Letter from the Chairman

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

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

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

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

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

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

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

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

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

On behalf of the Board of Trustees,


/s/John D. McNeil

Management Review and Outlook

Capital Appreciation Series
For the six months ended June 30, 1998, the Series provided a total return of
19.87%, which compares to a 17.71% return for the Standard & Poor's 500
Composite Index (the S&P 500), a popular, unmanaged index of common stock total
return performance.

The Series' investment philosophy is based on five elements. We seek steady
earnings growth because we believe that earnings drive stock prices. We take a
close look at the quality of a company's management because we feel that
management adds value to a company's prospects. In addition, we focus on
companies that take advantage of positive business trends that can lead to high
growth and expanded margins. We also like to see strong cash flow in our
companies, which can be used for stock buy-backs or acquisitions that can
enhance stock valuations. Finally, we often buy when we believe the price of a
stock is low and its underlying fundamentals are solid enough to make the
correction short term. We sell stocks when any of these elements are missing or
change substantially for the worse.

The portfolio was heavily invested in companies that were strong individual
performers in sectors that did quite well during the first half of the year.
For example, computer software, an area in which


                                                                               1

Management Review and Outlook -- continued

we are more heavily invested in comparison to the S&P 500 (19.1% versus 3.7%),
was up strongly in the first half. Holdings such as Microsoft and BMC Software
all performed quite well. Our investments in broadcast media stocks such as CBS
and Clear Channel also boosted the Series' return thanks to consolidation in the
industry and strong advertising rates. The miscellaneous sector, consisting of
conglomerates, is essentially comprised of Tyco International stock, which had a
very strong year. Tyco has all but perfected the art of buying and integrating
companies effectively. The stock was up about 40% for the first half of the
year.

Looking ahead, we expect continued growth from our technology holdings as
worldwide demand for technology products increases, spurred by the need for
Europe and Asia to make up for their historical lack of investment in the types
of technology that can often boost business productivity. The regions outside
the United States need to keep pace technologically if they wish to compete
effectively in the world economy.

We are equally optimistic about the leisure sector, specifically our broadcast
media investments, because those companies should be able to offer better
advertising packages to potential customers, again thanks to the consolidation
wave.

Some of the stocks that performed well in the first half of the year included
Colgate, which realized a 20% increase boosted by its new Total toothpaste. As
mentioned before, Clear Channel Communications is having an excellent year and
has grown its share price by 37% in the first part of 1998. The company is
benefiting from the consolidation wave but also has good cash flow generation,
strong earnings growth and, we believe, the best management in its industry.
This should be a very good long-term investment. Another impressive stock is
McDonald's, which is undertaking a corporate restructuring designed to improve
efficiency and boost product quality. So far the program has resulted in
increased revenue growth per store and a share price increase of 44% since the
end of 1997.

Even in a bull market, individual stocks can disappoint. Cendant, a hotel, real
estate, and consumer services company franchiser that was created by a merger of
HFS and CUC International, has been a major disappointment. Earlier this year
the company uncovered potential accounting fraud in the former CUC, and we're
closely monitoring the situation while the company reviews its accounting
practices and attempts to uncover the depth of the problem. IKON Office
Solutions, a provider of office products and computer and networking solutions,
also failed to meet its revenue and profitability targets and has performed
poorly as a result.

Regarding the impact of the Asian economic turmoil on the Series, we eliminated
or sharply reduced our holdings in companies that we felt had a large exposure
there. This is most apparent in our semiconductor holdings, in which we are now
underweighted in comparison to the S&P 500. Most prominently, we reduced our
Intel holding. As a result, we feel we have minimized the negative impact of the
Asian crisis on this portfolio.

The Series has little direct investment in European stocks. However, the
strength of the European economies and the easing of barriers to international
trade made possible by the upcoming implementation of a single European currency
could have a positive impact on U.S. stocks in our portfolio that have
significant European exposure. As their markets expand, their earnings growth
may increase as well.

Among the major changes in the portfolio, we eliminated Philip Morris from our
top holdings list. After meeting with corporate management earlier in the year,
we determined that there was little prospect for growth given the current
political situation surrounding tobacco companies. As mentioned previously,
Intel also was reduced in the portfolio. We feel that it's a very good company,
but now is not the time to be investing in its shares due to the potential
impact on the company of the Asian economic slowdown.

