Dear Contract Owners:
An unprecedented combination of generally positive factors has helped the U.S.
economy enjoy a sustained period of relative stability and moderate growth in
which thousands of new jobs have been created every month, inflation remains
under control, and the investment climate -- at least until now -- has been
favorable. For example, 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. Meanwhile,
borrowing by corporations and governments continues to decline, while consumer
confidence is increasing, although consumer debt levels are still uncomfortably
high. While some lenders are beginning to tighten standards to address this
problem, consumer debt and personal bankruptcies continue to rise. Because of
this, plus slight declines in other indicators such as average hourly wages and
the corporate purchasing-managers index, we do not expect the rapid pace of
growth seen in the first quarter of 1997 to continue. While second-quarter
growth has slowed dramatically, we do expect the second half of the year to
pick up once again with real (inflation-adjusted) growth centering around
2-1/2%.

Global Outlook
Increased liquidity has continued to support international equity markets this
year, while disinflationary forces have continued despite somewhat stronger
world economic growth. While the strength of the U.S. dollar versus the
Japanese yen earlier this year resulted in stronger performance for Japanese
exporters, the value-added tax seems to have slowed the overall Japanese
economy. In Europe, meanwhile, uncertainty over European monetary union
continues, although stocks of some European companies have benefited from
restructuring and the use of technology to increase productivity. Perhaps the
brightest international story has been the performance of the emerging markets,
all of which have seen rapidly expanding economies and higher earnings, thanks
in part to significant shifts in their economic policies.

Bond Markets
In the fixed-income markets, we have been encouraged by the Federal Reserve
Board's decision to not raise short-term interest rates at its July meeting.
But we cannot rule out the possibility of future monetary tightening in the
second half of the year if, as we now expect, the economy strengthens in the
second half of 1997. Therefore, our risk/reward outlook for the fixed-income
markets is neutral, and we believe that fixed-income investors should think in
terms of earning the coupon income from their investments rather than seeking
possible gains from price appreciation.

Stock Market
We have been surprised by the strength of the U.S. equity market in the first
half of 1997. Much of this is the result of continuing gains in corporate
earnings. Even as the current recovery enters its seventh year, more and more
U.S. companies have been exceeding analysts' earnings estimates. In the first
quarter of 1997, for example, two-thirds of all companies met or exceeded
analysts' expectations, a trend that could be an important indicator of the
U.S. equity market's future direction. However, while the near-term outlook for
profits is generally favorable, we believe equity valuations have risen to a
point where a cautious investment approach seems warranted.

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 these charges been deducted. We
appreciate your support and welcome any questions or comments you may have.

On behalf of the Board of Trustees,

Capital Appreciation Series
For the six months ended June 30, 1997, the Series provided a total return of
15.28%, which compares to a 20.60% return for the Standard & Poor's 500
Composite Index (the S&P 500), an unmanaged index of common stock total return
performance. The Series has benefited from an increased weighting in large-
capitalization stocks with consistent earnings growth, such as Tyco
International, United Technologies, and Bristol-Myers Squibb, all of which were
significant performers in the first half of the year. Tyco, which will merge
with ADT Ltd. in early July, is a diversified manufacturing company whose
complementary acquisitions, as well as its high-quality management team, could
result in high earnings growth over the next three years, adding to contract
owners value.

In the technology sector, the Series' largest, stocks in businesses such as
computer software, semiconductors, and networking added to performance during
the period, although this weighting has been reduced slightly over the past six
months. Large technology holdings such as Oracle Systems and Computer Associates
are major beneficiaries of the deployment of client/server technology in the
corporate environment. Personal computer companies such as Microsoft, which
develops operating systems and application software, continue to report very
strong earnings growth. This sector can be volatile at times, but we believe its
high, long-term past performance results make it attractive. It is important to
emphasize that the companies in this sector are selected individually and that
the large weightings represent the number of well-positioned companies we have
identified in this area.

Other holdings in the Series such as Intel Corp., HFS, Inc., and Wisconsin
Central Transportation underperformed the S&P 500 during the first half, but we
continue to view them as attractive investments. For example, HFS, Inc., which
owns a number of hotel, rental car, and real estate franchise systems,
continues to benefit from higher hotel room rates and increased occupancy.
Also, the Series maintains a significant weighting in mid-capitalization
stocks, which significantly underperformed the S&P 500 as a group.

Finally, this period of moderate economic growth and inflation has provided a
positive backdrop for further growth in corporate earnings and continued
appreciation of the stock market. Cash levels have been raised as a buying
reserve should any market correction occur. We remain committed to finding the
best earnings growth available, at the most reasonable valuations, in trying to
shape the Series for the future.

Conservative Growth Series
For the six months ended June 30, 1997, the Series provided a total return of
18.97%, which compares to a 20.60% return for the S&P 500. The Series' slight
underperformance versus the S&P 500 during the past six months can be
attributed to four

                                                                               1

sectors: energy, health care, industrial goods and services, and
transportation. The companies held in the Series in each of these sectors are
leaders in their respective industries and, overall, performed well during the
period; however, they were unable to maintain the torrid pace of equivalent
sectors in the S&P 500. The Series did outperform the S&P 500 in the financial
services, basic materials, technology, leisure, and utilities and
communications sectors during the period.

Sector weightings in the Series have shifted slightly. Most notably, the health
care sector increased by 2.2%. Select pharmaceutical companies have introduced
new products that have been well received, resulting in strong revenue growth.
In addition, the slow-growth, low-inflation economic environment has allowed
choice banks and insurance companies to flourish during the first half of 1997,
and many of the banking and insurance stocks in the Series have performed well.

Several companies within the chemical and specialty chemical industries,
including du Pont, Air Products and Chemicals, and Praxair, have also enhanced
the Series' return. These companies have achieved strong stock performance
through focused cost-savings efforts and the introduction of new, higher-margin
products and services that have complemented their existing product lines.

The Series' weighting in the technology sector increased 1.8% during the past
six months. Several stocks within this sector contributed positively to the
Series' performance, including Microsoft, BMC Software, Sony Corp., and Lucent
Technologies. These companies have developed what we regard as solid
competitive positions within their industries that have translated into
successful stock performance. We believe that the earnings outlook for all of
the technology companies held in the Series remains strong.

The Series remains underweighted in energy, automobiles and housing, and
utilities and communications. While individual stocks within these sectors can
positively contribute to the Series' return, we have determined that the
earnings outlook for many of the companies in these sectors remains bleak. We
have also reduced our exposure to the transportation sector based on an
uncertain profit picture.

