Letter from the Chairman

Dear Contract Owners:

With the U.S. stock market well into its fourth year of record-breaking
advances, it is necessary to take a cautious outlook. By most commonly accepted
measures, equity valuations appear to have risen to a point at which the stock
market has become more vulnerable to changes in the investment environment such
as rising inflation and interest rates or a slowing economy. As a result, while
we continue to hold a favorable long-term outlook for the equity markets, we
also believe that a significant market correction is possible and that such a
correction would be a healthy near-term event.

Currently, equity investors seem to be primarily focused on interest rates,
which have been relatively stable for several months as inflation has remained
low. In an environment of low interest rates, stocks become more attractive than
most fixed-income investments, while low inflation helps control companies'
costs, such as for raw materials, wages, and benefits. The near-term outlook for
a continuation of this environment appears relatively favorable. However, this
year has seen a marked slowdown in corporate earnings. This means that as equity
prices continue to rise, price-to-earnings (P/E) ratios, or the amount an
investor pays for a stock in relation to the company's earnings per share, also
go up. A year ago, the average P/E ratio for stocks in the unmanaged Standard &
Poor's 500 Composite Index stood at approximately 22; this summer, the average
P/E ratio was 32% higher, at about 29. In some cases, such as with some of the
newer companies associated with the Internet, P/E ratios have soared to levels
that are unlikely to be sustained.

As long as interest rates remain low and the economy continues to grow, it is
possible that some of these valuations can be supported. We expect corporate
earnings to grow 4% to 6% this year. However, just as no one can predict market
cycles, so too no one can predict economic cycles -- except to say that these
cycles do exist and that an economic slowdown at some point is inevitable.

Internationally, the economic turmoil in Asia continues to be a concern to us,
and we believe the United States has yet to see the full impact of this crisis.
There have been brief periods when some Asian economies appeared to improve, but
the situation remains quite dynamic and could turn worse before getting better.
While the crisis has affected all countries in Asia, Japan was a major factor
behind the turmoil as excesses in its banking and real estate sectors have led
to severe currency problems. In the long run, Japan will be the engine that
drives the region's eventual recovery, thus it warrants closer investor
scrutiny. At the same time, the Asian turmoil has had the beneficial effect of
moderating U.S. growth and keeping inflation in check, which has helped
establish a favorable interest-rate environment.

Countering the situation in Asia has been the greater-than-expected strength of
European economies. As Europe moves toward economic union, these countries have
benefited from a convergence of interest rates to lower levels, a rapid
expansion of manufacturing and service businesses, and an increasingly strong
consumer sector. This has helped American exporters offset some of their Asian
losses, while providing numerous investment opportunities in developed and
emerging European markets.

Given the uncertainty arising from these conflicting developments, we believe it
is prudent to remind investors of the need to take a long-term view and to
diversify their investments across a range of asset classes. This includes
portfolios that focus on bonds and international investments as well as on the
U.S. stock market. The likelihood of an eventual market correction also makes it
important for us to use original, bottom-up research to find companies that we
think can keep growing or gain market share in the face of the occasional
downturn. To help achieve this, and to provide the broadest possible coverage of
industry sectors and individual companies, MFS continues to increase its number
of full-time research analysts. These analysts thoroughly investigate each
company's earnings potential and position in its industry as well as the overall
prospects for that industry.

MFS also uses active portfolio management on the fixed-income side, taking
advantage of our extensive research and credit analysis to help reduce the
potential for price declines and enhance the opportunity for appreciation. Every
year, both fixed-income and equity managers meet with thousands of credit
issuers and companies. They also attend many presentations, closely follow
sources of industry research, and keep track of competitors.

We believe that applying this discipline of thorough, bottom-up research to both
the equity and fixed-income markets is the best way to provide favorable
long-term performance for our shareholders -- regardless of changes in the
overall market environment.

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,

/s/ John D. McNeil

Management Review and Outlook

Bond Series
The Series commenced operations on May 6, 1998, and from that date through June
30, 1998, provided a total return of 2.00%.