For the remainder of 1998, we'll continue to focus on earnings growth because we
believe earnings drive stock prices. At this time, we feel that stocks are at a
high valuation level, and we anticipate limited upside in the values of stocks.
In this type of market, in which earnings missteps are severely punished by Wall
Street, we need to have a high degree of confidence in our portfolio companies'
abilities to generate consistent earnings. We're anticipating moderate gross
domestic product (GDP) growth and moderate inflation. This scenario provides a
good backdrop for the stock market and should result in moderately positive
earnings growth.


Conservative Growth Series

For the six months ended June 30, 1998, the Series provided a total return of
16.89%, which compares to a 17.71% return for the S&P 500.

We feel the strength of this portfolio's long-term performance is the result of
our adherence to a strong investment discipline. We invest in
large-capitalization, high-quality companies, seek growth at a reasonable price,
strive for a dividend yield that is 90% that of the S&P 500, seek to keep
volatility lower than that of the S&P 500, and try to stay fully invested. Just
as important, MFS(R) Original Research(SM), our process of selecting stocks
through in-depth fundamental analysis of companies' earnings outlooks,
managements, business models, competitive strategies, market positions, and
growth prospects, sets us apart and has been a clear factor in our success.

In the financial services sector we're featuring investments in insurance
companies based on their fundamental strengths and as a means of leveraging the
growing trend toward consolidation in this industry. Consolidation will allow
companies to function more efficiently and produce cleaner, more profitable
balance sheets that positively impact share prices. Because consolidation in the
insurance industry is a newer phenomenon than it is in the banking business, we
are focusing less on banking and brokerage stocks. Some key holdings for the
sector include Hartford Financial Services, Chubb, and Allstate.

Air Products, an industrial gas company, is a new stock in the portfolio's top
10 that exemplifies the type of company we seek out. It locates its plants at
customer sites, and customers contract to take a certain amount of product or to
pay the difference for what they don't use. Any excess product that the plant
can make is sold to other customers, which helps keep plants running more
profitably. Also, the company has modified its management compensation plan to
focus on earnings growth. As a result, Air Products is more rigorously examining
its corporate investments, which has helped earnings growth more easily reach
the bottom line. The company has potential earnings growth in the mid teens, and
its stock sells for a reasonable price given its earnings prospects, so we get
growth at a good price.

One of the household names in the portfolio, and a long-term holding, is
Gillette. Its much-touted new razor product is an excellent example of the
strength of the company's business model. Unlike companies that rely on gaining
new customers or increasing consumption among existing customers, Gillette has
built a successful business by constantly improving its products and convincing
customers to pay more for them.

Management Review and Outlook -- continued

Consolidation is a theme that has been prominent in many industries recently.
Among mergers that have had an impact on this portfolio is the one between
American Home Products (AHP) and Monsanto. This is a very strategic merger for
both companies. American Home Products, one of the world's largest
pharmaceutical and health care companies, produces products such as Advil and
Robitussin. Monsanto, in addition to producing well-known products like
NutraSweet and Round-Up, has cutting-edge agricultural products that should
thrive under AHP's management and strong financial discipline. We are optimistic
about the new company's growth prospects.

While the portfolio is allowed to invest up to 35% of assets in international
stocks, we'll probably never reach that level. Currently, we're only about 8%
invested in non-U.S. dollar stocks and feel that 10% to 15% is a reasonable
maximum. We only invest overseas if we find a company with quality and growth
potential equivalent to those of a U.S. company and whose stock is selling at a
discount sufficient to compensate for currency risk. As a result of this
investment strategy, the portfolio doesn't have much exposure to economies in
Asia such as Malaysia, Indonesia, and Singapore. Japan is a consumer economy,
and some of our holdings have a presence there. However, U.S. companies have had
a hard time selling products in Japan because of that country's trade barriers.
This has provided some protection that, combined with the strength of the
European and American economies, has limited the impact of Asian turmoil on
stocks in the portfolio.


Emerging Growth Series

For the six months ended June 30, 1998, the Series provided a total return of
21.17%. This compares to a 4.93% return for the Russell 2000 Total Return Index
(the Russell 2000) and to a 17.71% return for the S&P 500. 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.

Low inflation, low interest rates, and a robust U.S. economy created a positive
backdrop for emerging growth stocks in the first half of 1998. It was, however,
a volatile period. Although seemingly far away, the economic problems in Asia
were probably the most important factors affecting the U.S. market during this
period. Concerns relating to Asia drove liquidity premiums to very high levels
- -- in other words, investors were willing to pay much higher valuations for the
liquidity offered by larger-capitalization stocks. Consequently, the mid-cap and
larger-cap growth stocks in our portfolio tended to outperform the smaller
stocks during this period. Also, concerns about Asia affected companies with
significant exposure to the region, such as technology stocks, many of which
experienced a roller-coaster ride. Fortunately, the portfolio's technology
holdings were primarily in computer software and networking rather than in the
more volatile semiconductor stocks, which have a lot of business in Asia.