Emerging Growth Series
For the six months ended June 30, 1997, the Series provided a total return of
10.48%. This compares to a 10.20% return for the Russell 2000 Total Return
Index (the Russell 2000) and to a 20.60% return for the S&P 500 for the same
period. The Russell 2000 is an unmanaged index comprised of 2,000 of the
smallest U.S.-domiciled company common stocks (on the basis of capitalization)
that are traded in the United States on the New York Stock Exchange, the
American Stock Exchange, and NASDAQ. The performance of the Series and the
Russell 2000 relative to the S&P 500 has been hampered by the underperformance
of small, rapidly growing companies, the continuation of a trend that began in
the summer of 1996. Not only have smaller stocks underperformed, but so have
mid-capitalization stocks. Because of this underperformance, we believe the
smaller companies are currently very attractively valued, although we are
unsure what catalyst will re-ignite interest in this sector, or when. However,
we remain confident that earnings growth will eventually be recognized.

One action that we have taken is to increase the Series' average company size
as measured by market capitalization, a move that has helped performance.
Despite this increase in size, we have not altered the Series' growth
characteristics. While a short-term abandoning of our focus might be appealing,
history has shown that a focus on smaller, rapidly growing companies has
rewarded investors (although past performance is no guarantee of future
results).

More important than sector selection this year has been stock selection.
Technology companies have benefited the Series this year, including companies
in the software industry such as Compuware, Altera, BMC Software, and
MicroWarehouse, all of which have been strong performers. Meanwhile, Cadence
Design and Synopsys, both market leaders in the software industry, have been
laggards.

Most health maintenance organizations (HMOs) have performed well this year,
with United Healthcare being an excellent performer.

A major disappointment so far this year has been HFS, Inc., the nation's
largest hotel and real estate franchiser. While HFS has far exceeded analysts'
earnings estimates in each quarter for the past year, enhancing its future
prospects, Wall Street has chosen to ignore the company and its valuation has
suffered, which we believe to be a temporary phenomenon. The management team at
HFS has been responsible for a 14-fold increase in its stock price over the
past five years and, while we are discouraged by the company's recent stock
price performance, cash flow and earnings for this year are substantially in
excess of what we would have expected a year ago, and we see strong gains
ahead.


In the U.S. economy as a whole, there are several sectors in which we see very
strong growth. The software industry is expected to grow its earnings in excess
of 30% in 1997 and in excess of 25% in 1998 -- the fastest growth of any
industry. Similarly, above-average growth is expected for the health care and
consumer industries. These three sectors are among the largest weightings in
the Series, and we expect them to grow their earnings in excess of 20% in 1997,
a healthy pace when compared to the 12% to 13% anticipated earnings growth for
corporate America as a whole.


One sector that did not perform well in 1996, but has rebounded nicely in 1997,
is health care, a resurgence which was reflected in the strong performance of
our large positions in several HMOs. After profit margins compressed in 1996,
premiums have been rising in excess of costs so far this year, a trend we
expect to continue.


MFS(R)/Foreign & Colonial Emerging Markets Equity Series
For the six months ended June 30, 1997, the Series provided a total return of
21.97%. This compares to a 17.87% return for the Lipper Emerging Markets Funds
Index, as determined by Lipper Analytical Services, Inc., an independent firm
that reports mutual fund performance, and to a 17.75% return for the Morgan
Stanley Capital International (MSCI) Emerging Markets Free (EMF) Index, a
broad, unmanaged, market-capitalization-weighted index of equities in emerging
markets. The Lipper indices are unmanaged indices of the largest qualifying
mutual funds within their respective investment objectives, adjusted for the
reinvestment of capital gains distributions and income dividends. Emerging
markets have shown much better performance over the past year after a generally
poor performance in 1994 and 1995. The Series has outperformed the MSCI EMF
Index by having above-index weightings in most of Latin America, including
Brazil, Mexico, Colombia, and Peru, and below-index weightings in South Africa.
The Series has outperformed the Lipper Index primarily due to its


2
<PAGE>

higher weightings in Brazil, Mexico, Colombia, Russia, Egypt, and Morocco,
while having lower weightings in Malaysia, Indonesia, Thailand, and the
Philippines.

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

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

In other emerging markets, Russia, Egypt, Portugal, and Greece deserve special
mention. Russia was among the best-performing markets in the world in 1996 and
continues to move strongly higher in 1997, primarily due to continued
liberalization at the political and company level. The Egyptian economy is the
strongest in the Middle East as a result of efforts by the current
administration to introduce large-scale privatization of state-run companies.
Portugal has demonstrated, over the past 12 months, that its management of its
economy is among the best in Western Europe. This has been validated by the
MSCI, which recently announced that Portugal's stock market will be in its
developed, rather than emerging, market index series beginning in December.
Greece is another country that has decided on an accelerated reform program
following the landslide victory by Prime Minister Simitis in September last
year, which has led to falling inflation and interest rates. Having been
cautious on the South African stock market for most of the past year, we are now
seeing some value there following the sharp fall of the rand and the likely
peaking in inflation and interest rates.


MFS(R)/Foreign & Colonial International Growth Series
For the six months ended June 30, 1997, the Series provided a total return of
3.86%. This compares to an 11.36% return for the MSCI Europe, Australia, Far
East (EAFE) Index, a broad, unmanaged index of non-U.S. equities, and to a
13.98% return for the Lipper International Funds Index. The Series' exposure to
smaller companies was reduced over the past six months, and the money raised
was reinvested in blue-chip stocks. With equity markets being driven by
liquidity and deregulation and restructuring gathering pace, we felt that blue
chips would benefit more than smaller companies. Investors tend to focus on
larger, more liquid stocks when trying to invest large sums of money and, in
addition, the restructuring theme tends to benefit larger companies with more
room to cut costs.

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

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

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

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


Managed Sectors Series
For the six months ended June 30, 1997, the Series provided a total return of
13.61%. This compares to a 20.60% return for the S&P 500. The Series continues
to be invested in many of the same sectors as outlined in our year-end review,
but significant changes within those sectors have occurred over the past six
months. For example, the Series' technology weighting was modestly increased,
despite a major reduction in semiconductor holdings, with the sales of Intel,
National Semiconductor, and VLSI Technologies. Also sold were the Electronic
Arts and Cabletron holdings, and the Sun Microsystem position was reduced.
Proceeds from these sales funded new technology holdings in IBM, Sony, Compaq,
and Synopsys and in networking stocks such as 3Com, Aspect Telecommunications,
Cisco, and Ascend Communications.

The health care sector also saw significant changes, resulting in a modest
weighting reduction. HMO stocks Pacificare Health Systems and Coventry Corp.
were sold due to what we viewed as deteriorating company fundamentals, while
Healthsource was acquired and the stock subsequently tendered. Proceeds from
these moves funded new positions in Aetna and CIGNA, both with growing exposure
to the HMO industry, as well as an increased weighting in United Healthcare,
the leader in the industry. Positions in drug stocks Pharmacia Upjohn and
Rhone-Poulenc Rorer were replaced with Bristol-Myers Squibb. Finally,
HEALTHSOUTH was sold on higher valuation, and new positions focusing on drug
distribution -- Cardinal Health, Amerisource, McKesson, and Smith's Food and
Drug -- were initiated.