The Series currently is overweighted in investment-grade corporate bonds and
high-yield securities. We expect to have, on average, a 50% weighting in
investment-grade corporates and roughly 20% in the high-yield market, which is
the Series' maximum allocation. The Series has almost no allocation to
international government bonds, based on our view that yields have converged
among the United States, Germany, and the other European countries at 6%. Thus,
we think the United States is the most attractive market. Inflation in the
United States is low, its economy is strong, and it has the market leaders in
many major industries, most notably in technology and telecommunications.

Currently, the Series' duration, or sensitivity to changes in interest rates, is
about seven years, which is its usual maximum. This reflects our view that, with
inflation at about 1.5%, and 10-year U.S. Treasuries at around 5.5% and perhaps
moving down a little, the environment for fixed-income securities is very
attractive.

Looking ahead, the biggest risks to the bond market are the possibility of the
U.S. economy growing too fast and the Asian slowdown that people are counting
on not developing. If economic

Management Review and Outlook -- continued

growth continues at a 4% to 5% annual rate, there's no Asian-induced slowdown,
and we start to see some early signs of inflation, the Federal Reserve Board
(the Fed) could be forced to raise short-term interest rates, even if there
still are no inflation pressures. However, if interest rates and inflation
remain steady and the U.S. economy continues to grow at a moderate pace, which
is what we expect, it will be a positive environment for investment-grade
corporate and high-yield bonds, as well as for some of the emerging markets,
which are very sensitive to changes in short-term interest rates.

Government Securities Series
For the six months ended June 30, 1998, the Series provided a total return of
3.91%. This compares to a 3.87% return for the Lehman Brothers
Government/Mortgage Index (the Lehman Index), an unmanaged index of U.S.
Treasury, government-agency, and mortgage-backed securities.

To most investors, the surprise of this year has been that robust economic
growth, especially this late in the economic cycle, has coincided with a
dramatic improvement in inflation trends and an overall decline in interest
rates. Even though economic activity for much of the year exceeded a level that
the Fed would consider noninflationary, and in spite of the fact that the Fed
increased the federal funds rate to 5.50% in March of 1997, two trends have
worked in favor of the market and helped lower rates. The first was the sharp
decline in the U.S. government's borrowing needs. In fact, for the 12-month
period ended June 1998, the government was running a surplus of about $56.2
billion, and for the fiscal year ending this October the surplus may be somewhat
higher. The second favorable trend was the decline in inflation. Much to the
surprise of most economists, inflation fell significantly over the course of the
year, with the Consumer Price Index, for example, declining to 1.70% in 1997
from 3.30% in 1996.

The fixed-income environment, although at times volatile, was generally positive
over the past six months. With the general decline in interest rates, coupon
income was augmented by opportunities for capital appreciation, particularly in
longer-maturity securities. For example, an investment in the two-year sector
would have returned 2.90%, whereas the total return in the 10-year sector was
4.27%. With household income, job growth, and consumer confidence quite strong,
the rally in shorter maturities was somewhat limited by concerns that the Fed
would again find it necessary to raise short-term interest rates. The very
favorable performance on the inflation and fiscal fronts, however, provided a
very positive underpinning for Treasuries, one from which longer maturities were
able to benefit. This environment benefited the Series, given our overweighting
in longer-maturity Treasury and agency securities.

For most of this year, the Series' duration, or sensitivity to changes in
interest rates, has been 5% to 10% longer than those of the appropriate
benchmarks. Strength in employment and overall economic activity, along with the
risk that the Fed might raise interest rates, argued for caution. Thus, we have
not positioned duration more aggressively. The many positive underpinnings to
the market, however, did suggest that we should position the portfolio to
benefit from opportunities for capital appreciation as fears of Fed action
receded.

Looking ahead, the economic environment, especially prospects for the
fixed-income market, should be especially positive. The supply-side nature of
the economic expansion (with growth in supply outstripping that of demand) and
the boom in global production capacity have helped suppress inflation. Declining
inflation at this stage of the economic expansion is remarkable, and any
slowdown in economic growth could quickly trigger even lower inflation
expectations. Investors, however, have yet to embrace the idea that the economy
is at or close to price stability. Although the economy shows few signs of
weakening, interest rates will have considerable room to fall after economic
activity cools and the view that we are indeed close to the long-term objective
of price stability becomes more broadly accepted.