The Series continued to benefit from the solid performance of its technology
holdings, whose earnings were surprisingly strong despite issues relating to
Asia. Stocks that contributed to performance included Cisco Systems, Microsoft,
SAP, BMC Software, and Compuware -- all of whose products were in strong demand
by companies seeking increased productivity. Consolidation in the
telecommunications industry helped increase value in holdings such as WorldCom,
MCI, and Global Telesystems. Better-than-expected earnings and industry
consolidation also helped other companies, such as Tyco International and
AirTouch. One stock that did not do as well as we would have liked was Cendant,
the company created by the merger of HFS and CUC International. Earlier this
year the company uncovered potential accounting fraud in the former CUC, and
we're closely monitoring the situation while the company reviews its accounting
practices and attempts to uncover the depth of the problem.

Looking ahead, we see a number of things affecting our market. First, the
potential for interest rates to rise from currently very low levels is something
we're always on the lookout for, given the continued strength of the U.S.
economy and the tight labor market. If rates rise, the valuations of
interest-sensitive stocks such as financials and television and radio
broadcasters could come under pressure. So, to be on the cautious side, we have
trimmed some of our holdings in these areas.

Second, we believe we are at the beginning of a slowdown in profit growth for
both the economy and the S&P 500. We've already seen the early manifestations of
this in the first half of 1998, with earnings disappointments for quite a few
companies. We think this bodes well for emerging growth stocks because many of
them are expected to generate earnings growth far superior to that of the
broader market. As a result, technology continues to be an area of emphasis
since selected software and networking companies are generating some of the
strongest, most consistent earnings growth we have been able to identify.
Another area we believe offers great potential is the business and computer
services market, which includes information technology and outsourcing firms
that help other companies focus on their core businesses.

Telecommunications is another industry displaying opportunities due to increased
competition and global consolidation. In our view, the companies that can grow
the fastest will be well rewarded by the marketplace. Thus, we believe that our
strategy of searching out rapidly growing companies early in their developments
and growth stocks at reasonable prices should benefit investors in 1998.


Managed Sectors Series

For the six months ended June 30, 1998, the Series provided a total return of
11.66%, compared to a 17.71% return for the S&P 500.

The Series has had exposure to two sectors, energy and health care, that had
weak relative performance in the first half of this year. Also this year, oil
supplies increased while demand slackened, particularly in Asia, and stocks
suffered as a result. We continue to have a positive outlook for companies in
the oil services sector such as Cooper Cameron, EVI Weatherford, and Noble
Drilling because of their strong balance sheets and managements. We believe
these stocks will recover.

In health care, while the Series' drug company holdings and retailers such as
CVS and Rite Aid have done well, stocks of nursing homes, health maintenance
organizations (HMOs), and providers of outpatient services have been under
pressure and have thus acted as a drag on the Series' performance. We believe
the difficulties these stocks have had thus far in 1998 are the result of
confusion and concern regarding the regulatory landscape, and any potential
impact on pricing. In our view, the fundamental outlook for these companies is
still promising. The prices of these stocks is attractive given their relative
valuations. We will continue to own them in the absence of any fundamental
changes.

Another important sector in the Series is technology. We've focused most heavily
on software companies and believe their growth will continue to be driven by
worldwide demand due to


                                                                               3
<PAGE>

Management Review and Outlook -- continued

the critical role software plays in improving corporate productivity and
efficiency. Some of our brightest performers here include Microsoft, EMC, Aspect
Telecommunications, Cisco Systems, and BMC Software.

The Series' largest holding is Tyco International, a conglomerate with an
excellent management team that is a leadership position in each of its four
major industry segments. The company has been an aggressive acquirer. Its strong
cash generation further boosts its expansion of operating efficiencies. It has
rewarded the Series with strong performance and, based on our expectations, we
believe the company remains attractive.

Major changes in the portfolio for the first half of the year include reductions
in companies' stocks that had too much exposure to Asian markets. Specifically,
we eliminated semiconductor holdings such as Atmel, Intel, and Micron. These
were replaced in the technology sector by those companies mentioned previously.

