MFS Mourns Chairman's Passing

It is with deep regret that we inform you of the death on February 2, 1998, of
A. Keith Brodkin, Chairman and Chief Executive Officer of MFS Investment
ManagementSM. Mr. Brodkin joined MFS in 1970 and made enormous contributions to
the organization, including helping to build the firm's investment staff, which
will continue to manage all of the MFS investment portfolios. His leadership,
friendship, and wise counsel will be sorely missed.

Dear Contract Owners:

Thanks to a sustained period of relative stability and moderate growth, the U.S.
economy has produced thousands of new jobs, inflation has remained under
control, and the investment climate has -- for the most part -- been favorable.
The increased use of technology and other productivity enhancements, as well as
corporate restructuring and global competition, is improving companies' balance
sheets and helping control inflation. The rapid pace of growth seen in the first
quarter slowed to an annual rate of 3.3% in the second quarter and 3.5% in the
third. We believe this economic momentum will carry well into the first quarter
of 1998, as long-term interest rates have declined and the money supply is
increasing at a rapid rate. While economic growth in the United States continues
to be impressive, this is being partially offset by events in the Pacific Rim.
Thus, markets will most likely continue to focus on activity by the Federal
Reserve Board (the Fed) and its response to both U.S. and world events.

Global Outlook

The second half of 1997 brought turmoil to the world's investment markets as
concerns about Asia mounted and as liquidity, which has been high for the past
few years, began to dry up. While markets in Europe, the United States, and even
Latin America performed reasonably well, the cumulative effect of large
current-account deficits, followed by the collapse of several large financial
institutions and corporations, created a situation in Asia that could remain
unstable for some time. Although the Asian crisis affected other emerging
markets, valuations in several of them have become more attractive, and we
believe the long-term case for emerging markets remains intact. In Europe, the
uncertainty over economic union appears to have diminished somewhat. Growth has
begun accelerating on the continent and may exceed U.S. growth in 1998.

Bond Markets

The U.S. government bond market has benefited from the deflationary events in
Asia, while the high-yield and emerging-debt markets have come under severe
pressure. Inflation remains under control, and the Fed will most likely take a
wait-and-see attitude toward raising interest rates. As a result, our near-term
outlook for high-grade markets is neutral to moderately positive. At the same
time, high-yield markets, having gone through a substantial correction, could
offer reasonable value but require careful selection. Overall, fixed-income
markets appear to be reasonably valued.

Stock Market

The extreme volatility seen in the U.S. equity market this fall was, we believe,
the consequence of overvaluations that had been evident for some months. As a
result, the stock market has been vulnerable to some type of correction and has
been impacted in the near term by chaotic market conditions in emerging markets
and the Pacific Rim. In the face of all this, however, the equity market
continues to exhibit surprising strength, much of it the result of continued
gains in corporate earnings, a trend that could be an important indicator of the
market's future direction. Certainly the situation throughout Asia bears close
scrutiny because it appears to be clearly deflationary and raises the prospect
of trade wars developing throughout the area. We are not convinced that U.S.
markets have escaped totally from October's volatility. Thus, not only is the
near-term outlook for profits under question due to the Asian crisis, we also
believe equity valuations have risen to a point where a cautious investment
approach seems warranted, with a need for particular attention to be paid to the
effect of Pacific Rim volatility on the earnings of U.S. companies.

A discussion of the performance and current investment strategy for each of the
Series is presented here and on the following pages. The performance figures
provided in the discussion do not reflect the deduction of any separate account
charges. The results would have been lower had those charges been deducted. We
appreciate your support and welcome any questions or comments you may have.

On behalf of the Board of Trustees,

Government Securities Series

For the year ended December 31, 1997, the Series provided a total return of
8.72%. This compares to a 9.54% return for the Lehman Brothers
Government/Mortgage Index (the Lehman Index), an unmanaged index of U.S.
Treasury, government-agency, and mortgage-backed securities. The portfolio is
currently positioned for stable interest rates over the near term. We have
reduced both the Series' overweighting in mortgage-backed securities and
positions that anticipate a flatter yield curve. Yield-curve positioning could
present future opportunities as the market assesses U.S. growth and the degree
of global liquidity needs.