                                                                               3
<PAGE>

The "other" category was concentrated to include fewer names, with one of them
being Tyco International which, through its acquisitions of both ADT and
Keystone International, each of which was already held in the portfolio, now
represents over 10% of the Series' assets. Sales were also made of McDonnell
Douglas, Colgate, Sears, PowerGen, and MCI Communications as their valuations
increased, and of Staples, Gymboree, and Advanta Corp. as their fundamentals
changed. Small positions were added in paper stocks such as Stone Container and
Jefferson Smurfit, tobacco stocks Philip Morris and RJR Nabisco, as well as
Waste Management Technologies.

In the leisure category, hotel stocks such as Hilton and ITT Corp. were added,
while positions in HFS and LaQuinta were increased. Among gaming issues, MGM
Grand, Argosy, and Showboat were sold. Energy holdings in the oil services
sector, one of the Series' best-performing areas, continue to be trimmed on
strength, but the original weighting has not changed over the past six months
because we remain confident that the group's earnings momentum will continue
for the foreseeable future.

Looking ahead, expectations of modest economic growth and subdued inflation
should continue to provide a positive backdrop for financial assets,
particularly equities. But this environment, which puts a premium on both the
visibility and growth of earnings, has not gone unnoticed by investors and is,
thus, unforgiving of disappointments. The stock market rally year to date has
broadly discounted much of the good news, resulting in most industry groups
appearing to be fairly valued and further increasing the importance of stock
selection over sector selection. In this environment, we believe the best
course for the Series is to concentrate holdings in companies that are led by
strong management teams and that have visible earnings growth and attractive
relative valuations.

Research Series
For the six months ended June 30, 1997, the Series provided a total return of
13.40%. This compares to a 20.60% return for the S&P 500. The Series'
underperformance can be attributed to four sectors: energy, health care,
retailing, and transportation. The companies held in the Series in each of
these sectors are leaders in their respective industries and, overall,
performed well during the past six months. However, they were unable to
maintain the torrid pace of equivalent sectors in the S&P 500. The Series did
outperform the S&P 500 in the basic materials and utilities and communications
sectors during the past six months.

Sector weightings have shifted based on the MFS industry analysts' changing
best ideas. Most notably, the financial services sector increased by 4.7%. The
slow-growth, low-inflation economic environment has allowed select banks and
insurance companies to flourish during the first half of 1997, and several of
the banking and insurance stocks in the Series have performed well.

Several companies within the chemical and specialty chemical industries,
including du Pont, Air Products and Chemicals, and Praxair, have also enhanced
the Series' return. These companies have achieved strong stock performance
through a focused cost-savings effort and the introduction of new,
higher-margin products and services that have complemented their existing
product lines.

The weighting in the technology sector increased 4.0% during the past six
months. Several stocks in this sector contributed to the Series' performance,
including Microsoft, Compuware, Intel, Compaq, and Lucent Technologies. These
companies have developed solid competitive positions within their industries
that have translated into successful stock performance. We believe that the
earnings outlook for all of the technology companies held in the Series remains
strong.

The Series remains underweighted in energy, automobiles and housing, and
utilities and communications. While individual stocks within these sectors
positively contributed to the Series' return, the MFS analysts have determined
that the earnings outlook for many of the companies within these sectors
remains bleak. The analysts have also reduced exposure to the leisure and
transportation sectors based on what they regard as an uncertain profit
picture.


Research Growth and Income Series
The Series commenced operations on May 13, 1997, and from that date through
June 30, 1997, provided a total return of 2.00%. Due to the short investment
period of the Series, company-specific positions within what the MFS analysts
view as attractive industry sectors had not been completed by June 30. We
expect the Series to be fully invested shortly.

The objective of the Series, which is managed by MFS' committee of industry
analysts, is long-term growth of capital, current income, and growth of income.
Generally, the analysts seek companies with market capitalizations greater than
$2 billion and with what they regard as attractive dividend yields. Each
analyst specializes in two or three industries and performs in-depth,
bottom-up, fundamental analyses of companies within those industries. The
analysts typically seek companies with strong management teams, successful
track records, histories of long-term earnings growth, proprietary products
and/or services, and the potential for market leadership. Each analyst
considers the economic outlook as part of the decision to buy the stock but
does not decide solely based on economic forecasts. Therefore, the stocks
included in the Series will represent companies that the analysts believe offer
the best possibility for capital appreciation regardless of the economic
outlook. The Series' sector and industry weightings are a fallout of the "best
ideas" stock-selection process. However, the analyst committee will revisit
weightings regularly to assure agreement within the changing economic
landscape.

Total Return Series
For the six months ended June 30, 1997, the Series provided a total return of
12.14%, compared to a 20.60% return for the S&P 500 and to a 2.74% return for
the Lehman Brothers Government Corporate Bond Index, an unmanaged, market-
value-weighted index of U.S. Treasury and government-agency securities,
excluding mortgage-backed securities. The pace of economic activity in the
second quarter has slowed from the 5.9% annual rate posted in the first quarter
of 1997. However, the U.S. economy remains firm, which should support corporate
earnings growth. The rate of unemployment remains low, ending June at 5%, and
while inflation has not been a problem in recent years, we are keeping a close
eye out for any signs of an increase.

We believe the continuing strength of the dollar should serve to dampen the
U.S. economy in the near future. Conversely, we feel that the rise in the
dollar's value over the past year should help improve the competitiveness of
many foreign corporations, which could serve to accelerate foreign economies.
Still, investors remain bullish on corporate America, and stock prices have
risen throughout most of the period.

Our allocations remain conservative. At the end of June, 59% of the portfolio
was invested in stocks, preferred stocks, and convertible bonds. We generally
consider a 60% stock weighting

4
<PAGE>

neutral and anything over 65% aggressive. We have been maintaining this
conservative equity posture for some time because, in our view, equities are
not cheap by historical standards. Specifically, the yield on the S&P 500 is
under 2%, which is close to an all-time low.

In selecting stocks for the Series, we prefer to own companies in which we
anticipate stable earnings growth. We also like to pay a price for these
securities (as measured by price-to-earnings ratios, dividend yields, and
price-to-book ratios) that is below the average for the market. We have found
these characteristics in the financial services and industrial goods and
services sectors, both of which did well during the period. Both sectors have
reported solid earnings, while consolidation activity continues to boost values
of financial services stocks.


We continue to be underweighted in the technology and the consumer nondurable
goods sectors. While we feel there are many fine companies in both of these
sectors, we do not think their valuations have been compelling in recent
months.

The performance of aerospace and defense stocks has been disappointing, in part
because, after years of consolidation, the market is beginning to fear that the
industry is in for a period of slow growth. However, we still find this sector
attractive because we believe these companies can continue to produce solid
earnings over the long term. Another disappointment came in the utility sector,
in which the pace of deregulation continues to pick up, bringing uncertainty
and placing lower values on the sector.

Looking ahead, we see a modest growth rate in the U.S. economy over the next 12
months. Over the near term, however, we believe the Federal Reserve Board will
keep a close watch on wage inflation and general economic activity and may
raise interest rates again should economic indicators suggest a stronger-
than-expected economy.