We've added to our financial services holdings, particularly in stocks of what
we call "new emerging financial intermediaries," which are secondary lenders,
insurance companies and asset gatherers like Associates First Capital, Morgan
Stanley, and Lincoln National. The portfolio does not have a major focus on big
banks. Individual stock performance in this sector has been boosted by the
continued prospects for consolidation in the industry.

In the first half of this year, we reduced our holdings in hotel and
investments, especially in low- to mid-tier companies, because we anticipate
less growth there due to a slowing U.S. economy and an expected increase in the
supply of hotel rooms. In gaming stocks, we saw no new jurisdictional openings,
and an increase in hotel room supply in Las Vegas resulted in an expectation of
weaker business performance.

For the balance of 1998, we believe the market will continue to feel the impact
of the Asian turmoil. We are optimistic that the better-positioned companies in
the health care industry will rebound, and that energy companies will recover
from a weak first half as supply and demand become more balanced. Technology
will continue to be a mainstay of the Series, and performance there may further
benefit from increased worldwide demand as Europe and Asia step up technology
purchases to keep pace in the global economy.


Research Series

For the six months ended June 30, 1998, the Series provided a total return of
18.62%, compared to a 17.71% return for the S&P 500.

The Series' favorable performance relative to the S&P 500 over the past six
months can be attributed to our relative overweightings in the technology
sector, in which our stocks have rebounded very nicely from a tumultuous fourth
quarter in 1997, and in the retailing and business services sectors, in both of
which our analysts continue to find exceptional performers. The Series is also
overweighted in financial services, which our analysts continue to see as an
attractive sector, and in transportation, in which we have focused on the
industry leaders.

During the first and second quarters of 1998 sector weightings in the portfolio
have not shifted a great deal, as our analysts have maintained their positions
in stocks they feel can be long-term achievers. The only significant changes
have come in the consumer staples and energy sectors. Regarding consumer
staples, we have decreased our position by more than 4% by selling Coca-Cola and
Philip Morris stock. Our food and beverage analyst was concerned that
Coca-Cola's significant Asian exposure could have negative volume and currency
implications for the company, and that the demise of the congressional tobacco
settlement would create further legislative uncertainty and difficulties for
Philip Morris.

In the energy sector, we have increased the portfolio's weighting by over 3%
because our analysts have noticed a compelling trend in oil-sensitive stocks. As
Asian economies fell in the latter part of 1997, a supply and demand
"disconnect" was created because these Asian countries comprise a key component
of global demand. Oil prices plummeted, and oil-sensitive stocks began to
underperform the market. However, our analysts have since picked up on various
signals that this "disconnect" should begin to correct and that oil companies
should benefit from an improvement in oil prices spurred by reduced production.
As a result, we have invested in blue-chip oil companies such as Chevron,
Texaco, and British Petroleum. The risk/reward trade-offs for these companies
have become very attractive recently, and all methods of valuation appear
favorable relative to the market.

Over the past six months our analysts have increased the portfolio's weighting
in health care. Within this sector, the portfolio is overweighted in medical
services and managed care companies such as United Healthcare, HBO & Co., and
Tenet Healthcare, as well as in pharmaceutical companies. In the managed care
industry, our analysts believe that after years of poor pricing the cycle has
finally turned and should translate into substantial margin expansion for these
companies over the next two to three years. Our pharmaceutical analyst continues
to look for companies that are focused on new product development, such as
Bristol-Myers Squibb and American Home Products. Both companies continue to
generate new products and have quite strong growth rates. All of these health
care companies performed very well over the first six months of 1998 and
contributed to the Series' performance.

The portfolio also remains significantly overweighted in the technology sector.
The concentration in this sector has shifted toward companies that participate
in the high-end product market, in which demand has remained strong and in which
we have found good growth opportunities. The Series has trimmed positions in
technology stocks that are more likely to be impacted by the continuing turmoil
in Southeast Asia. Microsoft continues to be the top holding in the portfolio
and has performed exceptionally well over the first two quarters of 1998, during
which the company introduced new products and posted strong earnings. Compuware,
BMC Software, and Cisco Systems are substantial holdings and strong performers.

The Series remains overweighted in retailing, a sector in which companies such
as Rite Aid, Home Depot, and Safeway have enhanced returns, and in the financial
services sector, in which companies continue to benefit from cost-cutting,
consolidation, and low inflation. Conversely, the Series remains underweighted
in utilities and communications relative to the S&P 500 because our analysts
believe that deregulation will decelerate the earnings of the large players in
this industry as competition increases. We are therefore focusing on the smaller
companies that are likely to be acquired in a consolidation environment.