High Yield Series
For the six months ended June 30, 1998, the Series provided a total return of
5.30%. This compares to a 4.50% return for the Lehman Brothers High Yield Bond
Index. The high-yield market is experiencing an unprecedented period of growth
and strong performance and continues to be the best-performing domestic
fixed-income asset class. So far this year, a record $97 billion of high-yield
bonds has been issued by 422 companies, and the market has surpassed $570
billion in bonds outstanding. Healthy economic growth has contributed to the
market's performance as companies have continued to post improved operating
results.

The spread, or difference, between yields on high-yield bonds and U.S. Treasury
notes has widened recently as some global equity investors have sought the
security of the Treasury market following renewed concerns about economic
problems in Asia. (Principal value and interest on Treasury securities are
guaranteed by the U.S. government if held to maturity.) As a result of this
flight to quality, the yield on Treasury notes fell slightly, to 5.4%, while the
yield on the Salomon Brothers High-Yield Bond Index, an unmanaged index of
noninvestment-grade U.S. corporate debt, remained at 9.2%. Given the low level
of interest rates, we believe the high-yield market remains attractively valued,
with the spread to Treasuries at 3.8%, its widest level in two-and-a-half years.

While the economic slowdown in Asia could adversely affect the U.S. economy, we
do not think it will materially impact the credit quality of the high-yield
companies owned by the Series. The Series is primarily invested in the bonds of
domestic companies, and when the crisis in Southeast Asia developed last fall we
reduced our holdings in companies with high exports to that area.

We believe that many high-yield telecommunications issues continue to represent
good value, given their growth opportunities and the higher yields available in
this sector. The telecommunications sector is our largest industry overweighting
and has been one of the best-performing sectors in the high-yield market over
the past 12 months. The Series is also overweighted in the aerospace sector, in
which equipment suppliers such as BE Aerospace are benefiting from strong orders
for new commercial aircraft. Our portfolio is underweighted in the energy
sector, but we will look for investment opportunities in this area because
recently yields have risen in response to oil prices sinking to their lowest
levels in 12 years.

International Growth and Income Series
For the six months ended June 30, 1998, the Series provided a total return of
19.65%. This compares to a 15.81% return for the unmanaged Lipper International
Funds Index and to a 16.08% return for the Morgan Stanley Capital International
(MSCI) Europe, Australia, Far East (EAFE) Index, an unmanaged, market-
capitalization-weighted total return index of developed-country global stock
markets, excluding the United States, Canada, and the South African mining
component.

The Series is managed 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 picks stocks based on that overview. Although both approaches
borrow from each other, we feel the difference in emphasis is important, and we
believe in the long-term benefits of our bottom-up approach.

The Series has benefited from its heavy weighting in stocks in Europe. Europe
looks relatively good due to strong earnings growth in several countries there.
The Series also benefited from its light weighting in the Far East, especially
in Japan, and minimal exposure to emerging markets. The better-performing
countries include some of the smaller ones such as Sweden, the Netherlands,
Italy, and Portugal. International companies in Sweden and the Netherlands are
doing particularly well. Favorable individual company performance has come from
Pinault-Printemps-Redoute, a French department store chain; Compass Group, a
British food caterer; Henkel, a German chemical company; British Aerospace;
Skandia, a Swedish insurance company; Banco Totta, a Portuguese bank; INA, an
Italian insurance company; and TF-1, a French television company.

The companies in the Series tend to have steady earnings. This applies to
consumer staples, financial services, and telecommunications companies. The only
sector with a heavy weighting that doesn't fit this pattern is technology. Even
there, the technology companies in the Series tend to be manufacturers such as
Canon, as opposed to the more volatile industries such as semiconductors.

While there is some risk that investors will decide that the European markets
have gone up about as far as they can for the time being and that they're too
expensive, Europe and the United States still appear to be the most attractive
places to invest right now.

Looking ahead, we think the companies in the Series are going to continue to
benefit from low inflation and low interest rates. The rippling effect of the
economic crisis in the Far East is causing a slowdown in many other countries
and will have to be monitored carefully.

MFS(R)/Foreign & Colonial Emerging Markets Equity Series
For the six months ended June 30, 1998, the Series provided a total return of
- -17.54%. This compares to a -17.00% return for the Lipper Emerging Markets Funds
Index and to a -18.86% return for the MSCI Emerging Markets Free (EMF) Index, a
broad, unmanaged, market-capitalization-weighted index of equities in emerging
markets.