The portfolio duration (a measure of interest-rate sensitivity) is currently
4.2%, versus a duration of 4.3% for the Lehman Index. Cash positions are usually
low and are currently at 4%. The portfolio is 45% invested in U.S. Treasuries,
with a market weighting across the yield curve. The portfolio also contains an
15% government-agency allocation, which is mostly invested in intermediate-term,
government-agency debentures and Small Business Association loans.

The greatest change in the portfolio has been the reduction in the holdings of
U.S. agency mortgage-backed pass-through certificates. Last year, mortgages
outperformed duration-equivalent Treasuries by over 1%. This year, as rates have
declined, the possibility of an increase in mortgage prepayments will limit the
return potential of this sector. The Series currently has a 36% position in
mortgage-backed securities, with an emphasis on lower-coupon issues and issues
with shorter 15-year stated final maturities.

High Yield Series

For the year ended December 31, 1997, the Series provided a total return of
13.24%. This compares to a 12.76% return for the Lehman Brothers High Yield Bond
Index, an unmanaged index of publicly issued, noninvestment-grade debt. The
Series' largest weighting was in the telecommunications industry, which posted
the best returns in the high-yield market. In this industry, we have focused on
the bonds of competitive local exchange carriers

                                                                               1

<PAGE>

(CLECs), which offer an array of telephone services and compete primarily with
the Baby Bells for business customers. We favored this sector because we believe
deregulation provides CLECs with many growth opportunities. In addition, these
companies have experienced strong customer demand because their new fiber optic
networks offer reliable low-cost service. The Series also benefited from
consolidation in the telecommunications sector because some of its holdings,
including Brooks Fiber and Orion Network Systems, were acquired by
investment-grade companies.

Emerging-market corporate and sovereign bond prices have weakened in response to
the Asian currency crisis. The Series benefited from an underweighting in this
sector. In addition, we have reduced positions in domestic companies with
significant export exposure to Asia. While we will look for investment
opportunities in this area as bond prices decline, we do not expect this sector
to be a significant component of the portfolio.

Given the high-yield market's strength over the past year, the Series'
performance was hindered by its overweighted position in defensive industries
such as consumer products. Going forward, we will continue to favor
higher-quality companies and avoid more speculative situations, given our
outlook for slower economic growth resulting from Asia's economic problems.

The past year was a robust one for the high-yield market. High-yield bonds were
once again one of the best-performing fixed-income asset classes, and new
issuance hit a record $119 billion, surpassing the previous record by $47
billion. The domestic economy continues to exhibit sound fundamentals and,
therefore, we expect the high-yield market's healthy performance to carry
through into 1998. At year-end, for example, the yield on the Salomon Brothers
High-Yield Bond Index, an unmanaged index of noninvestment-grade corporate
bonds, was 9.20%, compared to 5.73% for U.S. Treasury notes of comparable
maturity. (Principal value and interest on Treasury securities are guaranteed by
the U.S. government if held to maturity.) We believe that this spread of 3.47%
more than compensates investors for the credit risks associated with high-yield
bonds. We are excited about the prospects for the high-yield market in 1998 and,
as always, our investment process will be committed to developing rewarding
ideas through rigorous credit research.

International Growth and Income Series
(formerly MFS(R)/International Growth and Income)

For the year ended December 31, 1997, the Series provided a total return of
6.53%. This compares to a 7.27% return for the unmanaged Lipper International
Funds Index (the Lipper International Funds Index is an unmanaged,
net-asset-value-weighted index of the largest qualifying mutual funds within its
respective investment objectives, and is adjusted for the reinvestment of
capital gain distributions and income dividends. It is not possible to invest
directly in an index.) and to a 0.53% return for a blend (70% and 30%,
respectively) of the Morgan Stanley Capital International (MSCI) Europe,
Australia, Far East (EAFE) Index and the J.P. Morgan Global Government Bond
Index (the Morgan Index). The MSCI EAFE Index is an unmanaged index of
international stocks, while the Morgan Index is an unmanaged index of bonds
issued by 13 countries, excluding the United States, with remaining maturities
of at least one year.