Our bond portfolio represents approximately 32% of the Series, with two-thirds
in corporates and one-third in Treasuries. The duration, or interest-rate
sensitivity, of the bond portfolio has been approximately 5.4 years over the
period.

Given where equity valuations are today, we feel comfortable with our asset
allocation. However, should the stock market correct, we would be looking to
buy additional stocks.

Utilities Series
For the six months ended June 30, 1997, the Series provided a total return of
12.50%. This compares to a 2.31% return for the Standard & Poor's Utility Index
(the Utility Index), an unmanaged, market-value-weighted, total return index of
all utility stocks in the S&P 500. For the same period, the S&P 500 returned
20.60%. Although the Series has outperformed the Utility Index and the other
utility funds tracked by Lipper Analytical Services, Inc. The Utility Index
continues to lag the overall market, primarily due to poor performance by
electric-utility and long-distance telephone stocks.

The Series remains overweighted in natural gas pipelines because these
companies typically offer 10% to 15% growth in earnings per share, the leverage
that comes with an environmentally friendly fuel, risk-management and marketing
skills that the electric utilities need to acquire, and less regulatory risk
than the other utility segments. Columbia Gas and KN Energy are two of the
Series' largest natural gas positions.

The Series is market weighted in the domestic electric-utility sector. We
continue to focus on companies with reasonable valuations that are low-cost
providers in strong service territories and on companies that are positioning
themselves to benefit from deregulation. The restructuring of the industry has
been a positive for the electric utilities, which have underperformed
dramatically over the past several years.

The Series remains underweighted in the domestic telecommunications sector due
to uncertainty over the impact of competition. In addition, many of the
large-capitalization companies need to build up their infrastructure, which
could prove quite costly in the short term (AT&T is the best example).
Worldcom, the nation's fourth-largest long-distance provider, is the Series'
largest telecommunications position because it offers what we regard as an
aggressive management that is correctly positioning the company in this complex
period.

Twenty-six percent of the Series' assets are in the international markets due
to what we see as their generally higher growth rates, better regulatory
environments and, in some cases, very good valuations, albeit with higher
risks. PowerGen, a U.K. electric-generating company, is one of the cheapest
utilities in the world based on growth relative to its earnings and cash-flow
generation. At the same time, Telebras, the leading Brazilian phone company,
enjoys an excellent combination of robust growth and restructuring potential.

Value Series
For the six months ended June 30, 1997, the Series provided a total return of
12.46%. This compares to a 20.60% return for the S&P 500. The three
best-performing sectors of the S&P 500 over the past six months were health
care, which gained 31.5%; financial services, which advanced 24.1%; and
technology, which was up 15.9%. The worst-performing sector was utilities,
which gained 7.9%. The Series was underweighted in health care versus the S&P
500, at 7.9% of the equity portfolio versus 11.7%; market weighted in
financials (14.8% versus 14.9%); and overweighted in technology (13.4% versus
12.6%).

Financial services, our largest sector, is focused on the insurance industry,
in which we expect a continued trend of consolidation. We expect the banking
industry to play a larger role in this trend as government restrictions are
loosened. Technology, our second-largest sector, is primarily focused on
franchise software companies trading at what we see as reasonable prices
relative to their respective growth rates. We try to take advantage of periods
of uncertainty and establish positions at attractive valuations relative to
long-term prospects. Two recent examples include Synopsys and Computer
Associates. Both software companies have significant leadership positions in
attractive markets, but their stock prices have been depressed by short-term
earnings concerns. In each case, we have been able to establish significant
holdings at what we believe are excellent long-term valuations. In retailing,
our third-largest sector, we are focused on grocery stores and drug store
chains. One of our largest holdings, Smith's Food and Drug, recently agreed to
be acquired by Fred Meyer, a grocery chain located in the Pacific Northwest. We
currently plan to hold the Fred Meyer shares we will receive, as we expect
consolidation benefits to be significant. Future consolidation is also expected
as aggressive, well-managed operators such as Safeway look for further growth.
The drug stores are also benefiting from consolidation because the larger
chains are better able to deal with the industry trend toward managed health
care. While growth in this area presents lower gross margins, the large chains
are able to leverage this greater volume through lower operating expenses and,
therefore, derive higher net margins. Two of our holdings, Rite Aid and CVS,
are in the midst of major consolidations that we expect will yield significant
cost savings.

                                                                               5

Our two largest holdings, ADT Ltd. and Tyco International, recently agreed to
merge in a pooling transaction. The surviving entity will be Tyco
International, and we expect significant earnings leverage going forward, with
significant stock price appreciation as cost savings are realized.

Our outlook for the balance of the year is cautious. With stock market
valuations at record levels, we believe the market is vulnerable to any
negative news. We are, therefore, positioned conservatively.

World Growth Series
For the six months ended June 30, 1997, the Series provided a total return of
14.07%. This compares to a 15.62% return for the MSCI World Index, a broad,
unmanaged index of global equities. The Series continues to focus on what we
believe are the fastest-growing companies in the world, in what we consider the
three most attractive markets with the best long-term growth potential: U.S.
small-capitalization and emerging growth stocks; growth stocks in mature
foreign markets, primarily in Europe and Japan; and stocks in emerging markets.
The Series' performance was helped by our investments in the United States over
the past six months and by our overweightings in software and electronics
stocks. The U.S. sector of the portfolio focuses on companies with what we see
as dynamic earnings growth that can achieve significant market share gains in
rapidly growing markets. Thus, our holdings continue to be stocks in
technology, leisure, and business services, including BMC Software, a leading
mainframe software company; HFS, the leading hotel, real estate, and rental car
franchiser; and Learning Tree International, a leading provider of information
technology training to corporations.

Performance was hindered by an underweighting in Germany, where the weak mark
resulted in big gains in the auto and capital goods sectors. However, weaker
local currencies across Europe benefited the Series by helping export-oriented
companies. Performance was also helped by the Series' holdings in dollar-
sensitive exporters in Japan such as Canon, Sony, and TDK, and by
telecommunications companies such as Telecom Italia Mobile, a leading cellular
phone company whose earnings surprised. Our focus on developed foreign markets
continues to be on what we regard as "world class" companies with significant
earnings leverage resulting from recovering domestic and export economies and
new products.

The Series also benefited from continued strong performance in emerging markets
such as Brazil, Russia, the Middle East, and Hong Kong/China, all of which saw
moderate inflation and strong investment flows. Telebras, the leading Brazilian
phone company; Lukoil, a Russian oil company, were among names that contributed
to performance. Our emphasis in this part of the portfolio continues to be on
companies that we see as global low-cost producers and beneficiaries of
government privatization, increasing consumer demand, or growing
infrastructures.

All results are historical and, therefore, are not an indication of future
results. The investment return and principal value of an investment in the
product will vary with changes in market conditions, and shares, when redeemed,
may be worth more or less than their original cost.