The emerging markets have continued to be quite volatile due to the Asian
crisis, which has led to worries over its spreading to other regions. Among the
primary causes for this crisis were high levels of foreign borrowing by both the
government and corporate sectors, poor returns on investments, overvalued
currencies pegged to the U.S. dollar, and high equity prices. This has caused
some roller-coaster stock market performances in countries such as Brazil,
Turkey, and Russia. The Asian crisis and the economic health of Japan led to
tightening liquidity in the region, although in recent months the situation has
eased due to financial assistance from international aid agencies such as the
International Monetary Fund (the IMF).

Although we believe the crisis will take several years to be resolved fully, we
are seeing the first signs of a recovery in the willingness of governments in
the region to undertake structural reform with the help of the IMF. The next
stage will be to recapitalize the banking sector and encourage corporate
bankruptcies. Foreign capital will then begin to move back into the region,
although we also expect significant political change following the precedent set
by the resignations of President Suharto in Indonesia and Prime Minister
Hashimoto in Japan.

Given this environment, we have kept a low weighting in Southeast Asia (taking
positions down to nearly zero in Thailand, Indonesia, the Philippines, and
Malaysia), preferring to overweight Eastern Europe, the Middle East, and Latin
America. Specifically, our exposure to Brazil, Mexico, Egypt, and Morocco has
helped performance, while our exposure to markets in Hong Kong, China, and
Poland has hindered performance. However, we are still finding what we believe
are interesting companies in Hong Kong, China, and India. For example, we
believe Qingling Motors, the leading pickup truck manufacturer in China, will
benefit from cheaper parts imported from Japan. The compound annual growth rate
for these companies' earnings over the past two years has been approximately 75%
and, with new launches expected over the next year plus superior product
quality, we believe this growth level will be maintained.

Turning to other markets, Latin America initially benefited from the Asian
crisis as international investors turned toward the region. More recently, the
currency crisis in Asia has led to worries about the Mexican peso and the
privatization program in Brazil. The medium-term outlook for the region looks
encouraging because economies have reduced their structural imbalances and the
banking sector has recapitalized.

Among other emerging markets, the European, Middle Eastern, and African regions,
or the EMEA, remain our favorite areas. Although Portugal looks expensive
following its spectacular rise, Egypt remains an excellent value, and we have
added significantly to our positions in South Africa because we expect inflation
and interest rates there to gradually decline during the year.

Looking ahead, we believe that at current levels emerging markets are very
attractive compared with developed markets, although we remain cautious on Asia,
neutral on Latin America, and positive on the EMEA region.

Money Market Series
Interest rates on short-term (90-day) securities remained stable during the past
six months. The Fed did not adjust monetary policy, thus the federal funds rate
remained at 5.50% for the entire period. At the present time, approximately 54%
of assets are invested in U.S. government or government-guaranteed issues, with
the balance in corporate and bank issues. The average maturity of the Series on
June 30, 1998, was 39 days, versus 42 days on December 31, 1997. 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 order to provide maximum
security against credit risk.

We expect short-term interest rates to be flat over the next several months.

Strategic Income Series
The Series commenced operations on May 6, 1998, and from that date through June
30, 1998, provided a total return of 1.10%.

It's been a mixed environment for bonds so far this year. However, the portfolio
invests across several types of credit, so when one type of bond is under
pressure, often another type will perform well. The U.S. high-yield corporate
sector is benefiting from


                                                                               3
<PAGE>

Management Review and Outlook -- continued

a strong U.S. economy, a strong stock market, and a worldwide shortage of
investments with good yields. Additionally, a number of high-quality companies
have acquired high-yielding companies, which has boosted the quality of the
acquired bonds. As a result, people looking for higher yield have put more money
into high-yield investments.

Regarding Asia, we feel the economic problems there have a way to go before they
are resolved, so we have limited our Asian exposure until the markets present a
more attractive buying opportunity. In the future, perhaps six months or more,
there will be opportunities to invest in Asian corporate and government debt.