Significant changes occurred in the portfolio in the last six months of 1997.
First of all, the Series is now almost entirely invested in equities. Second,
the Series is much more concentrated, with the top five sectors now accounting
for about 59% of assets, nearly double the level of six months ago. Consumer
staples and utilities and communications constitute the largest sectors, with
14% and 13.6% of assets, respectively. They are followed by financial services
at 12.2%, energy at 10.1%, and retailing at 8.6%. The top 10 holdings now
account for 25% of assets, versus 13% six months ago. These tend to be large
companies with steady growth.

Another important change was the reduction of our Japanese and other Far East
holdings, a move that, fortunately, took place before the recent wave of
selling. Holdings in Europe, meanwhile, have been increased, with the United
Kingdom the single largest market, at 23% of the portfolio. Emerging markets
represent just 3% of the portfolio. The Series has less emphasis on cyclical
stocks and more on steady growth stocks, a position that we believe should be
beneficial in the uncertain period ahead.

The Series is run on a bottom-up basis; that is, we approach each stock as a
potential purchase candidate, as opposed to a top-down approach that develops an
overview of broad economies and markets, then follows through with stock
selection. In fact, both approaches use a little of each method, but the
difference in emphasis is important, and we believe in the long-term benefits of
our approach. We do not expect such a major transformation of the portfolio to
be repeated any time soon.

Money Market Series

For the year ended December 31, 1997, the Series provided a total return of
5.06%. Interest rates on short-term (30 days and less) debt instruments rose
approximately 40 basis points (0.40%) over the past 12 months. The Fed raised
short-term interest rates on March 25, 1997, by 25 basis points (0.25%), from
5.25% to 5.50%. The federal funds' rate remained at 5.50% for the rest of 1997.
Because of this, we maintained average maturities between 40 and 45 days.

We continue to limit the Series' investments to securities issued or guaranteed
by the U.S. Treasury or agencies or instrumentalities of the U.S. government, as
well as to the highest-quality corporate and bank issues, in an effort to
provide maximum security against credit risk. (Principal value and interest on
Treasury securities are guaranteed by the U.S. government if held to maturity.)
At the present time, approximately 62% of the portfolio is invested in U.S.
government or government-guaranteed issues, and the balance is invested in
corporate and bank issues. We expect short-term rates to be stable to slightly
lower over the next several months. The Series is neither insured nor guaranteed
by the U.S. government, and there can be no assurance that it will be able to
maintain a stable net asset value.

World Asset Allocation Series

For the year ended December 31, 1997, the Series provided a total return of
10.87%. This compares to 12-month returns for the following unmanaged indices:
33.36% for the Standard & Poor's 500 Composite Index (the S&P 500), a popular
index of common stock total return performance; 1.99% for the MSCI EAFE Index;
9.66% for the Lehman Brothers Aggregate Bond Index, an index of government and
corporate bonds including U.S. Treasury, agency, and corporate bond issues and
mortgage-backed securities; and 6.35% for the J.P. Morgan Non-Dollar Government
Bond Index, an index of international bonds.

We still feel that the U.S. equity market is overvalued and, thus, have
maintained an underweighted position in U.S. stocks. Because the worldwide
markets have shown more week-to-week volatility in recent months, we have
pursued a more tactical allocation approach, changing weightings more quickly in
the wake

2

<PAGE>

of market turbulence, and then returning to our original weightings. This
occurred just recently with U.S stocks, as we doubled our 10% allocation in
October after the market downdraft and then returned to our original 10%
weighting in December. We have also made this type of tactical move with
emerging-market debt and with the U.S. bond market. Currently, 48% of the Series
is allocated to international stocks, 7% to U.S. stocks, 3% to high-yield U.S.
bonds, 4% to a commodity-linked note, and 24% to cash.

World Governments Series

For the year ended December 31, 1997, the Series provided a total return of
- -0.76%. This compares to a 0.24% return for the Salomon Brothers World
Government Bond Index, an unmanaged index of complete universes of government
bonds with remaining maturities of at least five years. The dominant event for
world bond markets in 1997 occurred late in October with the economic crisis in
Southeast Asia. The sudden collapse in places such as Thailand, South Korea, and
Hong Kong resulted in severe devaluations of their currency, bond, and stock
markets. One of the more noticeable global effects during this period has been
stronger bond markets in most developed countries, especially in the United
States, as capital has sought a flight to quality in both the U.S.
currency and bond markets.