Returns shown do not reflect the deduction of the mortality and expense risk
charges and administration fees associated with variable annuity products. Had
these fees and charges been reflected, the results would have been lower.

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, MFS/Foreign &
Colonial Emerging Markets Equity Series*, MFS/Foreign & Colonial International
Growth Series*, MFS/Foreign & Colonial International Growth and Income Series,
Managed Sectors 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, Portfolio 2000. The Managed
Sectors Series, Utilities Series, and World Growth Series are non-diversified
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 Trust benefits under variable 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 valued at last sale prices. Unlisted
equity securities or listed equity securities for which last sale prices are
not available are valued at last quoted bid prices. Debt securities (other than
short-term obligations which mature in 60 days or less), including listed
issues and forward contracts, are valued on the basis of valuations furnished
by dealers or by a pricing service with consideration to factors such as
institutional-size trading in similar groups of securities, yield, quality,
coupon rate, maturity, type of issue, trading characteristics and other market
data, without exclusive reliance upon exchange or over-the-counter prices.
Short-term obligations, which mature in 60 days or less, are valued at
amortized cost, which approximates market value. Non-U.S. dollar denominated
short-term obligations are valued at amortized cost as calculated in the base
currency and translated into U.S. dollars at the closing daily exchange rate.
Futures contracts, options and options on futures contracts listed on
commodities exchanges are valued at closing settlement prices. Over-the-counter
options are valued by brokers through the use of a pricing model which takes
into account closing bond valuations, implied volatility, and short-term
repurchase rates. Securities for which there are no such quotations or
valuations are valued at fair value as determined in good faith by or at the
direction of the Trustees.

Repurchase Agreements - 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 adviser 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.

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
non-hedging 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. It may also use contracts in a manner intended to
protect foreign currency-denominated securities from declines in value due to
unfavorable exchange rate movements. For non-hedging purposes, the 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.

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

Notes to Financial Statements -- continued

regulations. Dividend income is recorded on the ex-dividend date for dividends
received in cash. Dividend and interest payments received in additional
securities are recorded on the ex-dividend or ex-interest date in an amount
equal to the value of the security on such date.

Fees Paid Indirectly - The Series' custodian bank calculates its fee based on
the Series' average daily net assets. The fee is reduced according to a fee
arrangement, which provides for custody fees to be reduced based on a formula
developed to measure the value of cash deposited with the custodian by the
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 necessary.
Foreign taxes have been provided for on interest and dividend income earned on
foreign investments in accordance with the applicable country's tax rates and
to the extent unrecoverable are recorded as a reduction of investment income.
Distributions to shareholders are recorded on the ex-dividend date.

The 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 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.

At December 31, 1996, the following Series had capital loss carryforwards for
federal income tax purposes which may be applied against any net taxable
realized gains of each succeeding year until the earlier of their utilization
or expiration.

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 forward foreign currency
exchange 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 June 30, 1997, is shown on the
following page.

7. Restricted Securities
Each Series of the Trust is restricted from investing more than a certain
amount in securities which are subject to legal or contractual restrictions on
resale. Such restrictions range from between 0% and 15% of the Series' net
assets. At June 30, 1997, the Capital Appreciation Series, Research Series,
Total Return Series and World Growth Series owned the following restricted
securities (consisting of 0.25%, 0.38%, 0.03% and 0.69%, 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 Capital Appreciation Series,
Conservative Growth Series, Emerging Growth Series, MFS/Foreign & Colonial
Emerging Markets Equity Series, MFS/Foreign & Colonial International Growth
Series, Managed Sectors Series, Research Series, Research Growth and Income
Series, Total Return Series, Utilities Series, Value Series, and World Growth
Series, (each a portfolio of MFS/Sun Life Series Trust) as of June 30, 1997,
the related statements of operations for the period then ended, the statements
of changes in net assets for the period then ended and the year ended December
31, 1996, and the financial highlights for the period ended June 30, 1997 and
each of the periods in the five-year period ended December 31, 1996. 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, 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 June
30, 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.

Dear Contract Owners:

An unprecedented combination of generally positive factors has helped the U.S.
economy enjoy a sustained period of relative stability and moderate growth in
which thousands of new jobs have been created every month, inflation remains
under control, and the investment climate -- at least until now -- has been
favorable. For example, 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. Meanwhile,
borrowing by corporations and governments continues to decline, while consumer
confidence is increasing, although consumer debt levels are still uncomfortably
high. While some lenders are beginning to tighten standards to address this
problem, consumer debt and personal bankruptcies continue to rise. Because of
this, plus slight declines in other indicators such as average hourly wages and
the corporate purchasing-managers index, we do not expect the rapid pace of
growth seen in the first quarter of 1997 to continue. While second-quarter
growth has slowed dramatically, we do expect the second half of the year to pick
up once again with real (inflation-adjusted) growth centering around 2-1/2%.

Global Outlook

Increased liquidity has continued to support international equity markets this
year, while disinflationary forces have continued despite somewhat stronger
world economic growth. While the strength of the U.S. dollar versus the Japanese
yen earlier this year resulted in stronger performance for Japanese exporters,
the value-added tax seems to have slowed the overall Japanese economy. In
Europe, meanwhile, uncertainty over European monetary union continues, although
stocks of some European companies have benefited from restructuring and the use
of technology to increase productivity. Perhaps the brightest international
story has been the performance of the emerging markets, all of which have seen
rapidly expanding economies and higher earnings, thanks in part to significant
shifts in their economic policies.

Bond Markets

In the fixed-income markets, we have been encouraged by the Federal Reserve
Board's decision to not raise short-term interest rates at its July meeting. But
we cannot rule out the possibility of future monetary tightening in the second
half of the year if, as we now expect, the economy strengthens in the second
half of 1997. Therefore, our risk/reward outlook for the fixed-income markets is
neutral, and we believe that fixed-income investors should think in terms of
earning the coupon income from their investments rather than seeking possible
gains from price appreciation.

Stock Market

We have been surprised by the strength of the U.S. equity market in the first
half of 1997. Much of this is the result of continuing gains in corporate
earnings. Even as the current recovery enters its seventh year, more and more
U.S. companies have been exceeding analysts' earnings estimates. In the first
quarter of 1997, for example, two-thirds of all companies met or exceeded
analysts' expectations, a trend that could be an important indicator of the
U.S. equity market's future direction. However, while the near-term outlook for
profits is generally favorable, we believe equity valuations have risen to a
point where a cautious investment approach seems warranted.

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 these charges been deducted. We
appreciate your support and welcome any questions or comments you may have.