The Series will continue to seek fundamentally strong companies to add in the
year ahead. The portfolio continues to be based upon the research analysts' best
ideas within their industries. Stocks are selected after careful, in-depth
fundamental analysis

Management Review and Outlook -- continued

of companies' earnings outlooks. These companies typically demonstrate dominant
or growing market share, quality products, superior management teams, and strong
financial statements. Portfolio sector and industry weightings are a fallout of
the "best ideas" stock-selection process. However, the analysts revisit
weightings regularly to assure agreement within the changing economic landscape.


Total Return Series

For the six months ended June 30, 1998, the Series provided a total return of
8.71%, compared to returns of 17.71% for the S&P 500 and 4.11% for the Lehman
Brothers Government Corporate Bond Index (the Lehman Index), an unmanaged,
market-value-weighted index of U.S. Treasury and government-agency securities
(excluding mortgage-backed securities) and investment-grade domestic corporate
debt.

Given what we view as high valuations in the stock market, the Series has
maintained a fairly conservative weighting in equities. Currently, approximately
59% of assets are invested in common stocks, convertibles, and preferred
securities, which is below the allocation for the balanced-fund peer group.

As the year progresses, we believe it will become more difficult to make money
in the equity markets. As prices continue to rise, corporate earnings have
slowed and investors have become more selective. At the same time, the
interest-rate environment is favorable, and the perception that rates are going
to stay low, or even move lower, seems to be providing continued support for the
stock market.

In stocks, the Series' largest sector weighting is financial services, an
industry in which valuations are attractive and earnings growth is higher than
that of the average company. Many of the earnings growth rates of these
companies are in the double digits, and their yields are good. Also,
consolidation has made this sector more attractive because these companies are
able to cut costs. Holdings here include National City and PNC in banking and
Lincoln National in insurance.

Another large sector is utilities and communications, in which we see some
attractive valuations. On the electric side, we think growth is modest but
prices relative to anticipated earnings appear good compared to the S&P 500. In
telecommunications, we see not only good valuations but also ongoing
consolidation and growth, both of which we think could enhance capital
appreciation.

We continue to shy away from the technology sector. Given our objective to
provide consistent returns with low volatility, we have not seen much
opportunity within this sector.

Based on our outlook for interest rates remaining low, the duration, or
sensitivity to changes in interest rates, of the Series' bond allocation is
slightly longer than that of the Lehman Index. Most of this allocation is in the
corporate sector because we believe that as long as the economy remains sound
and inflation remains low, corporate bonds should continue to perform well.
About 20% of this allocation is in high-yield corporates. Healthy economic
growth has contributed to the high-yield market's performance as more companies
have posted improved operating results and have had little trouble making their
debt payments. The biggest high-yield sector is media and entertainment and
includes Time Warner, News Corp., and Telecommunications, Inc. This industry
continues to benefit from consolidation and cost-cutting resulting from the 1996
Telecommunications Act.


Utilities Series

For the six months ended June 30, 1998, the Series provided a total return of
11.56%. This compares to a 6.90% return for the Standard & Poor's Utility Index
(the Utility Index), an unmanaged, market-capitalization-weighted, total return
index of all utility stocks in the S&P 500. For the same period, the S&P 500
returned 17.71%.

This is a flexibly managed portfolio that seeks great investment ideas around
the world. The Series seeks to attain its goals of capital appreciation and
steady income by blending stock and bond investments. We invest at least 65% of
our assets in utility companies, while 35% of assets can be invested in foreign
securities. The portfolio is typically allocated 80% to stocks and 20% to bonds
and convertible securities, which has allowed it to achieve solid capital
appreciation and a steady income stream.

The strength of our research has been a key factor in the long-term success of
this portfolio. By gaining a real understanding of companies' fundamental
strengths, the abilities of their management teams, and the regulatory
environment in which utility companies operate, we believe we can pick stocks
that offer the greatest prospects for growth anywhere in the world. It's
important to stress that we don't buy securities on a sector-weighting or
regional-allocation basis. We buy individual companies that meet the portfolio's
criteria. As long as a company's regulatory environment and fundamental outlook
are sound, and we have faith in its management team, we are willing to buy. For
example, Chilectra, a Chilean electric power provider, is a well-run company
that has taken advantage of Chile's very rational industrial regulations to grow
a successful business. Now Chilectra is investing in distribution businesses in
Argentina, Peru, Brazil, and Colombia. We expect that Chilectra's management
strength and business model will help make these other operations successful as
well.