By the end of 1997, all bond markets in the Salomon Index had registered
positive returns in local currency terms. The better performers were the United
Kingdom, Italy, Australia, and Ireland, all of which helped the portfolio's
performance. The laggards were primarily the core European countries such as
Germany, the Netherlands, and France. Looking forward specifically to the
European countries, we see little opportunity for further yield convergence
prior to European monetary union and, therefore, the higher yielders that have
performed so well over the past 18 months should begin to perform more in line
with Germany.

During the year, the portfolio's nominal returns were significantly helped by
the strong bond markets. However, weaker currencies in Europe and Japan,
relative to the U.S. dollar, detracted from these positive returns. Relative to
the Salomon Index, the portfolio benefited by being overweighted in the
better-performing markets such as Italy and Australia.

The Asian crisis has created concern that global growth will slow sharply in
1998 and has reinforced the market's confidence that inflation will remain low,
if not decline. There is little doubt that the recovery process in Asia will be
slow and painful, but the magnitude of its impact on the rest of the world
remains to be seen. We believe slower global growth and lower inflation will
support core markets such as the United States and Germany and provide the
opportunity for further price appreciation if the downturn is more severe than
the market currently believes. Since most developed bond markets have done so
well over the past seven months, further sustainable downward pressure on
interest rates will now have to come through monetary stimulus from one or all
three of the primary central banks (the United States, Germany, and Japan),
which we feel will not occur in the near future.

Regarding the foreign exchange markets, over the long term we remain
constructive on the U.S. dollar versus both the Japanese yen and the German
mark. The U.S. currency should continue to be supported by higher interest rates
and a stronger economy than either Japan's or Germany's. In addition, we would
look for the Australian dollar, and especially the Canadian dollar, to rebound
from their low 1997 levels.

World Total Return Series

For the year ended December 31, 1997, the Series provided a total return of
13.61%. This compares to that of a benchmark made up of a combination of the
MSCI World Index (60%) and the J.P. Morgan Global Government Bond Index (40%),
which returned 10.33% for the same period. The MSCI World Index is an unmanaged
index of global equities, while the J.P. Morgan Global Government Bond Index is
an aggregate of actively traded government bonds issued by 13 countries,
including the United States, with remaining maturities of at least one year.
While the equity portion of the Series outperformed the MSCI World Index, it was
not a good year for bonds relative to stocks. One reason for the equity
portion's outperformance was that we generally avoided trouble areas such as the
Far East and were underweighted in Japan. Another reason for equity
outperformance was our significant position in pharmaceutical companies,
particularly those in the United States, which were outstanding performers.
Unfortunately, the bond portion of the Series, which accounts for about 40% of
assets, significantly underperformed comparative indices. Because of economic
uncertainties in several overseas economies, it just was not a good year for
foreign bonds.

Among regions, the Series was heavily weighted in Europe, particularly in some
of the smaller countries such as the Netherlands and Sweden. These countries
tend to spawn successful international companies, some of which have been very
attractive investments during the past 12 to 24 months. In Sweden, for example,
Astra has been a successful investment, while Ericsson, a telecommunications
company, Scandia, an insurance company, and Hennes & Maritz, a clothing
retailer, have also done well. We've actually sold the latter stock because its
price has surpassed our target level. In the Netherlands, IHC Caland, a company
that makes systems for oil dredging and shipping equipment, has also performed
well.

Although the pharmaceutical companies have done very well, and while some of
them have been sold because their prices went up so much, they still make up a
significant weighting for the Series. In the United States, this sector includes
companies like Eli Lilly, Schering Plough, and Bristol-Myers Squibb. It also
includes Japanese, Swedish, Swiss, and French drug companies, all of them
multinational.

The Series also has significant holdings in financial services and utilities and
communications. In many parts of the world, the biggest stocks are utilities and
bank and insurance companies. They tend to provide income. Also, in
faster-growing economies, utilities, which include telephone companies, are
growing at rates that are much more favorable than those in the United States.
There are very few U.S. utilities in the portfolio.