Europe is showing economic strength right now, which is improving European
credit ratings but pushing interest rates down, and the convergence of countries
into a single economic bloc is reducing the difference between each country's
yield, diminishing the value of government debt and limiting investment
opportunities.

We had been concerned that, due to the extreme inflation of the value of U.S.
assets, particularly stock and real estate prices, the Fed would raise interest
rates. The turmoil in Asia seems to have dissuaded it from taking action at this
time. Further inaction should preserve bond prices at higher levels.

We are optimistic about the worldwide environment for bonds. If we have a major
concern, it is that the world may have excess liquidity at the moment, which has
been a factor in the run-up in the equity markets. There is a possibility that
some of this liquidity will be withdrawn from world markets to combat the
troubles in Asia. If this happens, it will negatively impact the stock market,
which could be favorable for the bond market.

World Asset Allocation Series
For the six months ended June 30, 1998, the Series provided a total return of
9.84%. This compares to six-month returns for the following unmanaged indices:
17.71% for the Standard & Poor's 500 Composite Index (the S&P 500), a popular
index of common stock total return performance; 17.12% for the MSCI EAFE Index;
3.93% 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 2.66% for the J.P. Morgan Non-Dollar Government
Bond Index, an index of international bonds.

Except for Asia, the world's equity markets have performed extremely well since
1991. As a result, people are investing heavily in equities, sometimes to the
detriment of the diversity of their portfolios. To better balance this
situation, the Series seeks to maintain a diverse global portfolio that will
provide investors with a number of nonlinked investment vehicles.

As a result of the dynamic worldwide investment environment, the Series is
overweighted in international equities, at a targeted allocation of 50% of
assets. We've doubled the targeted U.S. equity allocation to 20%, but that is
still an underweighting. Our bond position is focused on U.S. high-yield
corporate issues because we feel that we can take advantage of the continuing
consolidation between high-yield and investment-grade companies. This trend has
been buoyed by a resilient U.S. economy, and we remain optimistic about the
sector even though U.S. economic growth is slowing. We've devoted 8% of our
allocation to long-duration U.S. Treasury securities to take advantage of better
prices stemming from the low-inflation scenario and federal budget surpluses.

We remain committed to meeting the Series' objective of providing competitive
total returns with relatively low volatility over a reasonable business cycle,
while seeking to mitigate market risks through research and broad
diversification.

World Governments Series
For the six months ended June 30, 1998, the Series provided a total return of
1.58%. This compares to a 2.78% return for the Salomon Brothers World Government
Bond Index (the Salomon Index), an unmanaged index of complete universes of
government bonds with remaining maturities of at least five years. The Series is
replacing the JP Morgan Global Government Bond Index (an aggregate of actively
traded government bonds issued by 13 countries including the United States, with
remaining maturities of less than one year) with the Salomon Index because we
feel the Salomon Index better reflects the universe in which the Series invests.

For the past six months, the Asian economic crisis has been the largest factor
in determining the global environment for bond investing. The slowdown in growth
that has resulted from the Asian problem, combined with a lack of inflation, has
resulted in a very positive environment for almost all bond markets in developed
countries. Given these conditions, we had expected that the three major central
banks -- those in the United States, Germany, and Japan -- would leave interest
rates unchanged. This expectation has proven accurate and we believe that,
absent inflationary signs, the Fed will continue to put off raising rates as
long as economic turmoil exists in Southeast Asia.

By the end of June, the Japanese appeared to be getting closer to addressing
their severe banking problems as well as offering badly needed income tax cuts
in order to stimulate their depressed economy. However, markets will remain
skeptical until firm policies are put into place and acted upon. Meanwhile,
Western Europe continues to prepare itself for the initial phase of European
monetary union, which is set to begin in January 1999. This will be a huge and
significant undertaking that will take years to fully implement.

Year-to-date returns for all bond markets in the Salomon Index registered
positive returns when measured in local terms (not adjusted for currency
differences). The better performers have been Sweden and the United Kingdom, and
Japan has been the worst. The Series has benefited from being overweighted in
the United Kingdom and underweighted in Japan. Performance relative to the index
was hurt by overweighting the United States, which underperformed at the
beginning of the year.