On behalf of the Board of Trustees,

MFS[Reg]/Foreign & Colonial International Growth
and Income Series

For the six months ended June 30, 1997, the Series, which invests in
international stock and bond markets, provided a total return of 5.96%. This
compares to a 13.98% return for the Lipper International Funds Index, a
stock-fund index, and to a 6.74% return for a blend (70% and 30%) of the
unmanaged Morgan Stanley Capital International (MSCI) Europe, Australia, Far
East (EAFE) Index and the J.P. Morgan Non-Dollar Bond Index (the Morgan Index).
The Lipper mutual fund indices are unmanaged indices of the largest qualifying
mutual funds within their respective investment objectives. The MSCI EAFE Index
is an index of international stocks, while the Morgan Index is an unmanaged
index of bonds issued from 13 countries with remaining maturities of at least
one year. The major feature in international markets this year has been the
strength of the dollar, particularly against the Japanese yen, the German mark,
and the French franc. In January, half the yen exposure and three-quarters of
the mark and franc exposures were hedged into dollars. Stronger growth in the
United States, weakness in the Japanese economy, and uncertainties in Europe
concerning European monetary union (EMU) supported a strong dollar, and we
expect this dollar strength to continue.

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

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

Economic growth, and the equity markets in continental Europe, continued to be
affected by fiscal restraint as member states struggled to meet the Maastricht
criteria. In France, an unexpected general election was called for late
May/early June. This was a gamble by the French president, Jacques Chirac, in
the vain hope that a right-wing government would be returned with a sufficient
majority to push through the economic policies necessary for mon-

                                                                               1

etary union. In Germany, a row erupted between the government and the
Bundesbank over revaluation of gold reserves that might reduce the budget
deficit. This led to accusations of financial dishonesty and increased the
chance that some of the weaker European countries, such as Italy, would be
included in the first round of EMU. The outlook for Europe remains uncertain,
with political upheavals, high unemployment, and EMU concerns on the horizon.

Asian markets showed a mixed performance over the period. Hong Kong performed
well due to positive sentiment over the imminent handover to China. Other
markets, however, did not perform as well due to worries over high valuation
levels.

The fixed-income portion of the Series reflects a neutral weighting among
Europe, Japan, the United States, and the other dollar-bloc countries. U.S.
interest rates appear increasingly attractive from a global perspective. Hence,
we anticipate increasing the weighting in the dollar bloc relative to Europe
once the pickup in core European growth is confirmed and the U.S. market
adjusts to the Federal Reserve Board's tighter policy. In the meantime, we are
maintaining a defensive posture with respect to duration, or interest-rate
sensitivity, in both the dollar bloc and Europe.

The Series remains overweighted in Australian bonds because we believe current
yield spreads reflect undue fears of a rate hike. Within Europe, several
potential developments suggest possible opportunities: the return of the
single-currency theme to the market, which would help potential entrants such
as Ireland and Spain; the likelihood of interest-rate cuts in Italy, Spain, and
possibly Sweden; and a more attractive U.K. market following the election and
moderate interest-rate hikes. Despite extremely low absolute yields, the
Japanese bond market should be well supported by accommodative monetary policy
and domestic institutional flows. Although some of the forces pushing the
dollar up are waning, we believe it should remain firm due to capital inflows
induced by favorable interest rates and moderate growth.

Government Securities Series

For the six months ended June 30, 1997, the Series provided a total return of
2.55%. This compares to a 3.10% 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 what we expect to be a period of stable interest rates
over the remainder of the year. The Series has an overweighting in
mortgage-backed pass-through securities and agency debentures, is underweighted
in U.S. Treasury securities, and has almost no exposure to cash.

The portfolio's duration, or measure of interest-rate sensitivity, is currently
4.1 years, versus a duration of 4.5 years for the Lehman Index. Thirty-five
percent of the portfolio is invested in U.S. Treasury issues, with an emphasis
on 3-year and 10- to 30-year maturity issues. The portfolio also contains a 21%
position in agency securities. These issues are a combination of agency
debentures and Small Business Association loans.

The greatest change in the portfolio has been the reduction in holdings of
mortgage-backed pass-through securities, from over 50% to the current 44%. This
change was made after a long period of superior risk-adjusted returns from the
mortgage sector. Current holdings focus on issues that are not sensitive to a
slowdown in prepayments and that will benefit from the continued strong
momentum in the U.S. housing market.

High Yield Series

For the six months ended June 30, 1997, the Series provided a total return of
6.13%. This compares to a 5.82% return for the Lehman Brothers High Yield
Index, an unmanaged index of publicly issued, noninvestment-grade debt, and to
a 5.66% return for the average fund in the Lipper High Yield Index as measured
by Lipper Analytical Services, Inc., an independent firm that reports mutual
fund performance. During the first half of 1997, the high-yield market remained
one of the best-performing fixed-income asset classes. The market's strength
was due in part to a strong economy and a subsequent low default rate, which
has averaged only 1.8% over the past 12 months. Demand for high-yield bonds has
been exceptionally strong, with net inflows into high-yield mutual funds over
the past year exceeding the levels recorded in any prior year. In addition,
managers of investment-grade accounts have been significant buyers of
high-yield bonds. Although new issuance of high-yield bonds is on track to
challenge the record level set in 1993, supply has not kept pace with demand.
At the end of the period, the yield on the Salomon Brothers High Yield Index
was 9.28%, versus 6.48% for U.S. Treasury notes of comparable maturities (the
principal value and interest on Treasury securities are guaranteed by the U.S.
government if held to maturity). Although the spread between these two yields
has narrowed to a record low 2.80% from 3.22% at the beginning of the year, we
believe the economic environment remains favorable for owning high-yield bonds
due to the general outlook for moderate economic growth and low inflation.

Given the tight level of yield spreads and the length of this economic
expansion, our investment strategy has focused on trying to avoid mistakes. We
have concentrated our holdings in the bonds of better-quality companies because
we do not think investors are adequately compensated for the risks associated
with lower-tier credits. Two industries of note in which we are overweighted
are consumer products and general industrials. In the consumer products sector,
we are invested in such name-brand companies as Westpoint Stevens and Sealy.
Our general industrial holdings are a diversified group of niche manufacturing
companies that are typically leaders in their fields. Such companies include
International Knife, a dominant manufacturer of industrial cutting blades, and
Hayes Wheels, a global supplier of automotive wheels. We reduced our weighting
in the energy sector because we felt that the relatively low yields currently
available in that sector were not appropriate compensation for the commodity
risk associated with these investments.

Money Market Series

For the six months ended June 30, 1997, the Series provided a total return of
2.44%. Interest rates on short-term (90-day) securities increased moderately
during the six months ended June 30, 1997. During this period, the Federal
Reserve Board (the Fed) raised short-term interest rates by 25 basis points
(0.25%), from 5.25% to 5.50%. At the present time, approximately 61% of the
Series is invested in U.S. government or government-guaranteed issues, with the
balance in corporate and bank issues. Investments in the Fund are neither
insured nor guaranteed by the U.S. government and there is no assurance that
the Fund will be able to maintain a stable net asset value. Furthermore, the
average maturity of the Series on June 30, 1997, was 42 days, versus 47 days on
December 31, 1996. 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 help provide maximum security against credit risk.

<PAGE>

Our market outlook over the next few months is neutral, and we expect to
maintain the average maturity in the 45-day range.