In the United Kingdom, the share has moved from 11% of Series assets to 14%. The
transition to the Labor government has been as smooth as one could hope for, and
a number of companies are performing well. One is British Aerospace, which may
benefit from the consolidation of the aerospace industry in Europe, as well as
from consolidation in the United States. Other companies of note include Lloyd's
Group, an innovative, consumer-driven bank, and Tomkins, a well-run conglomerate
that does not seem to be sufficiently appreciated by investors.

In the bond portion of the Series, we have focused on specific themes fairly
consistently, including the convergence of yields leading up to European
currency union. We have concentrated holdings in higher-yielding markets such as
Italy, Spain, Sweden,

                                                                               3

<PAGE>

Denmark and, more recently, the United Kingdom, all of which have outperformed
core markets like Germany. Another theme has been the disinflationary,
slow-growth environment in Japan. While many investors have shunned the low
yields on Japanese bonds, these declining yields have provided and continue to
provide capital gains. In the dollar-bloc countries, we continue to emphasize
the higher-yielding markets of Australia, Canada, and New Zealand, all of which
have outperformed the U.S. market. Although we were mistaken in shortening our
portfolio duration, or sensitivity to changes in interest rates, during the
first half of the year, the duration has been increased since the summer,
helping the Series benefit from the subsequent decline in yields.

Zero Coupon Series, 2000 Portfolio

The total return for the Series was 6.98% for the year ended December 31, 1997,
as intermediate-term U.S. Treasury notes moved lower during the period, with
yields on three-year Treasuries ranging from 6.25% to 5.75%. The portfolio
consists of discounted coupon or principal payments that are stripped from U.S.
Treasury securities in order to provide a predictable and compounded rate of
return. With no interest payments prior to maturity, these portfolios are more
sensitive to interest-rate changes than are comparable bond funds with similar
maturities. While there will be fluctuations within the portfolio subject to
interest-rate moves, all portfolio holdings are guaranteed by the U.S. Treasury
at maturity. (While the guarantees do not apply to the individual units of the
Series, they assure a specified return to contract owners who hold their units
to the maturity of the Series.)

MFS/Sun Life Series Trust
Notes to Financial Statements

(1) Organization
The Trust is organized as a Massachusetts business trust and is registered under
the Investment Company Act of 1940, as amended, as an open-end, management
investment company consisting of twenty separate Series (the Series) of shares:
Capital Appreciation Series, Conservative Growth Series, Emerging Growth Series,
Government Securities Series*, High Yield Series*, Managed Sectors Series,
MFS/Foreign & Colonial Emerging Markets Equity Series, International Growth
Series, International Growth and Income Series*, Money Market Series*, Research
Series, Research Growth and Income Series, Total Return Series, Utilities
Series, Value Series, World Asset Allocation Series*, World Governments Series*,
World Growth Series, World Total Return Series*, and Zero Coupon Series, 2000
Portfolio*. The High Yield Series, World Asset Allocation Series, World
Governments Series and World Total Return Series are nondiversified as that term
is defined in the Investment Company Act of 1940, as amended. The shares of each
Series are sold only to variable accounts established by Sun Life Assurance
Company of Canada (U.S.) and Sun Life Insurance and Annuity Company of New York
to fund benefits under variable annuity contracts issued by such companies.

The Series denoted with an asterisk above are included within these financial
statements.


(2) Significant Accounting Policies
General - The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. Investments
in foreign securities are vulnerable to the effects of changes in the relative
values of the local currency and the U.S. dollar and to the effects of changes
in each country's legal, political, and economic environment.