Our views have not dramatically changed from the beginning of the year. The
inflation outlook, fiscal progress in several regions of the world in lowering
budget deficits, and increasing global competition are some of the very
favorable factors that we believe will continue to lower global interest rates.
Many bond markets have already discounted these positive developments. For
interest rates to drop significantly from their current low levels, the
Southeast Asian economies would have to continue unraveling, thereby causing
central banks to ease monetary policy and put more currency into their
respective economies. However, we do not foresee this scenario coming to pass in
the near future.

Meanwhile, the direction of both the Japanese economy and the yen will be
critical for most fixed-income markets in the months ahead. We continue to
believe the bond markets with the highest real and nominal interest rates will
perform well. Consequently, we expect to maintain our overweighted position in
the U.S. bloc, with underweightings in both the European and Japanese blocs.

Management Review and Outlook -- continued

World Total Return Series
For the six months ended June 30, 1998, the Series provided a total return of
11.03%. 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 11.31% 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.
Over the same period, the Lipper Global Flexible Fund Index returned 8.21%.

The Series has benefited from this year's improved performance of several
foreign stock markets relative to U.S. markets. While the U.S. markets have
performed well, some European markets have done even better, not only in local
currency terms but also in dollar terms. At the same time, the Series has been
helped by the fact that the weighting in the Far East, including in Japan, has
been relatively light.

While Europe has been the strongest region in the world, even there it has been
a stock-picker's market, one that stresses individual company selection over
country selection, which is how the Series is managed. The list of holdings that
were key contributors includes stocks from Portugal, Canada, the United Kingdom,
Germany, Sweden, France, and the Netherlands. Stocks include Scandia,
Mannesmann, Compass Group, Pinault Printemps Redoute, and Williams.

The Series' biggest industry weighting is in financial services, which includes
banks, insurance companies, and miscellaneous financial companies. While it has
been an area of very strong performance for a very long time, we believe we
might be approaching the end of the period of strong performance for some of
these companies. These stocks benefit from declining interest rates, and it
appears that most of that phenomenon has taken place.

Another large sector is consumer staples. Here, we look for companies with
stable and growing earnings. That includes companies like Wella, a cosmetics
company in Germany; Foster's Brewing, a beer company in Australia; and Kirin
Beverage in Japan.

In the Series' bond portion, we recently began switching assets back to the U.S.
and German markets after concentrating on the higher-yielding European bond
markets for the past 18 months, which had enabled us to benefit from the
convergence of yields leading up to European monetary union. We believe most of
the European convergence is behind us and that the U.S. bond market offers
better relative value based on both real (inflation-adjusted) and nominal rates.
While most economies in Europe are recovering, the United Kingdom is beginning
to falter due to an overvalued currency and relatively high interest rates. As a
result, we have increased our bond holdings in the United Kingdom. Globally,
inflation remains quite benign and, in some countries, is actually falling. We
feel this will help maintain the constructive tone in most bond markets.

Zero Coupon Series, Portfolio 2000
The total return for the Series was 2.97% for the six months ended June 30,
1998, as intermediate-term U.S. Treasury notes moved lower during the period,
with yields on two-year Treasuries ranging from 5.30% to 5.70%. 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.)

</TABLE>

All results are historical and assume the reinvestment of dividends and capital
gains. Investment return and principal value will fluctuate, and shares, when
redeemed, may be worth more or less than their original cost. Past performance
is no guarantee of future results. Performance results reflect any applicable
expense subsidies and waivers, without which the results would have been less
favorable. Subsidies and waivers may be rescinded at any time. See the
prospectus for details.

Returns shown do not reflect the deduction of the mortality and expense risk
charges and administration fees. Please refer to the annuity product's annual
report for performance that reflects the deduction of the fees and charges
imposed by insurance company separate accounts.

1 Government guarantees apply to individual securities only and not to prices
and yields of shares in a managed portfolio.

2 Lower-rated securities may provide greater returns, but they are also
  associated with greater-than-average risk. These risks may increase share
  price volatility.

3 Investments in foreign and emerging market securities may provide superior
  returns but also involve greater risk than U.S. investments. Investments in
  foreign and emerging market securities may be favorably or unfavorably
  affected by changes in interest rates and currency exchange rates, market
  conditions, and the economic and political conditions of the countries where
  investments are made. These risks may increase share price volatility.