Another attractive stock in our portfolio is CalEnergy, an independent power
provider based in the United States. This is a great company that is making
inroads in both emerging markets like the Philippines, where it serves as a
power generator, and in developed markets such as the United States, the United
Kingdom, and Australia, where it provides both power generation and power
distribution services. We feel the stock represents a good value now and may be
a good partner for a bigger player in the industry.

Because the U.S. gas and electric industries are fairly mature, there is ample
room for cost savings through consolidation in many companies. This could result
in cleaner balance sheets and corresponding boosts in earnings growth and
valuations. Though we feel this would make good economic sense, the realization
of the scenario is hindered by the domestic regulatory environment, which makes
consolidation difficult. The Public Utility Holding Company Act is a roadblock
to consolidation and, until it is repealed, it's unlikely that there will be
much more activity. If the regulations change, we anticipate a flurry of
activity that would be beneficial to individual stocks.

In the telecommunications industry, a company's ability to handle data --
including Internet, fax, and wide-area network traffic -- is the key
differentiator in its ability to compete in the future. In fact, in some parts
of California, electronic data traffic already exceeds traditional telephone
transmissions, and the volume of fax communications there is greater than that
of telephone communications between the United States and Europe. The greatest
opportunities for telecommunications companies lie in bundling

Management Review and Outlook -- continued

Internet and other enhanced services with phone service as a means of broadening
their offerings to customers, enhancing their sales opportunities, and creating
the perception of leadership.

Merger activity in the sector has been heavy and has aided stock performance.
The WorldCom and MCI union is one of the more prominent among these, and
WorldCom continues to be one of the biggest positions in the portfolio. We feel
that the merger will create the best-positioned large-cap telecommunications
company in the world. Both companies grew up with a highly entrepreneurial
attitude that they've used to successfully compete with monopolies in the United
States. They are now exporting that attitude and business model and are finding
success competing against the big telecommunications companies of Europe.


World Growth Series

For the six months ended June 30, 1998, the Series provided a total return of
13.00%. This compares to a 16.86% return for the MSCI World Index, a broad,
unmanaged index of global equities. The Series' performance has been helped by
its overweighting in U.S. technology and European stocks and an underweighting
in Japanese and other Southeast Asian companies. Overall, we've had strong
markets in many parts of the world, driven in part by low or declining interest
rates, very low inflation, and stronger-than-expected economic growth.

At the same time, Japanese stocks with a lot of exposure to the domestic
economy, such as Nippon Broadcasting and Secom, did not perform as well as
expected because the Japanese economy continued to be in the doldrums. In
emerging markets, Egypt suffered as a result of the massacre in Luxor, while
Russia underperformed because of political infighting over the appointment of a
new prime minister. We believe both problems will improve over time. Also, a
major disappointment has been Cendant, a hotel, real estate, and consumer
services company franchiser that was created by the merger of HFS and CUC
International. Earlier in the year the company uncovered potential accounting
fraud at CUC, so we're closely monitoring the situation while the company
reviews its accounting practices and attempts to uncover the depth of the
problem.

In general, the past six months have been a volatile period, but one that has
created opportunities. Concerns relating to Asia drove liquidity premiums to
very high levels -- in other words, investors were willing to pay much higher
valuations for the liquidity offered by the largest-capitalization stocks. So
the Series' large-cap stocks tended to outperform its small and mid-cap stocks.
Also, concerns about Asia affected companies with significant exposure to the
region, such as technology stocks, many, of which experienced a roller-coaster
ride. Fortunately, the Series' technology weightings were primarily in software
rather than the more volatile semiconductor stocks, which have a lot of business
in Asia. Issues surrounding Asia also dampened investors' enthusiasm for other
non-Asian emerging markets, which caused the emerging markets portion of the
Series to contribute less to overall performance. On a positive note, however,
slowing demand from Asia and much lower prices for Asian goods have helped
maintain inflation at unexpectedly low levels in all of the developed markets,
which has helped many of our holdings.

Of the three major markets in which the Series has investments, the United
States remains one of our favorites because of low inflation, low interest
rates, and a robust economy. Among all industries, technology continues to be an
area of emphasis since companies in this sector are generating some of the
strongest earnings growth we've been able to identify. Our holdings are
primarily in software, a sector in which we own leading database, design
automation, and mainframe software companies such as Cadence Design Systems, BMC
Software, Compuware, and Microsoft. These companies have strong new product
cycles, dominant positions, and products that are helping companies around the
world become more productive. Another area that we believe offers great
potential is the business and computer services market. We own, for example,
information technology and outsourcing firms that help other companies focus on
their core businesses.