Investment Valuations - Equity securities listed on securities exchanges or
reported through the NASDAQ system are reported at market value using last sale
prices. Unlisted equity securities or listed equity securities for which last
sale prices are not available are reported at market value using last quoted bid
prices. Debt securities (other than short-term obligations which mature in 60
days or less), including listed issues, forward contracts, and interest rate
swaps, are valued on the basis of valuations furnished by dealers or by a
pricing service with consideration to factors such as institutional-size trading
in similar groups of securities, yield, quality, coupon rate, maturity, type of
issue, trading characteristics, and other market data, without exclusive
reliance upon exchange or over-the-counter prices. Short-term obligations, which
mature in 60 days or less, are valued at amortized cost, which approximates
market value. Money market instruments are valued at amortized cost, which the
Trustees have determined in good faith constitutes fair value. The Trust's use
of amortized cost is subject to the Trust's compliance with certain conditions
as specified under Rule 2a-7 of the Investment Company Act of 1940. Futures
contracts, options, and options on futures contracts listed on commodities
exchanges are reported at market value using closing settlement prices.
Over-the-counter options on securities are valued by brokers. Over-the-counter
currency options are valued through the use of a pricing model which takes into
account foreign currency exchange spot and forward rates, implied volatility,
and short-term repurchase rates. Securities for which there are no such
quotations or valuations are valued at fair value as determined in good faith by
or at the direction of the Trustees.

Repurchase Agreements - Certain Series of the Trust may enter into repurchase
agreements with institutions that the Trust's investment adviser has determined
are creditworthy. Each repurchase agreement is recorded at cost. Such Series
require that the securities purchased in a repurchase transaction be transferred
to the custodian in a manner sufficient to enable the Trust to obtain those
securities in the event of a default under the repurchase agreement. The
investment advisor monitors, on a daily basis, the value of the securities
transferred to ensure that the value, including accrued interest, of the
securities under each repurchase agreement is greater than amounts owed to the
Series under each such repurchase agreement. Certain Series of the Trust, along
with other affiliated entities of Massachusetts Financial Services Company
(MFS), may utilize a joint trading account for the purpose of entering into one
or more repurchase agreements.

Foreign Currency Translation - Investment valuations, other assets, and
liabilities initially expressed in foreign currencies are converted each
business day into U.S. dollars based upon current exchange rates. Purchases and
sales of foreign investments, income, and expenses are converted into U.S.
dollars based upon currency exchange rates prevailing on the respective dates of
such transactions. Gains and losses attributable to foreign currency exchange
rates on sales of securities are recorded for financial statement purposes as
net realized gains and losses on investments. Gains and losses attributable to
foreign exchange rate movements on income and expenses are recorded for
financial statement purposes as foreign currency transaction gains and losses.
That portion of both realized and unrealized gains and losses on investments
that result from fluctuations in foreign currency exchange rates is not
separately disclosed.

Written Options - Certain Series of the Trust may also write call or put options
in exchange for a premium. The premium is initially recorded as a liability
which is subsequently adjusted to the current value of the options contract.
When a written option expires, the Series realizes a gain equal to the amount of
the premium received. When a written call option is exercised or closed, the
premium received is offset against the proceeds to determine the realized gain
or loss. When a written put option is exercised, the premium reduces the cost
basis of the security purchased by the Series. The Series, as writer of an
option, may have no control over whether the underlying securities may be sold
(call) or purchased (put) and, as a result, bears the market risk of an
unfavorable change in the price of the securities underlying the written option.
In general, written call options may serve as a partial hedge against decreases
in value in the underlying securities to the extent of the premium received.
Written options may also be used as part of an income producing strategy
reflecting the view of the Series' management on the direction of interest
rates.

Notes to Financial Statements -- continued

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

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

Investment Transactions and Income - Investment transactions are recorded on the
trade date. Interest income is recorded on the accrual basis. All premium and
original issue discount is amortized or accreted for financial statement and tax
reporting purposes as required by federal income tax regulations. Dividends
received in cash are recorded on the ex-dividend date. Dividend and interest
payments received in additional securities are recorded on the ex-dividend or
ex-interest date in an amount equal to the value of the security on such date.

The High Yield Series can invest up to 100% of its portfolio in high-yield
securities rated below investment grade. Investments in high-yield securities
involve greater degrees of credit and market risk than investments in
higher-rated securities, and tend to be more sensitive to economic conditions.

As appropriate based on its investments, certain Series of the Trust use the
effective interest method for reporting interest income on payment-in-kind (PIK)
bonds. Legal fees and other related expenses incurred to preserve and protect
the value of a security owned are added to the cost of the security; other legal
fees are expensed. Capital infusions, which are generally non-recurring or
incurred to protect or enhance the value of high-yield debt securities, are
reported as an addition to the cost basis of the security. Costs that are
incurred to negotiate the terms or conditions of capital infusions or that are
expected to result in a plan of reorganization are reported as realized losses.
Ongoing costs incurred to protect or enhance an investment, or costs incurred to
pursue other claims or legal actions, are expensed.