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-six separate Series (the Series) of
shares: Bond Series*, Capital Appreciation Series, Capital Opportunities Series
(formerly known as Value Series), Conservative Growth Series, Emerging Growth
Series, Equity Income Series, Government Securities Series*, High Yield Series*,
International Growth Series, International Growth and Income Series*, Managed
Sectors Series, MFS[RegTM]/Foreign & Colonial Emerging Markets Equity Series*,
Money Market Series*, Massachusetts Investors Growth Stock Series, New Discovery
Series, Research Series, Research Growth and Income Series, Research
International Series, Strategic Income Series*, Total Return Series, Utilities
Series, World Asset Allocation(SM) Series*, World Governments Series*, World
Growth Series, World Total Return Series*, and Zero Coupon Series, Portfolio
2000*. The High Yield Series, Managed Sector Series, Strategic Income Series,
Utilities Series, World Asset Allocation(SM) Series, World Governments Series,
World Growth 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 swap agreements,
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 approximates 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 collateral in a repurchase transaction be transferred to the
custodian in a manner sufficient to enable the Trust to obtain those securities
in the event of a default under the repurchase agreement. The investment advisor
monitors, on a daily basis, the value of the collateral to ensure that its
value, including accrued interest, is greater than amounts owed to the 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 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. In entering such contracts,
the Series is required to deposit with the broker, either in cash or securities
an amount equal to a certain percentage of the contract amount. Subsequent
payments are made or received by the Series each day, depending on the daily
fluctuations in the value of the contract, and are recorded for financial
statement purposes as unrealized gains or losses by the 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 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.

Swap Agreements - Certain Series of the Trust may enter into swap agreements. A
swap is an exchange of cash payments between a Series and another party which is
based on a specific financial index. Cash payments are exchanged at specified
intervals and the expected income or expense is recorded on the accrual basis.
The value of the swap is adjusted daily and the change in value is recorded as
unrealized appreciation or depreciation. Risks may arise upon entering into
these agreements from the potential inability of counterparties to meet the
terms of their contract and from unanticipated changes in the value of the
financial index on which the swap agreement is based. The Series uses swaps for
both hedging and non-hedging purposes. For hedging purposes, the Series may use
swaps to reduce its exposure to interest and foreign exchange rate fluctuations.
For non-hedging purposes, the Series may use swaps to take a position on
anticipated changes in the underlying financial index.

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.

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 nonrecurring 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' month end 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' policy is to comply with the
provisions of the Internal Revenue Code (the Code) applicable to regulated
investment companies and to distribute to shareholders all of its taxable
income, including any net realized gain on investments. Accordingly, no
provision for federal income or excise tax is provided. The Series' file tax
returns 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 returns. 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.


                                                                              41

(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 in
order to manage exposure to market risks such as interest rates and foreign
currency exchange rates. These financial instruments include written options,
forward foreign currency exchange contracts, futures contracts, and swap
agreements.

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 June 30, 1998, is shown below
and 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 June 30, 1998, the High Yield Series, MFS[RegTM]/Foreign &
Colonial Emerging Market Equity Series and World Asset Allocation(SM) Series
owned the following restricted securities (consisting of 0.37%, 0.19% and 4.19%
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.

(8) Line of Credit
The Trust and other affiliated funds participate in a $805 million unsecured
line of credit provided by a syndication of banks under a line of credit
agreement. Borrowings may be made to temporarily finance the repurchase of
Series shares. Interest is charged to each Series, based on its borrowings, at a
rate equal to the bank's base rate. In addition, a commitment fee, based on the
average daily unused portion of the line of credit, is allocated among the
participating funds at the end of each quarter.

Colonial Emerging Markets Equity Series, Money Market Series, Strategic Income
Series, World Asset Allocation(SM) Series, World Government Series, World Total
Return Series and Zero Coupon Series, Portfolio 2000, (each a portfolio of
MFS/Sun Life Series Trust), as of June 30, 1998, the related statements of
operations for the six months then ended, the statements of changes in net
assets for the six months then ended and for the year ended December 31, 1997,
and the financial highlights for the six months then ended and each of the years
in the five years 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 June
30, 1998 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 June
30, 1998, 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.