World Asset Allocation Series

For the six months ended June 30, 1997, the Series provided a total return of
9.04%. This compares to six-month returns for the following unmanaged indices:
20.60% for the Standard & Poor's 500 Composite Index (the S&P 500), a popular,
unmanaged index of common stock total return performance; 11.36% for the MSCI
EAFE Index; 2.90% for the Lehman Brothers Aggregate Bond Index, an index of
government and corporate bonds including Treasury, agency, and corporate bond
issues and mortgage-backed securities; and a -3.47% return for the J.P. Morgan
Non-Dollar Bond Index. Earlier this year, the Series had moved ahead of its
competition (according to Lipper Analytical Services, Inc., an independent firm
that reports mutual fund performance) as well as many key indices of
international financial performance. However, much of this lead evaporated as
the U.S. stock market again surged in late May and early June. The Series has
been carrying a high cash position relative to a neutral, or 0%, position and
has had a very low U.S. stock weighting. This defensive position resulted from
our belief that the U.S. stock market was fully valued. The Series' objective
is not to try and time the market, but rather to determine relative valuations
of different asset classes around the world. Because of this, we pared back our
U.S. holdings and remain cautious on the U.S. stock market. While this position
has negatively affected the performance of the Series in the short run, we
believe that, over the long term, there are better valuations in other asset
classes. Although the Series has underperformed during the recent surge in the
U.S. stock market, it did perform well during the sell-off in equity holdings
that occurred earlier in the year, and we believe that the risks of another,
similar sell-off are unacceptably high.

Stock-buying euphoria has been fed by a new consensus that the Fed may not
raise rates again and by new evidence that inflation is decidedly at bay. The
current allocations include a 50% weighting in international stocks, in which
our largest holding is PowerGen, the undervalued British electric utility. The
Series has a 10% allocation to U.S. stocks, with a mixture of large-capitalized
value companies and large growth companies. In bonds, we hold 10% in high-yield
(U.S. corporate) and 10% in emerging market bonds such as Brady bonds (U.S.
dollar-denominated restructured bank loans) in Brazil and Argentina, which are
close to being paid off. The rest of the Series (30%) is in cash, as we await a
more opportune moment to invest. As world stock values rise, we find it more
difficult to reinvest because most of the world's stock markets look expensive
relative to bonds and even to cash. We use a combination of quantitative
approaches and real-world common sense from our expert professionals to set our
world allocations, but our basic use of individual security selection and
original company research continues to underpin the strength of the Series.

World Governments Series

For the six months ended June 30, 1997, the Series provided a total return of
- -1.78%. This compares to a -1.23% return for the Salomon Brothers World
Governments Bond Index (the Salomon Index), an unmanaged index of complete
universes of government bonds with remaining maturities of at least five years.

The first six months of 1997 were quite contradictory for the global
fixed-income markets in that the United States, buoyed by a strong consumer
sector, and Japan, helped by strong exports, witnessed very robust economies
during the first quarter. By the second quarter, both economies had slowed
considerably. Meanwhile, the European countries were experiencing pretty much
the opposite; namely, weaker growth at the beginning of the year followed by
strength. However, one common trend throughout the world during this period was
a lack of inflation.

Against this background, most global bond markets rebounded significantly
during the second quarter. As measured in local currency terms by the Salomon
Index, the two best-performing markets year to date were the United Kingdom,
which advanced 6.05%, and Australia, which gained 5.85%. Most of the strength
from the United Kingdom was the result of the Labor Party's winning the
national election and immediately granting the Bank of England independence. In
Australia, the Reserve Bank became less concerned about future economic growth
and more focused on lowering inflation and dealing with higher unemployment.
Accordingly, the bank lowered interest rates. After a strong beginning of the
year, the Japanese bond market underperformed during the second quarter and
ended up the worst performer year to date, gaining just 2.11%. The portfolio
has benefited by being overweighted in the Australian sector, underweighted in
Japan, and moving toward an underweighted position in the United Kingdom after
its central bank's independence was announced.

While the Series' performance has benefited from bond selection during this
period, it was adversely impacted by its lower duration, or sensitivity to
interest rates, in most markets, as we did not anticipate such a significant
slowdown in the United States. Even though the portfolio was overweighted in
the stronger U.S. dollar for most of the period, nondollar currency positions
were largely responsible for the negative nominal returns.

Looking forward, we believe the portfolio will ultimately benefit from a
defensive bond posture. Presently, the U.S. bond market appears close to
reflecting an easing of monetary conditions that we believe will not happen. On
a relative basis, we feel the dollar-bloc countries, in particular Australia
and New Zealand, are the most attractive. In regard to Europe, the expected
interest-rate cuts in Italy and Spain occurred, and we see minimal further
narrowing of interest-rate spreads relative to Germany. Economic growth in
Japan continues at a strong pace, and we expect its central bank to tighten
monetary policy. Consequently, we continue to underweight this sector.

World Total Return Series

For the six months ended June 30, 1997, the Series provided a total return of
7.89%. 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 8.69% 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 from 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 9.01%. In
general, the equity portion of the Series is managed on a "bottom-up," as
opposed to a "top-down," approach. In other words, investment decisions are
based primarily on a thorough analysis of individual companies and,
secondarily, on the macroeconomic analysis of different economies. We believe
this approach serves the Series well in periods of uncertainty, such as may lie
ahead, when the possibility of higher interest rates has increased.

During periods of rising stock prices, stocks often react very little when
companies' earnings are less than expected. However, this has not been the case
in the recent past. Rather, earnings disappointments have been greeted with
savage selling. In this

                                                                               3
<PAGE>

environment, we believe our emphasis on companies that appear more likely to
keep growing during the uncertain period ahead should benefit the Series. The
equity portion of the Series has approximately half of its assets in five
economic sectors: financial services, utilities, energy, health care, and
consumer staples, all of which we expect to experience growth in earnings.

Furthermore, within each sector, there is broad geographic diversification,
with over 60% of equity assets overseas, representing 20 countries. For
example, the health care sector includes companies from the United States, the
United Kingdom, Switzerland, France, Sweden, and Japan. At the same time, we
believe the dividend yields on many of the stocks in the portfolio should help
buffer them from the vicissitudes of the market. Finally, as always, every
effort is made to avoid speculative securities.

The bond portion of the portfolio reflects a neutral weighting among Europe,
Japan, the United States, and the other dollar-bloc countries. U.S. interest
rates appear increasingly attractive from a global perspective. Hence, we
anticipate increasing the weighting in the United States and the other
dollar-bloc countries relative to Europe once the pickup in core European
growth is confirmed and the U.S. market adjusts to the Fed's tighter policy. In
the meantime, we are maintaining a defensive posture with respect to duration,
or interest-rate sensitivity, in both the dollar bloc and Europe.