Fees Paid Indirectly - The Series' custody fee is calculated as a percentage of
the Series' average daily net assets. The fee is reduced according to an
arrangement that measures the value of cash deposited with the custodian by the
Series. This amount is shown as a reduction of expenses on the Statement of
Operations.

Tax Matters and Distributions - Each Series or portfolio of the Trust intends to
comply with the provisions of the Internal Revenue Code (the Code) applicable to
regulated investment companies and to distribute to shareholders all of its
taxable income, including any net realized gain on investments. Accordingly, no
provision for federal income or excise tax is provided. The Series files a tax
return annually using tax accounting methods required under provisions of the
Code, which may differ from generally accepted accounting principles, the basis
on which these financial statements are prepared. Accordingly, the amount of net
investment income and net realized gain reported on these financial statements
may differ from that reported on the Series' tax return. Foreign taxes have been
provided for on interest and dividend income earned on foreign investments in
accordance with the applicable country's tax rates and to the extent
unrecoverable, are recorded as a reduction of investment income.

The Trust distinguishes between distributions on a tax basis and a financial
reporting basis and requires that only distributions in excess of tax basis
earnings and profits are reported in the financial statements as a tax return of
capital. Differences in the recognition or classification of income between the
financial statements and tax earnings and profits which result in temporary
over-distributions for financial statement purposes are classified as
distributions in excess of net investment income or accumulated net realized
gains. For the year ended December 31, 1997, the following amounts were
reclassified due to permanent differences between book and tax accounting for
currency transactions and paydown securities. These changes had no effect on the
net assets or net asset value per share.

(6) Financial Instruments
Certain Series of the Trust may trade financial instruments with
off-balance-sheet risk in the normal course of their investing activities and to
assist in managing exposure to market risks such as interest rates and foreign
currency exchange rates. These financial instruments include written options,
forward foreign currency exchange contracts, and futures contracts.

The notional or contractual amounts of these instruments represent the
investment the Series have in particular classes of financial instruments and do
not necessarily represent the amounts potentially subject to risk. The
measurement of the risks associated with these instruments is meaningful only
when all related and offsetting transactions are considered. A summary of
obligations under these financial instruments at December 31, 1997, is shown on
the following pages.

(7) Restricted Securities
Each Series of the Trust is restricted from investing more than a certain amount
of its net assets in securities which are subject to legal or contractual
restrictions on resale. Such restrictions range between 0% and 5% of the Series'
net assets. At December 31, 1997, the High Yield Series and World Asset
Allocation Series owned the following restricted securities (consisting of 0.17%
and 4.90% of the net assets of each series, respectively) which may not be
publicly sold without registration under the Securities Act of 1933. The Trust
does not have the right to demand that such securities be registered. The value
of these securities is determined by valuations supplied by a pricing service or
brokers, or, if not available, in good faith by or at the direction of the
Trustees.

Independent Auditors' Report

To The Trustees and Shareholders of MFS/Sun Life Series Trust:

We have audited the accompanying statements of assets and liabilities, including
the portfolios of investments, of Government Securities Series, High Yield
Series, International Growth and Income Series, Money Market Series, World Asset
Allocation Series, World Government Series, World Total Return Series and Zero
Coupon Series, 2000 Portfolio, (each a portfolio of MFS/Sun Life Series Trust as
of December 31, 1997, the related statements of operations for the year then
ended, the statements of changes in net assets for the years ended December 31,
1997 and 1996, and the financial highlights for each of the years in the
five-year period ended December 31, 1997. These financial statements and
financial highlights are the responsibility of the Trust's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of the securities owned at
December 31, 1997 by correspondence with the custodian and brokers; where
replies were not received from brokers, we performed other auditing procedures.
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of the Trust at
December 31, 1997, the results of its operations, the changes in its net assets,
and its financial highlights for the respective stated periods in conformity
with generally accepted accounting principles.