In the developed foreign markets, our focus is on Europe, where inflation is
low, interest rates continue to decline, and economic growth is accelerating,
all of which is leading to generally positive earnings surprises. Among
companies that we think will benefit from this environment are financial
services companies in Europe that have consolidation and cost-cutting
opportunities similar to those U.S. banks enjoyed in the 1980s. Some of our
favorite companies are Banco Espirito Santo and Banco Pinto & Sotto Mayor in
Portugal and Irish banks such as Anglo Irish and Allied Irish Bank. These
financial services companies are benefiting from the higher valuations of their
counterparts in the United States, where merger and acquisition activity has
been intense. We also like a number of the consumer staples companies in Europe,
where stronger-than-expected consumer demand is leading to positive earnings
surprises. In Japan, we continue to like the blue-chip exporters such as Sony,
TDK, and Kirin Beverages, all of which have been helped by the weak Yen.

Finally, in emerging markets, our favorite regions are Eastern Europe, the
Middle East, and Africa, collectively known as EMEA. For example, in South
Africa valuations are attractive, interest rates are declining, and companies
are beginning to undertake Western-style corporate restructuring. Another
country we think offers opportunity is Egypt, a market with 16% earnings growth
and a 4.5% dividend yield selling only at 11 times next year's earnings. Morocco
is another interesting, surprisingly high-growth market that we view as being
full of many well-managed companies. From an industry perspective, our holdings
tend to be in telecommunications and banking. Growth is still quite healthy for
most telecommunications companies and their valuations are also quite
attractive, while banks are appealing because they are generally growing faster
than the local economy and are selling at below-average valuations.

We are happy to say that, prior to the Asian crisis, we had very little
invested in Southeast Asia. Currently, the only markets that we think are
interesting are South Korea, Malaysia, and, to a lesser extent, Hong
Kong/China. In South Korea, government authorities have undertaken structural
reforms, while Malaysia has managed to avoid significant foreign debt. In
general, though, we still are underweighted in the region because we think the
problems there could last for a while. While currencies have depreciated quite
significantly, as much as 60% to 70% in some cases, many companies are still
overleveraged with foreign debt and many of them are going bankrupt. As a
result, we are being very selective and are looking for companies with strong
balance sheets and good underlying asset quality.

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

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

(1) Investing in small or emerging growth companies involves greater risk than
    is customarily associated with more established companies. These risks may
    increase share price volatility.

(2) The Series may focus its investments in certain sectors, thereby increasing
    its vulnerability to any single economic, political or regulatory
    development.

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

MFS/Sun Life Series Trust
Notes to Financial Statements

(1) Business and Organization

The Trust is organized as a Massachusetts business trust and is registered
under the Investment Company Act of 1940, as amended, as an open-end management
investment company consisting of twenty-six separate Series (the Series) of
shares: Bond Series, Capital Appreciation Series*, Capital Opportunities
Series, Conservative Growth Series*, Emerging Growth Series*, Equity Income
Series, Government Securities Series, High Yield Series, International Growth
Series, International Growth and Income Series, Managed Sectors Series*, Money
Market Series, Massachusetts Investors Growth Stock Series, MFS/Foreign &
Colonial Emerging Markets Series, New Discovery Series, Research Series*,
Research Growth and Income Series, Research International Series, Strategic
Income Series, Total Return Series*, Utilities Series*, World Asset Allocation
Series, World Governments Series, World Growth Series*, World Total Return
Series, and Zero Coupon Series, 2000 Portfolio. 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 reported at market value using last sale
prices. Unlisted equity securities or listed equity securities for which last
sale prices are not available are reported at market value using last quoted
bid prices. Debt securities (other than short-term obligations which mature in
60 days or less), including listed issues 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 foreign currency and translated into U.S. dollars at the
closing daily exchange rate. Options listed on commodities exchanges are
reported at market value using closing settlement prices. Over-the-counter
options on securities are valued by brokers. 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 may enter into repurchase agreements
with institutions that the Series' investment adviser has determined are
creditworthy. Each repurchase agreement is recorded at cost. The Series
requires that the securities collateral in a repurchase transaction be
transferred to the custodian in a manner sufficient to enable the Series to
obtain those securities in the event of a default under the repurchase
agreement. The Series monitors, on a daily basis, the value of the collateral
to ensure that its value, including accrued interest, is greater than amounts
owed to the Series under each such repurchase agreement. Certain Series of the
Trust, along with other affiliated entities of Massachusetts Financial Services
Company (MFS), may utilize a joint trading account for the purpose of entering
into one or more repurchase agreements.

