
The 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.
LOAN PARTICIPATIONS AND OTHER DIRECT INDEBTEDNESS: The Series may invest a
portion of its assets in "loan participations" and other direct indebtedness. By
purchasing a loan participation, the 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. The 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 the 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.
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,
the 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 SAI.
6
<PAGE>
INDEXED SECURITIES: The 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 (I.E., principal value) and/or
interest rates rise or fall according to the change in one or more specified
underlying instruments. Indexed securities may be positively or negatively
indexed (I.E., their principal value or interest rates may increase or decrease
if the underlying instrument appreciates), and may have return characteristics
similar to direct investments in the underlying instrument or to one or more
options on the underlying instrument. Indexed securities may be more volatile
than the underlying instrument itself.
OPTIONS ON SECURITIES: The Series may write (sell) covered put and call
options and purchase put and call options on securities. The 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 the 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. The 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, the 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.
The 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.
OPTIONS ON STOCK INDICES: The Series may write (sell) covered call and put
options and purchase call and put options on stock indices. The 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 the 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. The 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 the Series for the writing of the option, less related
transaction costs. In addition, if the value of an underlying index moves
adversely to the 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.
The 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. The Series'
possible loss in either case will be limited to the premium paid for the option,
plus related transaction costs.
"YIELD CURVE" OPTIONS: The 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
7
<PAGE>
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 the
Series will be covered as described in the SAI. 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 SAI. 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: The Series may purchase
and sell Futures Contracts on stock indices and may purchase and sell Futures
Contracts on foreign currencies or indices of foreign currencies. The 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. The 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 benefit the
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. The Series will not enter into any Futures Contract if immediately
thereafter the value of securities and other obligations underlying all such
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
the 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
the Series will be traded on U.S. and foreign exchanges.
FORWARD CONTRACTS: The 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"). The Series may enter into
Forward Contracts for hedging purposes and for non-hedging purposes (I.E.,
speculative purposes). By entering into transactions in Forward Contracts for
hedging purposes, the 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, the 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. The 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 Series may hold such currencies for an indefinite period of time.
The 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. The Series has established procedures consistent with
statements of the SEC and its staff regarding the use of Forward Contracts by
registered investment companies, which requires use of segregated assets or
"cover" in connection with the purchase and sale of such contracts.
8
<PAGE>
OPTIONS ON FOREIGN CURRENCIES: The Series may 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 the 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 the Series' position, it may forfeit the entire amount of the premium paid
for the option plus related transaction costs. The Series may also choose to, or
be required to, receive delivery of the foreign currencies underlying Options on
Foreign 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, the Series may hold such currencies
for an indefinite period of time.
6. ADDITIONAL RISK FACTORS
OPTIONS, FUTURES CONTRACTS AND FORWARD CONTRACTS: Although the 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 the
Series' hedging strategy unsuccessful and could result in losses. The 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
the 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 the Series
may be required to maintain a position until exercise or expiration, which could
result in losses. The SAI contains a description of the nature and trading
mechanics of options, 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: The Series may invest in fixed income 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.
The 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. See Appendix A to this Prospectus
for a description of these ratings. 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
9
<PAGE>
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 the 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, the 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 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 SAI for more information on lower rated securities.
FOREIGN SECURITIES: The 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 U.S. 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. The 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. The Series may also hold
foreign currency in anticipation of purchasing foreign securities. See the SAI
for further discussion of foreign securities and the holding of foreign
currency, as well as the associated risks.
AMERICAN DEPOSITARY RECEIPTS: 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. Because ADRs trade on U.S. 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.
EMERGING MARKET SECURITIES: The 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 in losses to the Series due to subsequent declines in value of the
portfolio securities, a decrease in the level of liquidity in the Series'
portfolio, 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, and in such markets the Series bears the risk that
the securities will not be delivered and that the Series' payments will not be
returned. Securities prices in emerging markets can be significantly more
volatile
10
<PAGE>
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 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 a Series.
-------------------
SHORT-TERM INVESTMENTS FOR TEMPORARY DEFENSIVE PURPOSES -- During periods of
unusual market conditions when the Adviser believes that investing for temporary
defensive purposes is appropriate, or in order to meet anticipated redemption
requests, a large portion or all of the assets of the 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.
PORTFOLIO TRADING
The 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.
The 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, the 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 SAI.
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 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
SAI.
-------------------
11
<PAGE>
The SAI includes a discussion of other investment policies and listing of
specific investment restrictions which govern the investment policies of the
Series. The specific investment restrictions listed in the SAI may be changed
without shareholder approval unless indicated otherwise (see the SAI). 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 the Series'
day-to-day management.
INVESTMENT ADVISER -- MFS manages the Series pursuant to an Investment Advisory
Agreement with the Trust on behalf of the 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
the 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:

Value Series John F. Brennan, Jr., a Senior Vice President of MFS, has been employed by the
Adviser as a portfolio manager since 1985.
</TABLE>
MFS also serves as investment adviser to each of the other funds in the MFS
Family of Funds (the "MFS Funds") and to MFS-Registered Trademark- Municipal
Income Trust, MFS Multimarket Income Trust, MFS Government Markets Income Trust,
MFS Intermediate Income Trust, MFS Charter Income Trust, MFS Special Value
Trust, MFS Institutional Trust, MFS Union Standard Trust, MFS/Sun Life Series
Trust, Sun Growth Variable Annuity Fund, Inc. and seven variable accounts, each
of which is a registered investment company established by Sun Life Assurance
Company of Canada (U.S.) ("Sun Life of Canada (U.S.)") in connection with the
sale of various fixed/variable annuity contracts. MFS and its wholly owned
subsidiary, MFS 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 $45.7 billion on behalf of approximately 2.0 million investor
accounts as of April 30, 1996. As of such date, the MFS organization managed
approximately $21.9 billion of assets invested in equity securities and
approximately $19.4 billion of assets invested in fixed income securities.
Approximately $3.8 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
wholly owned 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.
12
<PAGE>
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.
MFS has established a strategic alliance with Foreign & Colonial Management
Ltd. ("Foreign & Colonial"). Foreign & Colonial is a subsidiary of two of the
world's oldest financial services institutions, the London-based Foreign &
Colonial Investment Trust PLC, which pioneered the idea of investment management
in 1868, and HYPO-BANK (Bayerische Hypotheken-und Weschsel-Bank AG), the oldest
publicly listed bank in Germany, founded in 1835. As part of this alliance, the
portfolio managers and investment analysts of MFS and Foreign & Colonial will
share their views on a variety of investment related issues, such as the
economy, securities markets, portfolio securities and their issuers, investment
recommendations, strategies and techniques, risk analysis, trading strategies
and other portfolio management matters. MFS will have access to the extensive
international equity investment expertise of Foreign & Colonial, and Foreign &
Colonial will have access to the extensive U.S. equity investment expertise of
MFS. One or more MFS investment analysts are expected to work for an extended
period with Foreign & Colonial's portfolio managers and investment analysts at
their offices in London. In return, one or more Foreign & Colonial employees are
expected to work in a similar manner at MFS' Boston offices.
In certain instances there may be securities which are suitable for the
Series' portfolio as well as for portfolios of other clients of MFS or clients
of Foreign & Colonial. Some simultaneous transactions are inevitable when
several clients receive investment advice from MFS and Foreign & Colonial,
particularly when the same security is suitable for more than one client. While
in some cases this arrangement could have a detrimental effect on the price or
availability of the security as far as the Series is concerned, in other cases,
it may produce increased investment opportunities for the Series.
From time to time, the Adviser may purchase, redeem and exchange shares of
the Series. The purchase by the Adviser of shares of the Series may have the
effect of lowering that Series' expense ratio, while the redemption by the
Adviser of shares of the 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 THE SERIES
PURCHASES AND REDEMPTIONS
The separate accounts of the Participating Insurance Companies place orders
to purchase and redeem shares of the 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.
13
<PAGE>
The offering of shares of the Series may be suspended for a period of time
and the 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 the Series. The Trust may suspend the right
of redemption of shares of the 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 the Series, orderly
portfolio management could be disrupted to the potential detriment of such
Contract.
NET ASSET VALUE
The net asset value per share of the 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 the Series' portfolio are determined on the basis of their
market or other fair value, as described in the SAI. All investments, assets and
liabilities are expressed in U.S. dollars based upon current currency exchange
rates.
DISTRIBUTIONS
Substantially all of the 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, the 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, the
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 the Series' investment restrictions, premiums from
options written), over a longer term, rather than its actual net investment
income for the period.
Shareholders of the Series may elect to receive dividends and capital gain
distributions in either cash or additional shares.
TAX STATUS
The Series of the Trust is treated as a separate entity for federal income
tax purposes. In order to minimize the taxes the Series would otherwise be
required to pay, the 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 SAI.
DESCRIPTION OF SHARES, VOTING RIGHTS AND LIABILITIES
The 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 the 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 the Series are entitled