The Series remains overweighted in Australian bonds because we believe current
yield spreads reflect undue fears of a rate hike. Within Europe, several
potential developments suggest possible opportunities, such as: the return of
the single-currency theme to the market, which would help potential entrants
such as Ireland and Spain; the likelihood of interest-rate cuts in Italy,
Spain, and possibly Sweden; and a more attractive U.K. market following the
election and moderate interest-rate hikes. Despite extremely low absolute
yields, the Japanese bond market should be well supported by accommodative
monetary policy and domestic institutional flows. Although some of the forces
pushing the dollar up are waning, we believe it should remain firm due to
capital inflows induced by favorable interest rates and moderate growth.

Zero Coupon Series, Portfolio 2000

The total return for the Series was 2.29% for the six months ended June 30,
1997, as intermediate-term U.S. Treasury notes moved higher during the period,
with yields on five-year Treasuries rising from 6.25% to 6.38%. 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
until the maturity of the Series.)

All results are historical and, therefore, are not an indication of future
results. The investment return and principal value of an investment in the
product will vary with changes in market conditions, and shares, when redeemed,
may be worth more or less than their original cost.

Returns shown do not reflect the deduction of the mortality and expense risk
charges and administrative fees associated with variable annuity products. Had
these fees and charges been reflected, the results would have been lower.

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,
MFS/Foreign & Colonial International Growth Series, MFS/Foreign & Colonial
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, Portfolio 2000*.
The High Yield Series, World Asset Allocation Series, World Governments Series,
and World Total Return Series are non-diversified 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 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 valued at last sale prices. Unlisted
equity securities or listed equity securities for which last sale prices are
not available are valued at last quoted bid prices. Debt securities (other than
short-term obligations which mature in 60 days or less), including listed
issues and forward contracts, are valued on the basis of valuations furnished
by dealers or by a pricing service with consideration to factors such as
institutional-size trading in similar groups of securities, yield, quality,
coupon rate, maturity, type of issue, trading characteristics, and other market
data, without exclusive reliance upon exchange or over-the-counter prices.
Short-term obligations, which mature in 60 days or less, are valued at
amortized cost, which approximates market value. Non-U.S. dollar denominated
short-term obligations are valued at amortized cost as calculated in the base
currency and translated into U.S. dollars at the closing daily exchange rate.
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
valued at closing settlement prices. Over-the-counter options are valued by
brokers through the use of a pricing model which takes into account closing
bond valuations, implied volatility, and short-term repurchase rates.
Securities for which there are no such quotations or valuations are valued at
fair value as determined in good faith by or at the direction of the Trustees.

Repurchase Agreements - 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 adviser 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 write covered call or put
options for which premiums are received and are recorded as liabilities, and
are subsequently adjusted to the current value of the options written. Premiums
received from writing options which expire are treated as realized gains.
Premiums received from writing options which are exercised or are closed are
offset against the proceeds or amount paid on the transaction to determine the
realized gain or loss. If a put option is exercised, the premium reduces the
cost basis of the security purchased. 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.

Futures Contracts - Certain Series of the Trust may enter into futures
contracts for the delayed delivery of securities, currency, or contracts based
on financial indices at a fixed price on a future date. Upon entering such
contracts, the Series are required to deposit either in cash or securities an


32

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
non-hedging 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. It may also use contracts in a manner intended to
protect foreign currency-denominated securities from declines in value due to
unfavorable exchange rate movements. For non-hedging purposes, the 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.

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

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, whereby interest income on PIK bonds is recorded ratably by the
Series at a constant yield to maturity. 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, 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
reported as operating expenses.

Fees Paid Indirectly - The Series' custodian bank calculates its fee based on
the Series' average daily net assets. The fee is reduced according to a fee
arrangement which provides for custody fees to be reduced based on a formula
developed to measure the value of cash deposited with the custodian by the
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 necessary.
Foreign taxes have been provided for on interest and dividend income earned on
foreign investments in accordance with the applicable country's tax rates and
to the extent unrecoverable are recorded as a reduction of investment income.
Distributions to shareholders are recorded on the ex-dividend date.

The 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 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.

At December 31, 1996, the following Series had capital loss carryforwards for
federal income tax purposes which may be applied against any net taxable
realized gains of each succeeding year until the earlier of their utilization
or expiration.

Services Company (MFS), a subsidiary of Sun Life Assurance Company of Canada
(U.S.), to provide overall investment advisory and administrative services and
general office facilities. Investment advisory fees are computed daily and paid
monthly at an effective annual rate based on a percentage of each Series'
average daily net assets. The agreements also provide that each Series will be
reimbursed for expenses in excess of the expense limitation indicated below,
calculated based on the average daily net assets of each Series for the fiscal
year. Investment advisory fees and expense limitations are as follows:

 *The advisory fee for the World Asset Allocation Series, World Governments
Series, and World Total Return Series is 0.75% of the first $300 million of
average daily net assets of each of the Series and 0.675% of the average daily
net assets of each Series in excess of $300 million. The advisory fee for the
MFS/Foreign & Colonial International Growth and Income Series is reduced to
0.925% of the average daily net assets in excess of $500 million.

The investment advisory agreements with respect to the MFS/Foreign & Colonial
International Growth and Income Series permit MFS to engage one or more
sub-advisers and MFS has engaged Foreign & Colonial Management Limited, an
England and Wales Company, and its subsidiary Foreign & Colonial Emerging
Markets Limited, to assist in the performance of its services.

Under an expense limitation agreement, MFS has assumed expenses for the period
ended June 30, 1997, amounting to $4,496 for the Zero Coupon Series, Portfolio
2000.

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

The Trust pays no compensation directly to its Trustees or officers who are
affiliated with MFS or Sun Life Assurance Company of Canada (U.S.), all of whom
receive renumeration for their services to the Trust from MFS or Sun Life
Assurance Company of Canada. Certain of the officers and Trustees of the Trust
are officers or directors of MFS or Sun Life Assurance Company of Canada.

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 and forward
foreign currency exchange 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 June 30, 1997, is shown on the
following pages.

7. Restricted Securities
Each Series of the Trust is restricted from investing more than a certain
amount in securities which are subject to legal or contractual restrictions on
resale. Such restrictions range from between 0% and 15% of the Series' net
assets. At June 30, 1997, the High Yield Series, World Asset Allocation Series,
and World Total Return Series owned the following restricted securities
(consisting of 0.19%, 0.50%, 0.06%, 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 of MFS/Sun Life Series Trust and Shareholders of The Portfolios
of MFS/Sun Life Series Trust:

We have audited the accompanying statements of assets and liabilities, including
the portfolios of investments, of MFS/Foreign & Colonial International Growth &
Income Series, Government Securities Series, High Yield Series, Money Market
Series, World Asset Allocation Series, World Governments Series, World Total
Return Series, and Zero Coupon Series, Portfolio 2000, (each a portfolio of
MFS/Sun Life Series Trust) as of June 30, 1997, the related statements of
operations for the period then ended, the statements of changes in net assets
for the period then ended and the year ended December 31, 1996, and the
financial highlights for the period ended June 30, 1997 and each of the periods
in the five-year period ended December 31, 1996. 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, 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 June
30, 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.