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

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

Forward Foreign Currency Exchange Contracts - Certain Series of the Trust may
enter into forward foreign currency exchange contracts for the purchase or sale
of a specific foreign currency at a fixed price on a future date. Risks may
arise upon entering into these contracts from the potential inability of
counterparties to meet the terms of their contracts and from unanticipated
movements in the value of a foreign currency relative to the U.S. dollar. The
Series will enter into forward contracts for hedging purposes as well as for
nonhedging purposes. For hedging purposes, the Series may enter into contracts
to deliver or receive foreign currency it will receive from or require for its
normal investment activities. Each Series may also use


44
<PAGE>

Notes to Financial Statements -- continued

contracts in a manner intended to protect foreign currency-denominated
securities from declines in value due to unfavorable exchange rate movements.
For nonhedging purposes, the Series may enter into contracts with the intent of
changing the relative exposure of the Series' portfolio of securities to
different currencies to take advantage of anticipated changes. The forward
foreign currency exchange contracts are adjusted by the daily exchange rate of
the underlying currency and any gains or losses are recorded as unrealized
until the contract settlement date. On contract settlement date, the gains or
losses are recorded as realized gains or losses on foreign currency
transactions.

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

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

Tax Matters and Distributions - Each Series of the Trust intends to comply with
the provisions of the Internal Revenue Code (the Code) applicable to regulated
investment companies and to distribute to shareholders all of its taxable
income, including any net realized gain on investments. Accordingly, no
provision for federal income or excise tax is provided. 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. Each Series
files a tax return annually using tax accounting methods required under
provisions of the Code, which may differ from generally accepted accounting
principles, the basis on which these financial statements are prepared.
Accordingly, the amount of net investment income and net realized gain reported
on these financial statements may differ from that reported on each Series' tax
return.

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 tax return of capital.
Differences in the recognition or classification of income between the
financial statements and tax earnings and profits, which result in temporary
over-distributions for financial statement purposes are classified as
distributions in excess of net investment income or net realized gains.


(3) Transactions with Affiliates

Investment Adviser - The Trust has an investment advisory agreement with
Massachusetts Financial Services Company (MFS), an indirect 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. Investment advisory fees

(6) Financial Instruments

Certain Series of the Trust may trade financial instruments with
off-balance-sheet risk in the normal course of its investing activities in
order to manage exposure to market risks such as interest rates and foreign
currency exchange rates. These financial instruments include written options
and forward foreign currency exchange contracts. The notional or contractual
amounts of these instruments represent the investment the Series has in
particular classes of financial instruments and does not necessarily represent
the amounts potentially subject to risk. The measurement of the risks
associated with these instruments is meaningful only when all related and
offsetting transactions are considered. A summary of obligations under these
financial instruments at June 30, 1998 is shown below and on the following
page.

At June 30, 1998, each Series had sufficient cash and/or securities to cover
any commitments under these contracts.


(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, 1998, the Research Series, Total Return Series, and World
Growth Series owned the following restricted securities (constituting 0.29%,
0.11%, and 0.63% 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 furnished by dealers or
by a pricing service, or if not available, are valued at fair value as
determined in good faith by or at the direction of the Trustees.

(8) Line of Credit

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

Independent Auditors' Report

To the Trustees and Contract Owners 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, Managed Sectors Series,
Research Series, Total Return Series, Utilities Series, and World Growth
Series, (each a portfolio of MFS/Sun Life Series Trust) as of June 30, 1998,
the related statements of operations for the six months then ended, the
statements of changes in net assets for the six months then ended and the year
ended December 31, 1997, and the financial highlights for the six months ended
June 30, 1998 and each of the years in the five-years ended December 31, 1997.
These financial statements and financial highlights are the responsibility of
the Trust's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of the securities owned at
June 30, 1998 by correspondence with the custodian and brokers; where replies
were not received from brokers, we performed other auditing procedures. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of the Trust at June
30, 1998, the results of its operations, the changes in its net assets, and its
financial highlights for the respective stated periods in conformity with
generally accepted accounting principles.