to vote separately to approve investment advisory agreements or changes in
investment restrictions with respect to the Series, but shares of the Series
14
<PAGE>
vote together in the election of Trustees and selection of accountants.
Additionally, the 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 SAI.
Each share of the 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.
PERFORMANCE INFORMATION
The Series' performance may be quoted in advertising in terms of yield and
total return. Performance is based on historical results and is not intended to
indicate future performance. Performance quoted for the 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 the Series will vary based on, among
other things, changes in market conditions, the level of interest rates and the
level of the Series' expenses.
From time to time, quotations of the Series' total return and yield may be
included in advertisements, sales literature or reports to shareholders or
prospective investors. The total return of the 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 the 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 the 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 the 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 the Series; expenses of repurchasing and redeeming
shares and servicing shareholder accounts; expenses of preparing, printing and
mailing prospectuses, periodic reports, notices and proxy statements to
shareholders and to governmental officers and commissions; brokerage and other
expenses connected with the execution, recording and settlement of portfolio
security transactions; insurance premiums; fees and expenses of Investors Bank &
Trust Company, the Trust's Custodian, for all services to the Series, including
safekeeping of funds and securities and maintaining required books and accounts;
expenses of calculating the net asset value of shares of the Series; and
expenses of shareholder meetings. Expenses relating to the issuance,
registration and qualification of shares of the Series and the preparation,
printing and mailing of prospectuses are borne by the Series
15
<PAGE>
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 the Series are allocated between the Series in a
manner believed by management of the Trust to be fair and equitable.
MFS has agreed to pay expenses of the Series such that the 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 from January 1, 1999 through December
31, 2004; 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
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 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 from January 1, 1999 through December
31, 2004. This expense reimbursement agreement terminates for each the Series on
the earlier of the date on which payments made thereafter by the Series equal
the prior payment of such reimbursable expenses by MFS or December 31, 2004.
SHAREHOLDER COMMUNICATIONS
Owners of Contracts issued by Participating Insurance Companies for which
shares of one or more Series are the investment vehicle will receive from the
Participating Insurance Companies semi-annual financial statements and audited
year-end financial statements certified by the Trust's independent certified
public accountants. Each report will show the investments owned by the Trust and
the valuations thereof as determined by the Trustees and will provide other
information about the Trust and its operations.
Participating Insurance Companies with inquiries regarding the Trust may
call the Trust's Shareholder Servicing Agent. (See back cover for address and
phone number.)

APPENDIX A
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;
A-1
<PAGE>
3. there is a lack of essential data pertaining to the issue or issuer; or
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 SERVICES
AAA: Debt rated AAA has the highest rating assigned by S&P. Capacity to pay
interest and repay principal is extremely strong.
AA: Debt rated AA has a very strong capacity to pay interest and repay
principal and differs from the highest 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.
CI: The rating CI is reserved for income bonds on which no interest is being
paid.
D: Debt rated D is in payment default. The D rating category is used when
interest payments or principal payments are not made on the date due, even if
the applicable grace period has not expired, unless S&P believes that such
payments will be made during such grace period. The D rating also will be used
upon the filing of a bankruptcy petition if debt service payments are
jeopardized.

PLUS (+) OR MINUS (-): The ratings from AA to CCC may be modified by the
addition of a plus or minus sign to show relative standing within the major
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.
A-1 AND P-1 COMMERCIAL PAPER RATINGS
Description of S&P, Fitch and Moody's highest commercial paper ratings:
The rating "A" is the highest commercial paper rating assigned by S&P and
Fitch, 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.
A-3
<PAGE>
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.
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.

AA: Bonds considered to be investment grade and or very high credit quality.
The obligor's ability to pay interest and repay principal is very strong,

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